Piper Archer V-Speeds Flashcards
Vso
Stall speed in landing configuration (lower limit of white arc)
Vs
Stall speed with zero flaps
Vr
Rotation speed (start rotation)
Vx
Best angle of climb
Vy
Best rate of climb
Vg
Best glide speed at max weight
Vfe
Maximum flap extension speed (upper limit of the white arc)
Vno
Max structural cruising speed. Do not exceed unless in smooth air (upper limit of green arc).
Vne
Never exceed speed (red line)
Va
Maneuvering speed
White Arc
Flap operating range
Green Arc
Normal operating range
Yellow Arc
Caution range; fly only in smooth air and then with caution.

Maximum demonstrated crosswind speed?
17 knots
Vr (short-field takeoff)
55 KIAS
Vr (soft-field takeoff)
Liftoff at lowest possible airspeed and remain in ground effect to accelerate to 64 KIAS (Vx) to begin climb.
Traffic Pattern Airspeed
90 KIAS
During turbulent or gusty wind conditions, how much “gust factor” should be added to the normal approach speed?
Add 1/2 the gust factor to the normal approach speed.
(For example, if wind is reported 8 gusting to 18, the gust factor is 10. Add 1/2 the gust factor, 5 knots, to the normal approach speed)
Descent speed out of TPA after abeam the numbers?
70-80 KIAS
Base leg speed?
70 KIAS
Speed on short final when landing is assured?
66 KIAS
Downwind leg speed?
90 KIAS
Precision Approach speeds for inbound, descent on glideslope, runway in sight, and landing assured?

70 KIAS
66 KIAS
MDA or Circling speed?
80 KIAS
When does the stall warning horn activate?
Between 5 and 10 knots above stall speed.
