Airspeed Limitations/V-Speeds

These flashcards cover the airspeed limitations and V-speeds crucial for understanding aircraft performance and safety.

Vso

Stall speed at landing configuration, 40 KIAS.

Vs

Stall speed at clean configuration, 48 KIAS.

VR

Rotation speed. 55kts

Vx

Best angle-of-climb speed. 62 KIAS at sea level
67 KIAS at 10,000'

Vy

Best rate-of-climb speed. 74 KIAS at sea level
72 KIAS at 10,000'

VFE

Max flap extended speed, 10° flaps 110 KIAS, 10º-30° 85 KIAS.

VA

Maneuvering speed; do not make full or abrupt control maneuvers above this speed. 105 KIAS at max takeoff weight 98 KIAS @ 2200 lb
90 KIAS @ 1900 lb

VNO

Max structural cruising speed; do not exceed except in smooth air and then only with caution, 129 KIAS.

VNE

Never exceed speed. 163 KIAS

White arc

Indicates stall speeds; begins at 55 KIAS and ends at 85 KIAS.

Green arc

Normal operating range; begins at 55 KIAS and ends at 129 KIAS.

Yellow arc

Caution range; begins above green arc and depicts speeds not recommended for abrupt maneuvers.

Red line

Indicates never exceed speed. 169kias
