Study Notes
V-Speeds of Cessna 152
- Vso (Stall Speed in Landing Configuration): 35 kias with flaps fully extended (30°).
- Vs (Stall Speed in Clean Configuration): 40 kias with flaps retracted (0°).
- Vr (Rotate Speed): 50 kias, the speed to initiate climb during takeoff.
- Vx (Best Angle of Climb): 54 kias; optimal for maximum altitude gained over distance (important when reaching runway end).
- Vy (Best Rate of Climb): 67 kias; ideal for maximum altitude gained over time (useful for short duration climbs).
- Vg (Best Glide Speed): 60 kias; maximizes glide distance in case of engine failure.
- Vfe (Maximum Flap Extension Speed): 85 kias; exceeding this could damage the flap system.
- Va (Maneuvering Speed): Ranges from 93 to 104 kias, depending on weight (104 kias at 1670 lbs, 93 kias at 1350 lbs). Fly at or below this in turbulence to prevent structural damage.
- Vno (Maximum Structural Cruising Speed): 111 kias; exceed only in smooth air with caution.
- Vne (Never Exceed Speed): 149 kias; crossing this limit can cause structural failure, such as wings detaching.
Airspeed Indicator (ASI) Depictions
- Flap Operating Range: Shown by a white arc on the ASI.
- Normal Operating Range: Indicated by the green arc on the ASI.
- Cautionary Range: Represented by the yellow arc on the ASI.
- Vno Location: Positioned at the bottom of the yellow arc/top of the green arc (actual Vno = 111).
- Vne Depiction: Clearly indicated by a red line on the ASI.
