1. DEFINITIONS RELATED TO NON-CO₂ AVIATION EFFECTS

1. 'flight information' means at the minimum the call sign as provided in Article 51 of this Regulation, the day and time of departure and arrival of the flight, expressed in Coordinated Universal Time (UTC) and the ICAO codes and/or the International Air Transport Association's (IATA) location identifiers for origin and destination airports allowing for unique identification of the given flight;

2. 'flight phase information' means the split of data (e.g. aircraft 4D position, fuel flow) according to operational flight phases (take-off, climb, cruise, etc.);

3. 'operation flight envelope' means the boundaries of altitude, aircraft speed, and load factor for each flight phase;

4. 'true airspeed' means the speed of the aircraft relative to the air mass through which it is flying, in meters per second (m/s);

5. 'aircraft 4D position' means the four-dimensional position of an aircraft defined by its latitude, in decimal degree; longitude, in decimal degree; and altitude, in pressure altitude, at any given moment of time between beginning and end of the flight;
