FAR 91.215 (b)(3)(ii)-- transponders- significance of "Below the altitude of the ceiling of a Class B or C airspace area or below 10,000' MSL". So in 1957, NATO and the US introduced a common system, now known as the NATO Military Alphabet, which is still in use to date. If not used, regional accents, dialects, and unconventional voice patterns would lead to miscommunications. Unless otherwise specified in a directive or a letter of agreement or coordinated at the time of handoff, do not request an aircraft to change from the code it was squawking in the transferring facility's area until the aircraft is within your area of responsibility. Select TA or TA/RA (if equipped with TCAS) when taking the active runway, If TCAS equipped, deselect TA or TA/RA upon leaving the active runway, but continue transponder and ADS-B transmissions in the altitude reporting mode. Discover more expressions, check out our complete list of military slang. A continuous readout exists only when the altitude filter limits are set to include the field elevation. Some airlines replace Delta (code for d) with an alternative word. Requests must be made to the ATC facility having jurisdiction over that airspace for operation of an aircraft: With an operating transponder, but without Mode C, requested any time, With an inoperative transponder to the airport of ultimate destination, including any intermediate stops, or to proceed to a place where suitable repairs can be made or both, requested any time, That is not equipped with a transponder; requests must be made at least 1 hour before proposed operation, Transponder inspections and tests are governed by Federal Aviation Regulation, A limited radio rating appropriate to the transponder, A limited rating appropriate to the test to be performed, A holder of a continuous airworthiness maintenance program as provided in Part, The manufacturer of the aircraft on which the transponder to be tested is installed, if the transponder was installed by that manufacturer, The TLS is designed to provide approach guidance utilizing existing airborne ILS localizer, glide slope, and transponder equipment, The TLS detects the aircraft's position by interrogating its transponder, Next, it then broadcasts ILS frequency signals to guide the aircraft along the desired approach path, Sensor arrays to detect lateral and vertical position, and, TLS instrument approach procedures are designated Special Instrument Approach Procedures, TLS ground equipment provides approach guidance for only one aircraft at a time, Even though the TLS signal is received using the ILS receiver, no fixed course or glidepath is generated, The concept of operation is very similar to an air traffic controller providing radar vectors, and just as with radar vectors, the guidance is valid only for the intended aircraft, The TLS ground equipment tracks one aircraft, based on its transponder code, and provides correction signals to course and glidepath based on the position of the tracked aircraft, Flying the TLS corrections computed for another aircraft will not provide guidance relative to the approach; therefore, aircrews must not use the TLS signal for navigation unless they have received approach clearance and completed the required coordination with the TLS ground equipment operator, Navigation fixes based on conventional NAVAIDs or GPS are provided in the special instrument approach procedure to allow aircrews to verify the TLS guidance, Civil and military aircraft should operate with the transponder in the altitude reporting mode (consult the aircraft's flight manual to determine the specific transponder position to enable altitude reporting) and ADS-B Out transmissions enabled at all airports, any time the aircraft is positioned on any portion of the airport movement area, This includes all defined taxiways and runways. Instead of displaying 7700 in the data block, ERAM will display EMRG, and STARS/. Notify the operations supervisorincharge of the aircraft call sign. Mission Echo Tango Sierra means Expiration Tour of Service; a phrase used when a service member is on their last tour of duty, and about to retire from the military and begin receiving their veterans benefits. This Proword is the last word of all transmission sequences, and establishes the end of the conversation. This is the same version used by the International Civil Aviation Organization (ICAO) and the military. For instance, Alpha means A, Bravo means B, and so on. All information on the site is taken from a wide variety of publicly available sources. The Military Alphabet is known as a spelling alphabet, used to spell out words and communicate clearly (e.g., row me oh and jew lee ett for R and J). Flashcards - Dont reinvent the wheel. Traditionally each country has allocated transponder codes by their own scheme with little commonality across borders. What happens after this code is transmitted varies, but usually, security forces tend to get involved. Suggest that the aircraft provide a VFR route of flight and maintain radio contact with ATC. Traffic Management Procedures, Automatic Terminal Information Service Procedures, Standard Terminal Automation Replacement System (STARS)-Terminal, Initial Separation of