This key can also be labeled “NORM”.

What does the term no joy mean?
1. In military aviation, a term indicating that no visual confirmation of another aircraft (especially an enemy) has yet been made; no information available at this time.
What are the emergency squawk codes?
Just the facts The transponder sends the four-digit squawk code and aircraft altitude to air traffic control. The code should always be 1200, unless another code is assigned by ATC. However, if there is an emergency squawk 7500 for hijack, 7600 for communication failure, or 7700 for emergency.
What does squawk 7700 mean?
Declaring an emergency means the crew determines they have an “urgency” or “distress” situation. … If a crew resets their transponder to the emergency code of 7700 (squawking 7700), all air traffic control facilities in the area are immediately alerted that the aircraft has an emergency situation.
Why do pilots say heavy?
In the United States, the term heavy is used during radio transmissions between air traffic control and any aircraft which has been assigned a maximum takeoff weight (MTOW) rating of 136 tonnes (300,000 lb) or more. All aircraft produce wingtip vortices that create wake turbulence in flight. …
What is nordo aircraft?
In North American aviation, a NORDO (/ˈnɔːrdoʊ/) aircraft is an aircraft flying without a radio. While sometimes used to denote small general aviation aircraft that are not equipped with a radio, the term is more commonly applied to aircraft that have experienced a radio failure while flying.
Why do pilots say squawk?
A squawk code is a discrete transponder code. Air traffic controllers will use the term “squawk” when requesting a pilot to identify their airplane on the air traffic control radar. Pilots will push a button on their transponder to show their location and become correctly associated with their identity.
What is a radio failure alert?
Indicate by aircraft If pilots are flying during the day and find themselves in the situation of a radio failure mid-flight, rocking the aircraft’s wings will signal to ATC that a radio failure has occurred. … This is important in the case that radio communication is lost on both the pilots and and the ATC end.
What does squawk 7500 mean?
If an aircraft transmits or “squawks” 7500, it is understood that the crew is letting everyone know they are being hijacked. The JetBlue pilots were trying to squawk 7600, which is the code for radio failure. They missed by one digit. … These transponder codes are incredibly important in international aviation.

What does squawking mean?
What is a “Squawk”? … Since World War II, squawking has evolved somewhat, and today a squawk refers to a discrete transponder code. These codes are four digit numbers that each respond to secondary surveillance radar interrogation signals sent by ATC to uniquely identify an aircraft on a radar.
What do you do if you lose your contact with air traffic control?
What to Do If You Lose ATC Contact on an IFR FlightSquawk — 7600.Continue flight VFR at a VFR altitude (even in Class A airspace) and land as soon as practicable at the nearest suitable airport.Do not continue to your destination if there is a suitable airport for you to land at unless you’re just minutes from your original destination.
What does squawk 2000 mean?
The purpose of squawk code 2000 is to prevent aircraft entering a Secondary Surveillance Radar (SSR) area from transmitting a code that is the same as a discrete code assigned by ATC to an individual aircraft. If you are flying in the USA under Visual Flight Rules (VFR), you will be assigned (implicitly) code 1200.
What does squawk 7400 mean?
Lost link proceduresCode 7400 may be displayed by unmanned aircraft systems (UAS) when the control link between the aircraft and the pilot is lost. Lost link procedures are programmed into the flight management system and associated with the flight plan being flown.
What does Mode C mean on a transponder?
pressure altitude informationMode A and Mode C When the transponder receives a radar signal it sends back a transponder code (or “squawk code”). … A transponder code can be paired with pressure altitude information, which is called “Mode C”. Mode 3A and C are used to help air traffic controllers to identify the aircraft and to maintain separation.
