The Cessna 152 stalls at different speeds depending on its configuration, primarily 40 Knots Indicated Airspeed (KIAS) in a landing configuration and 50 KIAS in a cruise configuration.
A stall occurs when the airflow over the wing separates, leading to a significant loss of lift. The speed at which this happens is influenced by various factors, most notably the aircraft's configuration and weight. For the Cessna 152, two primary stall speeds are recognized:
- Vso (Stall Speed in Landing Configuration): This refers to the stall speed when the aircraft is configured for landing, typically with full flaps extended. The increased lift and drag generated by the flaps allow the aircraft to fly at a slower speed without stalling.
- Vs1 (Stall Speed in Clean or Cruise Configuration): This is the stall speed when the aircraft is in its "clean" configuration, meaning flaps are retracted. Without the additional lift provided by extended flaps, a higher airspeed is required to maintain flight.
Cessna 152 Stall Speeds
Understanding these distinct stall speeds is crucial for pilots to ensure safe flight operations across different phases of flight.
| Stall Configuration | Speed (KIAS) |
|---|---|
| In Landing Configuration | 40 |
| In Cruise Configuration | 50 |
The 40 KIAS (Vso) stall speed is particularly important during the approach and landing phases, allowing for a slower, controlled descent. Conversely, the 50 KIAS (Vs1) stall speed is relevant for normal cruise flight or climbing maneuvers where the aircraft is in its most aerodynamically efficient configuration.