Successive Departing Aircraft, Initial Separation of Departing and Arriving Aircraft, Basic Radar Service to VFR Aircraft - Terminal, Terminal Radar Service Area (TRSA) - Terminal, Special Use, ATC-Assigned Airspace, and Stationary ALTRVs. The military alphabet uses distinct words like Juliet (pronounced Jew lee ett k), Charlie (Char lee), and India (In dee ah), as well as codewords like Tango Yankee, Tango Tang, Tango Mike, and many more, to code and decode messages. Approve or disapprove inflight deviation requests within a reasonable period of time or advise when approval/disapproval can be expected. Categories of flight that can be assigned Code 4000 include certain flight test aircraft, Military aircraft operating in restricted/warning areas or on, After radio and radar contact have been established, you may request other than single-piloted helicopters and single-piloted turbojet aircraft to change from. (if aircraft has been assigned an altitude below the lowest useable flight level), Aircraft not in contact with ATC may squawk, VFR gliders should squawk 1202 in lieu of. To use the alphabet correctly spell out words using these distinct words while enunciating each syllable. Updates are assigned different Military Alphabet letters so pilots know how current its updates are. Here are some code words used by the military that we've decoded for you: 40 Mike Mike - 40 Millimeter Grenade or M203 Grenade Launcher, Echo Tango Sierra - Expiration Term of Service (when somebody is about to finish their tour of duty). Is there a reason beyond protection from potential corruption to restrict a minister's ability to personally relieve and appoint civil servants? Whenever you observe an invalid Mode C readout below FL 180: Issue the correct altimeter setting and confirm the pilot has accurately reported the altitude. It is for if an aircraft is being intercepted by the military, to let ATC know so they can take the appropriate measures. Identification, friend or foe ( IFF) is an identification system designed for command and control. When you observe a Code 7600 display, apply the procedures in paragraph 10-4-4, Communications Failure. You know, now that I think about it, I bet I was told that by retired Air Force guys who mixed up the roles' codes. Controllers should be aware that not all aircraft have a capability to disengage the altitude squawk independently from the beacon code squawk. Wrong spellings might cause a mislabeled package shipment or a misspelled dinner invitation. The lead aircraft in a standard VFR formation flight not in contact with ATC should squawk 1203 in lieu of 1200. Pronounce it "you nee form paa paa". Does learning the military alphabet constitute DOD endorsement? It uses a transponder that listens for an interrogation signal and then sends a response that identifies the broadcaster. Is the squawk code 4000 used to let ATC know that military aircraft are operating at high-speeds and low-levels?!! VERIFY USING TWO NINER NINER TWO AS YOUR ALTIMETER SETTING. FAA Order JO 7110.65, Para 5-2-21, Altitude Filters. The computer will assign only discrete beacon codes unless all the discrete codes allocated to a facility are in use. During WWI, the British Royal Airforce introduced the first complete spelling alphabet, the RAF radio alphabet. Passing parameters from Geometry Nodes of different objects. Operators of aircraft with functional ADS-B Out avionics installed and requesting an exception from the requirement to transmit at all times must obtain authorization from FAA System Operations Security. Likewise, Break and Over will determine whether a particular transmission is a complete message or not. Do airliners have a "switch" or other means of rapidly squawking emergency? The intent of this paragraph is to capture ADS-B anomalies observed by ATC, such as errors in the data (other than Call Sign Mis-Match events, which are detected and reported to AFS automatically) or instances when civil ADS-B transmissions would normally be expected but are not received (e.g., ADS-B transmissions were observed on a previous flight leg). SQUAWK (code). Under no circumstances should a pilot of a civil aircraft operate the (If aircraft is known to be operating at or above the lowest useable flight level), Ask a friend to test you - Some people are not visual learners. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. When unable to validate the readout, do not use the Mode C altitude information for separation. The military alphabet is used to make up Squawk Codes, officially known as Aircraft Transponder Codes, which is used to distinguish flights and aircrafts by air traffic control. transponder on Code 7777. - Determines if the SSR range is to be assigned to traffic who sent an FPL marked as military. In reality, though, you would want your call sign to be less tied to your personal identity. Do this until it becomes learned and second nature. e.g. Over the first half of the 20th century, several different spelling alphabets came in and out of use. Send your comments regarding this website. When you observe a Code 7400 display, do the following: Instead of displaying 7400 in the data block, ERAM will display LLNK, and STARS/MEARTS will display LL.. Military traffic remaining within a controlled aerodrome's circuit should continue to squawk their discrete military code. FAA Order JO 7110.65, Para 5-2-15, Validation of Mode C Readout. 