What is ATC transponder?

An aircraft’s transponder (short for “transmitter-responder”) is an electronic device on aircraft that transmits a four digit code (called a “squawk code”) which allows the aircraft to be identified by Air Traffic Control.

What are the Blue aircraft on Flightradar24?

Aircraft displayed as blue icons are currently being tracked via satellite. Satellites are collecting the ADS-B signals from aircraft and transmitting them to the Flightradar24 network. Space-based ADS-B tracking will be used to supplement our terrestrial receiver network.

What is a general emergency on a flight?

Emergency Condition- Request Assistance Immediately

An aircraft is in at least an urgency condition the moment the pilot becomes doubtful about position, fuel endurance, weather, or any other condition that could adversely affect flight safety.

How does Mode C work?

Mode C transponders also transmit altitude information, obtained from the aircraft’s barometric altimeter. … Once an air traffic control computer identifies an aircraft by its address, that aircraft goes into a “roll call.” Subsequent interrogations are transmitted on a schedule.
