Callsigns are used by Air Traffic Control to denote a specific flight. These can differ from flight numbers in two respects. Some airline radio callsigns are different from the airline’s name, either [..]

Each kind of aircraft is assigned an aircraft type, which is a standardized name for the aircraft. Type codes are assigned by ICAO and consist of two to four letters and numbers. These type codes are [..]

The exact routing a flight will take filed with air traffic control authorities, including specific waypoints the flight will pass over.

Speed, as it relates to aircraft, is more complicated than speed on the ground, as there are different ways to measure speed in flight. The different ways to measure to speed can result in differences [..]

Ground Speed is the speed of the aircraft over the ground; often measured in Knots (nautical miles per hour)

Indicated Airspeed is the air speed taken directly from air speed indicator without any corrections for temperature or pressure.

Calibrated airspeed is the airspeed corrected for position and instrument error and is equal to True Airspeed (TAS) at sea level.

True Airspeed is the airspeed of an aircraft corrected for position and instrument error and taking pressure and temperature into account.

A Mach number is the ratio of True Airspeed to the speed of sound at the altitude of a given flight.

Track is the aircraft’s compass heading, denoted as 1-360.