14 CFR Section 91.215(b) provides, in part, that all U.S. registered civil aircraft must be equipped with an operable, coded radar beacon transponder when operating in the altitude stratum listed above. This then communicates with ground equipment to display the aircraft information. Due to equipment inaccessibility, the flight crew may not be able to accept transponder changes identified in this subparagraph. And, you've learned the history of the military alphabet from its early Able Baker Alphabet roots. pforkes December 8, 2009, 1:17pm 1. Radio operators in the armed services use this alphabet when sending codes or relaying important messages. Adhere to the following sequence of action when an inflight VFR deviation request is received from an aircraft with an inoperative transponder or Mode C, or is not Mode C equipped: Suggest that the aircraft conduct its flight in airspace unaffected by the CFRs. A spelling alphabet ensures clear communication even when there's heavy background noise or severe radio interference. Inform an aircraft when its transponder appears to be inoperative or malfunctioning. Whenever you observe an invalid Mode C readout at or above FL 180, unless the aircraft is descending below Class A airspace: Verify that the pilot is using 29.92 inches of mercury as the altimeter setting and has accurately reported the altitude. When your area of responsibility contains or is immediately adjacent to a restricted area, warning area. What is Transponder Code 2000 actually used for? Are transponder codes 7701 - 7777 ever used? A CSMM alert will occur when the transmitted. A pilot may be requested to squawk a given code by an air traffic controller, via the radio, using a phrase such as "Cessna 123AB, squawk 0363". Save my name, email, and website in this browser for the next time I comment. If you want to learn prowords, military slang, or other terms, make cards for those phrases and their definitions as well. The IRSA remains in use today, and has only grown more popular with time. Safety alerts/traffic advisories may be issued to an aircraft prior to coordination if an imminent situation may be averted by such action. SQUAWK (code). A squawk code is a four-digit number assigned to each aircraft that aids in identification. AM radio technology-enabled pilots to coordinate with ground control, but poor signal and radio interference caused frequent errors. Typically, radio messages will feature at least one of these Prowords. Unless otherwise specified in this section, a facility directive, or a letter of agreement, issue beacon codes assigned by the computer. For example, Roger/Negative/Over/Break are just as foundational to aircraft communication as military radio communication. Radio communication is the most important way soldiers communicate during operations and conflict, and therefore has the most codified structure. or FAA Order JO 7110.66, National Beacon Code Allocation Plan. Coordination should be effected as soon as possible thereafter. A squawk code is a four-digit code ATC gives pilots to manually enter into their transponders. However, 14 CFR 91.215 does not include this airspace for ATC transponder requirements. Air traffic managers may authorize temporary suspension of this requirement when target clutter is excessive. Pilots enter the squawk code into the aircraft transponder. Transmissions are often interrupted or broken up, so it becomes unclear whether you are repeating a transmission or requesting a transmission be repeated. Miscommunication can cause loss of lives and other tragic circumstances. Aviation Stack Exchange is a question and answer site for aircraft pilots, mechanics, and enthusiasts. Select STBY or OFF for transponder and ADS-B upon arriving at the aircraft's parking spot or gate, Transponders are all effective at integrating traffic into systems like the Airport Surface Detection Equipment Model X (ASDE-X) and Advanced Surface Movement Guidance and Control System (A-SMGCS), Unless otherwise requested by ATC, aircraft equipped with an ATC transponder maintained in accordance with 14 CFR Section 91.413 MUST operate with this equipment on the appropriate Mode 3/A code, or other code as assigned by ATC, and with altitude reporting enabled whenever in controlled airspace. Enabling a user to revert a hacked change in their email. General Aviation. No person may operate an automatic pressure altitude reporting equipment if: When deactivation of that equipment is directed by ATC; Unless, as installed, that equipment was tested and calibrated to transmit altitude data corresponding within 125 feet (on a 95 percent probability basis) of the indicated or calibrated datum of the altimeter normally used to maintain flight altitude, with that altimeter referenced to 29.92 inches of mercury for altitudes from sea level to the maximum operating altitude of the aircraft; or, Unless the altimeters and digitizers in that equipment meet the standards of TSO-C10b and TSO-C88, respectively. How SQUAWK Codes Work: The Basics What does this mean in