Reference Speeds Flashcards
Vr
Rotation speed
The speed at which the pilot applies back pressure to rotate an airplane’s nose upwards during takeoff.
Speed: 71
Vx (at obstacle)
Best angle of climb
The takeoff speed that will give the best climbout in the shortest distance.
Speed: 81
Vy
Best rate of climb
The takeoff speed that will give the best climb in the shortest amount of time.
Speed: 92-96
Go-Around
what speed is it?
Speed: 81
Max cross wind
Speed: 20
Vfe (flaps 50%)
Flaps extended
The highest speed an aircraft can be flown with its flaps extended.
Speed: 150
Vfe (flaps 100%)
Flaps extended
The highest speed an aircraft can be flown with its flaps extended.
Speed: 110
Vref
Landing reference speed
Airspeed used during the final approach and landing of an aircraft.
(it is usually set at 1.3 times the Vs0)
Speed: 78
Vg
Best glide speed
The speed at which an aircraft can glide the farthest at a given altitude.
(Helps pilot’s navigate emergencies like engine failure safely)
Speed: 92-100
Vpd
Parachute release
Maximum speed at which whole aircraft parachute deployment has been demonstrated.
Speed: 133
Vno
Maximum structural cruising speed
The highest speed an aircraft can be safely flown in calm air.
Upper limit of the green arc.
Speed: 164
Vne
Never exceed speed
The maximum speed an aircraft can be flown without risking structural damage or failure.

Speed: 201
Vs0 or Vs
The stalling speed or the minimum steady flight speed in the landing configuration.
Speed: 62
Vs1
The stalling speed or the minimum steady flight speed obtained in a specific configuration.
Speed: 71
Vo
The highest speed at which the aircraft can safely operate in turbulent conditions.
Speed:
133 (3150)
114 (2300)
