Vspeeds Flashcards
Memorize what each Vspeed relates to on the Airspeed Indicator
V-NE
Never Exceed Speed:
KCAS: 160
KIAS: 163
Do not exceed this speed in any operation.
V-NO
Maximum Structural Cruising Speed:
KCAS: 126
KIAS: 129
Do not exceed this speed except in smooth air, and then only with caution
V-A
Maneuvering Speed:
2550 lbs; KCAS: 102; KIAS: 105
2200 lbs; KCAS: 95; KIAS: 98
1900 lbs; KCAS: 88; KIAS: 90
Do not make full or abrupt control movements above this speed.
V-FE
Maximum Flap Extended Speed:
10º Flaps; KCAS: 107; KIAS: 110
10º to 30º Flaps; KCAS: 85; KIAS: 85
Do not exceed this speed with flaps down
V-SO
Stall speed in the landing configuration
V-S1
Stall speed in a specific configuration (eg. ‘clean’ config.)
V1
Rotation speed (55 KIAS)
V2
Takeoff safety speed
Vx
Speed for best angle of climb
Vy
Speed for best rate of climb
White Arc
KIAS Range:
40 - 85
Full Flap Operating Range. Lower limit is maximum weight V-SO in landing configuration. Upper limit is maximum speed permissible with flaps extended.
Green Arc
KIAS Range:
48 - 129
Normal Operating Range. Lower limit is maximum weight V-S1 at most forward C.G. with flaps retracted. Upper limit is maximum structural cruising speed.
Yellow Arc
KIAS Range:
129 - 163
Operations must be conducted with caution and only in smooth air.
Red Line
KIAS Range:
163
Maximum speed for all operations