the United States? The following must be accomplished on a Mode C equipped VFR aircraft which is in emergency but no longer requires the assignment of, An aircraft experiencing a loss of two-way radio communications capability can be expected to squawk, Instead of displaying 7600 in the data block, ERAM will display RDOF, and STARS/, Determine the lost link procedure, as outlined in the Special Airworthiness Certificate or Certificate of Waiver or Authorization (. Important note: avoid using the word repeat. Do this at least once a day, and try to get as many of the letters right as you can. Each lost link procedure may differ and is dependent upon airframe and operation. . The Able Baker Alphabet, like Morse Code, was designed to minimize miscommunication and is used in non-military settings where codes and clarity are key. For a soldier, miscommunication can spell disaster. (Name of facility or control function) BEACON INTERROGATOR INOPERATIVE/MALFUNCTIONING. or Copyright 2023 CFI Notebook, All rights reserved. Special use Mode 3/A codes are reserved for certain pressure suit flights and aircraft operations above FL 600 in accordance with FAA Order JO 7610.4, Special Operations. The beacon code is often preset on the ground for such flights and is used throughout the flight profile, including operations below FL 600. i.fb-icon-element.fontawesome-icon.fb-icon-element-1{ color: #ffffff;}i.fb-icon-element.fontawesome-icon.fb-icon-element-1:hover { color: #ffffff;} Radar Server is Fully Operationali.fb-icon-element.fontawesome-icon.fb-icon-element-2{ color: #ffffff;}i.fb-icon-element.fontawesome-icon.fb-icon-element-2:hover { color: #ffffff;}. Ask a friend or family member to test your knowledge and help you keep track of the letters you have trouble remembering. The ATC orders don't add anything useful and a lot of security procedures are classified, or at least not publicly available on faa.gov. FAA Order JO 7110.65, Para 5-3-3, Beacon/ADS-B Identification Methods. STOP SQUAWK. FAA Order JO 7110.67, Para 19, ATC Security Procedures for ADS-B Out OFF Operations. Cartoon series about a world-saving agent, who is an Indiana Jones and James Bond mixture, Invocation of Polski Package Sometimes Produces Strange Hyphenation. YOUR ADS-B TRANSMITTER APPEARS TO BE INOPERATIVE / MALFUNCTIONING. Besides error-free spelling, men and women in the service use the Alpha Bravo Charlie Delta alphabet as shorthand and slang. At or above 10,000' MSL over the 48 contiguous states or the District of Columbia, excluding that airspace below 2,500' AGL; Within 30 miles of a Class B airspace primary airport, below 10,000' MSL. The best answers are voted up and rise to the top, Not the answer you're looking for? These aircraft may conduct operations without a transponder or ADS-B Out when operating: Outside any Class B or Class C airspace area; and, Below the altitude of the ceiling of a Class B or Class C airspace area designated for an airport, or 10,000 feet MSL, whichever is lower, 14 CFR Section 99.13 requires all aircraft flying into, within, or across the contiguous U.S. ADIZ be equipped with a Mode C or Mode S transponder. FAA Flight Standards Service, Safety Standards Division (AFS) is responsible for working with aircraft operators to correct ADS-B malfunctions. This website uses cookies and third party services. You will need to know what these mean, and how they stand-in for and abbreviate longer messages. Military Alphabet - For Precise Military Communication. You have learned the words that match each of the 26 letters in the military phonetic alphabet to communicate more clearly. You may instruct an aircraft operating on an assigned code to change the transponder/ADS-B to standby position: FAA Order JO 7210.3, Para 3-6-3, Monitoring of Mode 3/A Radar Beacon Codes. Record yourself and play it back - Make an audio recording on your phone or computer, and listen to yourself saying the military alphabet back to yourself. The aircraft must also be equipped with automatic pressure altitude reporting equipment having a Mode C capability that automatically replies to Mode C interrogations by transmitting pressure altitude information in 100-foot increments. All other requests for deviation must be made at least 1 hour before the proposed operation, following the procedures contained in Advisory Circular (AC) 90-114, Automatic Dependent Surveillance-Broadcast Operations, Unless otherwise instructed by an ATC facility, adjust transponder/ADS-B to reply on Mode 3/A Code 1200 regardless of altitude, Firefighting aircraft not in contact with ATC may squawk 1255 in lieu of 1200 while en route to, from, or within the designated fire fighting area(s), VFR aircraft flying authorized SAR missions for the USAF or USCG may be advised to squawk 1277 in lieu of 1200 while en route to, from, or within the designated search area, Gliders should squawk 1202 in lieu of 1200, regardless of if in contact with ATC or not, When required to operate their transponder/ADS-B, pilots must always operate that equipment with altitude reporting enabled, unless otherwise instructed by ATC or unless the installed equipment has not been tested and calibrated as required by 14 CFR Section 91.217, If deactivation