These special codes are standardized by the International Civil Aviation Organization (ICAO), so seeing an emergency code in Denver means the same thing as seeing the code in Delhi. The first of these is the code 7500, which signals “unlawful interference,” more commonly referred to as hijacking.
Code 7500 is the code for a hijack of an aircraft. When a pilot enters 7500 in a transponder, they can expect fighter jets to scramble and escort the aircraft to a base.
If there's a radio failure associated with an emergency, the aircraft might alternately squawk 7600 (no radio) and 7700 (emergency). This alerts ATC that the aircraft is declaring an emergency and does not have an operable radio.
7500 is the squawk code set on a transponder when the airplane is subject to unlawful interference or hijack. Hijacking situations are not all that common; however, they do happen. Yes, even on light aircraft!
The squawk codes: 7700 for emergencies, 7600 for communication failure, or 7500 for hijack.
Squawking 7700 in an emergency
The most well know of these is the code 7700. This is used to indicate an emergency of any kind. A pilot will enter this when in an emergency situation - either instructed by ATC after declaring an emergency or without communication if there is no time.
At maximum weight, it only needs 5,800 feet of runway to takeoff.
Squawk is a common term used in air traffic control to describe a specific type of radio signal that comes from the plane's transponder. So this funny word is not just for the birds–pilots of all types of planes get to squawk, too.
The second emergency squawk code is 7600, showing ATC that the aircraft has lost verbal communication. This could mean that it can still hear ATC and yet not respond, in which case the ATC will direct the pilot to speak with them through the Ident button.

Websites such as ADSBExchange.com, FlightRadar24.com and FlightAware.com aggregate flight data in the United States and abroad using a mix of commercial and citizen-owned sensors that capture the movements of commercial, civilian and military aircraft in real time, 24 hours a day.
Emergency codes
The first emergency code that you may have become familiar with is Squawk 7500. This code is used to indicate that the aircraft has been hijacked, and therefore requires urgent emergency support from both security services and air traffic control.
what does a red plane mean on the app? Red icons indicate aircraft that are squawking 7600 or 7700.
7500 is a harrowing thriller that evokes visceral memories of September 11, 2001. Islamic terrorists hijack a German airplane bound for Paris. The entire film takes place inside the cockpit in real time. There is no soundtrack or accompanying score.
Plot. Vista Pacific Airlines flight 7500, a Boeing 747-300, departs from Los Angeles to Tokyo Haneda.
Although this is a fictional story great care was taken to research actual hijackings over the decades, as such it comes off very realistically. Very tense most of the time, it isn't "entertaining" but more eye-opening. (Not to be confused with the 2014 horror movie "Flight 7500".)
Pan-Pan, short for “possible assistance needed,” is used to communicate an urgent, but not emergency, situation over VHF radio, in the case of aviation, to air traffic control. Examples could include a recreational pilot getting lost, or perhaps needing to climb to a higher altitude to sort a problem out.
7777 is the transponder code for fighter jets carrying out an “active air defense mission”, i.e. an emergency interception.
Code 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.
Some squawk codes are reserved, such as 7700 (emergency), 7600 (communication failure), 7500 (hijacking), 1202 (glider), 1200 (VFR), etc. One of these, 7777, is apparently used for "military interception." What does this mean in the United States?
Wake turbulence poses a major risk to other aircraft, so pilots and ATC use the term “heavy” in radio transmissions as a reminder that the aircraft's wake may be dangerous to others passing behind or below the flightpath of these larger-mass aircraft.
For example, "1200" in the USA means that the flight is flying under Visual Flight Rules (VFR) and is not typically in direct contact with ATC. "1200" is a shared code so you may see many aircraft transmitting it at the same time in a given area.
The chart notes that if a Boeing 747-400 had an operational landing weight of 475,000 lbs (215,456 kg) and wanted to land at a runway located at sea level, then the suggested runway length would be a little over 1,500 meters, or roughly 5,000 feet.

The Global 7500 is one of Bombardier's flagship aircrafts. Arnault wasn't the only one who was fond of the jet — several other wealthy individuals, including Kylie Jenner and Australian billionaire Andrew Forrest, have also owned the plane.
