Which procedure is indicated by using an airspeed of 55 KIAS?

Using an airspeed of 55 KIAS (Knots Indicated Airspeed) is indicative of landing without power with flaps down in the Cessna 152. This airspeed aligns with the recommended configuration for a stable approach when conducting a no-power landing, which involves maximizing lift and maintaining control during the descent.

In this scenario, deploying flaps increases the aircraft’s lift at lower speeds, allowing for a more controlled and gradual descent. This approach aids in safely managing the aircraft as it reaches the ground, enhancing the chances of a smooth landing, especially in a no-power situation.

The other scenarios presented do not typically utilize this specific airspeed for their procedures. For a precautionary landing with engine power, a higher speed would generally be maintained to ensure a safe and controlled approach, whereas maximum glide for emergency procedures would require airspeed management that focuses on best glide rather than a fixed approach speed, which would be higher than 55 KIAS for the Cessna 152. Additionally, landing without power with flaps up would generally be executed at a higher airspeed to ensure better control and lift capability.