is required, turn off altitude reporting, When participating in a VFR formation flight that is not receiving ATC services, only the lead aircraft should operate their transponder and ADS-B Out, All other aircraft should disable transponder and ADS-B transmissions once established within the formation, If the formation flight is receiving ATC services, pilots can expect ATC to direct all non-lead aircraft to STOP SQUAWK, and should not do so until instructed, Since gliders may fly an unpredictable flight path, varying altitude and speed, VFR pilots not in contact with ATC should squawk 1202, Air traffic controllers, both civil and military, will use the following phraseology when referring to operation of cooperative ATC surveillance equipment, Except as noted, the following ATC instructions do not apply to military transponders operating in other than Mode 3/A/C/S, You may sometimes hear pilots respond to a call to ident by saying "with the flash", Mode 3 Code 7700 and emergency feature for military transponder), Transponders should be operated in the altitude report mode any time an aircraft is on the movement area of an airport in accordance with, The Federal Aviation Administration (FAA) uses airport surface surveillance capabilities at some of the busiest airports in the U.S. to determine aircraft and vehicle location when they are operating on an airport movement area, Runway safety systems, such as Airport Surface Detection EquipmentModel X (ASDE-X) and Advanced Surface Movement Guidance and Control System (A-SMGCS), use data from surface movement radar and aircraft transponders to obtain accurate aircraft and vehicle locations, thereby increasing airport surface safety and efficiency, Distinguishes aircraft from one another on secondary surveillance radar, Air Traffic Control Radar Beacon System (ATCRBS) tracks transponders, If entering a U.S. Offshore Airspace Area from outside the U.S., the pilot should advise on first radio contact with a U.S. Radar ATC facility that such equipment is available by adding "transponder" to the aircraft identification, If deactivation is required, ATC will report "Stop altitude squawk, altitude differs (number of feet) feet", Transponders are preset to 29.92; having the wrong altimeter setting will not affect altitude readout, Mode 3/A, identification only (known as mode 3 for military, A for civilian), Currently ATC automation relies on the Mode 3/A code to identify aircraft under radar surveillance and correlate the target to a flight plan. Many refer to the military alphabet as a phonetic alphabet. FAA Order JO 7110.65, Para 5-1-2, ATC Surveillance Source Use. These words are used to ensure oral communication is clearly understood. (If the altitude read back is not correct), Yep, I have been wrong for about 10 years now.

Current FAA automation systems track multiple targets on the same beacon code with much greater reliability than their predecessors, and a code change may not be necessary for such flights. Maverick, Iceman, and Viper are all call signs you are likely familiar with because of those iconic characters. AFFIRMATIVE (altitude). To solve this problem, flight associations started using code words to represent easily confused letters. I would have sworn the craft being intercepted was the squawker of 7777. This is sometimes known as the Aviation Alphabet. Aircraft equipped with ADS-B are also still required to have an operable transponder. Vectair is an online resource for quickly finding ICAO, IATA and Mode S codes as well as callsigns for airlines, military and other operators. FAA Order JO 7110.65, Para 5-3-3, Beacon/ADS-B Identification Methods. The Association of Anaesthetists advocate for changing the NATO phonetic alphabet for medical telecommunication when necessary. To recap: Each word like "Uniform" (you nee form) or "Yankee" (yang key) represents a letter of the English alphabet. If the altitude readout continues to be invalid: Instruct the pilot to turn off the altitude reporting part of his/her transponder and include the reason; and. SQUAWK codes are four digits and they are used to easily identify a specific aircraft when detected on a radar, or to determine what an aircraft needs in the case of an emergency or situation in which a flight plan needs to be changed. All other aircraft in the formation should squawk standby. (If aircraft has been assigned a flight level at or above the lowest useable flight level), Aircraft Communication Military Alphabet Uses and Notes. The idea is for U.S. soldiers to be able to identify each other and communicate without revealing too much, even if messages are intercepted. After running through this guide, youll be able to clearly get your message across to anyone. Airport Traffic Control - Terminal, Chapter 11. (For a military aircraft when you do not know if the military service requires that it continue operating on another mode), Duplicate ICAO Address Alerts appear as DUP and are associated with the DB on MEARTS systems. The system identifies an aircraft through a four-digit octal number (each digit from 0 to 7), which provides for up to 4,096 possible codes. ATIS also features a lot of Military letters and numbers to communicate logistical data.

