Airspeed Limitations/V-Speeds

These flashcards cover the airspeed limitations and V-Speeds for aircraft, including definitions and specific speed values.

V so

Stall speed at landing configuration; 40 KIAS.

V₁

Stall speed at clean configuration; 48 KIAS.

VR

Rotation speed; 55 KIAS.

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; used to identify flap range., 10º flaps 110 KIAS

10º-30º 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, End of green arc.

Beginning of yellow arc.

VNE

Never Exceed speed., 163 KIAS, red line

10° flaps

Max speed with 10° flaps; 110 KIAS.

10-30° flaps

Max speed with 10-30° flaps; 85 KIAS.

105 KIAS

Max speed at max takeoff weight; 105 KIAS for 2200 lb, 90 KIAS for 1900 lb.

White arc

Ends at 85 KIAS; indicates flap operating range.

End of green arc

Beginning of yellow arc.

Red line

Indicates 163 KIAS; never exceed speed.

Vx (Best Angle of Climb) definition

is the airspeed that gives the most altitude gain over the shortest horizontal distance, ideal for clearing obstacles like trees or buildings after takeoff

Vy (Best Rate of Climb) definition

gives the most altitude gain per unit of time, used for reaching cruising altitude quickly

Vglide, best glide speed

68 kias is the optimal airspeed for maximizing distance during a glide without power. It allows for the longest possible glide distance before landing, providing a balance between lift and drag.
