Answer 2

Basic terminologies used in civil aviation:

1. Aerodrome: The location where the operation of the aircraft takes place.
2. ATC: Air Traffic Control, the system who control the bus to the land and to air.
3. Crosswind: The wind perpendicular to the motion of the aircraft.
4. DME: Distance-Measuring Equipment, an equipment that measures continuous slant range distance from station.
5. Final: The final approach of the aircraft that is landing.
6. Freedom of the air: The right of the commercial aviation that governs the carriage of payload.
7. Ground speed: The speed of the aircraft relative to the ground.
8. Mayday: The distress call of the pilot during a danger.
9. Non-Revenue: The passengers flying in free of cost which is majorly defined as employees pass.
10. Pax: Defines the passengers.