STOP SQUAWK (mode in use). Think about the military alphabet as you read and write normally - Thinking about the military alphabet will help you get more comfortable with using it. Phraseology Meaning Remarks Pilot: Station, callsign, passing current altitude, climbing (descending) to altitude, other ATC clearances assigned Controller: Callsign, station, radar contact, (squawk new squawk code), (new clearances) The pilot has just been transferred to another controller and contacts him/her announcing the current altitude, the altitude (s)he was cleared to and any other . Therefore, be sure to use different ordering, pairings, and several methods and techniques to master the alphabet. Mode A Explained. This is a great way to increase your familiarity and use of the alphabet. When communicating code, Oscar Tango Mike is military code for "On the move". These codes can also be used to alert controllers of an . As we explain further in the History section of this page, this alphabet was actually developed by the International Civilian Aviation Organization (ICAO) as a set of terms that would be mutually comprehensible across the international community. You've learned code words used in both the United States and the Royal Air Force. or How far can a plane squawking 7700 be heard and how quickly will the news spread?

FAA Order JO 7110.65, Para 5-3-3, Beacon/ADS-B Identification Methods. ERAM facilities are not required to validate Mode C altitude readouts after accepting interfacility handoffs from other ERAM facilities, except: After initial track start or track start from coast is required, or. Mode A is the most basic . Break is inserted to keep transmissions short. You have correlated the altitude information in your data block with the validated information in a data block generated in another facility (by verbally coordinating with the other controller) and your readout is exactly the same as the readout in the other data block. Lost link procedures are programmed into the flight management system and associated with the flight plan being flown. Is there a grammatical term to describe this usage of "may be"? This would mean that the interceptor aircraft would change it's squawk to 7777 for the military/civilian air traffic controller to see it properly (if not filtered out on civil radars). These items are contained in the flight's Certificate of Authorization or Waiver (, Some UA airframes (Global Hawk) will not be programmed upon the. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Code 7400 may be transmitted by unmanned aircraft systems (UAS) when the control link between the aircraft and the pilot is lost. (In climbing/descending situations), VERIFY ASSIGNED ALTITUDE/FLIGHT LEVEL (altitude/flight level). For example, to say dog, one would say Delta-Oscar-Golf. None of the 26 codewords sound alike, so there is no doubt in what is being communicated. 14 CFR Section 91.225(f) requires, in part, that each person operating an aircraft equipped with ADS-B Out must operate this equipment in the transmit mode at all times unless otherwise authorized by the FAA when that aircraft is performing a sensitive government mission for national defense, homeland security, intelligence or law enforcement purposes, and transmitting would compromise the operations security of the mission or pose a safety risk to the aircraft, crew, or people and property in the air or on the ground.. Additionally, monitor. Inform an aircraft when you want it to turn on/off the automatic altitude reporting feature of its transponder. Code Use Conditions / Remarks Country / Region; 3646: Cardiff Approach: United Kingdom: 3701: Guernsey Approach: United Kingdom: 3701: Military aircraft under service from RN AEW aircraft in South West Approaches: United Kingdom: 3701: RAF Brize Norton: United Kingdom: 3701: RAF Lossiemouth: United Kingdom: Ian Petchenik Updated: October 20, 2022 We track hundreds of thousands of flights every day and invariably a few will declare an emergency and possibly "squawk 7700" during the day. The complete military alphabet is revealed in chart below. Banks use the military phonetic alphabet to communicate security codes and to verify customer information. Squawk codes can be used to identify aircraft type, as a way for ATC to keep track of individual flights, and as a means of communication in emergency situations. Thanks, Peter. What is IFF (Identification, Friend or Foe)? FAA Order JO 7210.3, Para 2-1-33, Reporting Inoperative or Malfunctioning ADS-B Transmitters. STOP ALTITUDE SQUAWK. This is the same insiders strategy used by the International Civil Aviation Organization, Royal Air force, International