Velocity Speeds
|
|
Va
|
Maneuvering- the maximum used in turbulence - usually
decreases as weight decreases. Stall will occur before there is structural
damage.
|
|
Vfe
|
Top of the white arc - maximum for flaps extended
|
|
Vle
|
Landing gear extension - maximum
|
|
Vlo
|
Operation of landing gear - maximum
|
|
Vne
|
NEVER exceed speed! Red line
|
|
Vno
|
Top of the green arc - maximum structural cruising speed
|
|
Vref
|
Reference for final approach to landing usually 1.3 Vso
|
|
Vso
|
Stall with flaps and gear extended - bottom of white arc
|
|
Vs
|
Stall, gear and flaps up - minimum controllable airspeed
|
|
Vx
|
Best angle of climb - most altitude gain per distance
traveled
|
|
Vy
|
Best rate of climb - best time to altitude
|
|
Vz
|
Normal climb - best for cooling and visibility.
