D

 
  • Departure: The fact of a person or vehicle, etc. leaving somewhere.

  • Departure facility: A location that controls air traffic leaving from an airport.

  • Descend: Any portion where an aircraft decreases altitude.

  • Downwind leg: A flight path parallel to the landing runway in the direction opposite the landing direction.

  • Deceleration: The decrease in speed over time.

E

 
  • Elevator: A primary flight control surface that controls movement about the lateral axis of an aircraft.

  • Equivalent Airspeed: Calibrated airspeed corrected for the compressibility of air at a non-trivial Mach number.

  • Excessive: Level is something which is more than acceptable.

  • Electrohydraulic Servo Valves: Is control the flow of fluid into the actuators.

  • Emergency descent: A manoeuvre for descending as rapidly as possible to a lower altitude.

  • Extention: Is the range or degree to which a flap can be opened.

F

 
  • Fuselage: An aircraft's main body section.

  • Flaps: A high-lift device used to reduce the stalling speed of an aircraft wing at a given weight.

  • Flight service station: An air traffic facility that provides information and services to aircraft pilots before, during, and after flights.

  • Feederliners: Vary in size, but none carry more than 100 passengers.

  • Flight Information Services: A form of air traffic service which is available to any aircraft within a flight information region. 

  • Flight plan: Documents filed by a pilot or flight dispatcher with the local Air Navigation Service Provider.

  • Fly-by-Wire control system: A system that relies on electrical signals. 

  • Fuel flow: Pounds of fuel consumed per hour.

  • Fuel consumption: The amount of fuel an aircraft uses has a huge bearing on its running costs.

  • Final approach leg: Is the last part of the landing pattern, and is a flight path that follows the direction of the runway, along the centerline.

 

G

  • Ground Airspeed: The speed of an aircraft relative to the surface of the earth.

  • Ground Controller: The person who controls air traffic on the taxiway and directs flights for take-off and landing.

  • Gust: A sudden, strong increase in the speed of wind.

H

 
  • Horizontal Stabilizer: Is a movable surface, typically located at the back of the aircraft, that helps the plane stay level.