Telecommunication Union, North Atlantic Treaty Organization, Australian Armed Forces, American National Standards Institute, military veterans, army infantry, and government agencies around the world. A link to the US intercept procedures is here. (Location) ALTIMETER (appropriate altimeter), VERIFY ALTITUDE. This code shall be assigned when either a VFR or IFR clearance is issued. Pilots rely on the Automatic Terminal Information Service (ATIS), which provides a continuous broadcast of weather information, runway logistics, and other vital information. You may approve an inflight deviation request which includes airspace outside your jurisdiction without the prior approval of the adjacent ATC sector/facility providing a transponder/Mode C status report is forwarded prior to control transfer. The code change, based on pilot concurrence, the nature of the emergency, and current flight conditions, will signify to other ATC facilities that the aircraft in distress is identified and under ATC control. Duplicate ICAO Address Alerts appear as Duplicate 24-bit Address at the AT Specialist Workstation on ERAM systems. The Joint Army / Navy Phonetic Alphabet, also known as the Able Baker Charlie alphabet, can be heard in movies and TV shows dating from the 1950s. Introduction Identification, friend or foe (IFF) is a radar-based identification system designed for command and control. Aviators often use many of the same prowords and slang terms as the military, and conduct radio communication using similar norms. We also provide you explanations for each code as well as a useful pronunciation guide and easy method for memorizing the entire military alphabet. Read the alphabet before you go to sleep - if you struggle with memorization, try spending some time reading the alphabet before you go to sleep. The controller handbook says the Mode C information must be within 300 feet of the pilot's report to be considered valid and legally useable, Controller must validate Mode C at least once in each facility's airspace, The controller may request the pilot to say "say altitude" to prompt the report and satisfy the requirement, The transponder ident feature allows for an aircraft to be identified by air traffic control, The transponder/ADS-B Out equipment must be operated only as specified by ATC, Activate the "IDENT" feature only upon request of the ATC controller, When making routine code changes, pilots should avoid inadvertent selection of Codes 7500, 7600 or 7700 thereby causing momentary false alarms at automated ground facilities, For example, when switching from Code 2700 to Code 7200, switch first to 2200 then to 7200, NOT to 7700 and then 7200. Transponder Code Designation: For ATC to utilize one of the 4096 discrete codes, a four-digit code designation will be used; for example, code 2102 will be expressed as "TWO ONE ZERO TWO" Circumstances may occasionally require ATC to assign a non-discrete code; i.e., a code ending in "00" All other aircraft should disable transponder and ADS-B transmissions once established within the formation, A pilot on an IFR flight who elects to cancel the IFR flight plan prior to reaching their destination, should adjust the transponder/ADS-B according to VFR operations, If entering a U.S. OFFSHORE AIRSPACE AREA from outside the U.S., the pilot should advise on first radio contact with a U.S. radar ATC facility that such equipment is available by adding "transponder" or "ADS-B" (if equipped) to the aircraft identification, It should be noted by all users of ATC transponders that the coverage they can expect is limited to "line of sight" with ground radar and ADS-B radio sites, Low altitude or aircraft antenna shielding by the aircraft itself may result in reduced range or loss of aircraft contact, Though ADS-B often provides superior reception at low altitudes, poor coverage from any surveillance system can be improved by climbing to a higher altitude, Transponders have a variety of uses that extend beyond their original design of identification to ATC, These include collision avoidance systems and the aforementioned transponder landing system, If transponders are inoperable and the aircraft must be flown to another location for maintenance, but must be flown through transponder required airspace, consider reaching out to ATC to verify if a waiver is possible, Specific details concerning requirements to carry and operate Mode C transponders and ADS-B Out, as well as exceptions and ATC authorized deviations from those requirements, are found in 14 CFR Sections 91.215, 91.225, and 99.13, Some transponder operating modes can transmit additional data (i.e., mode-s can broadcast callsigns).
