What is the recommended airspeed for a precautionary landing with engine power?

The recommended airspeed of 55 KIAS for a precautionary landing with engine power is particularly important for maintaining control and ensuring a safe descent. This speed enables the pilot to achieve a balance between lift and drag, ensuring that the aircraft remains within a safe margin of airspeed while also allowing for effective maneuverability.

Airspeed is critical in any landing scenario, especially during a precautionary landing where the pilot may need to maneuver for the best approach or to avoid obstacles. At 55 KIAS, the Cessna 152 provides a stable platform, and this airspeed is close to the aircraft's best glide ratio while still retaining sufficient control authority and responsiveness.

Lower airspeeds could lead to a stall, reducing the safety margin during the landing process. Conversely, higher speeds could lead to overshooting the intended landing zone or encountering issues with control and braking upon landing. Thus, 55 KIAS is the optimal airspeed for managing these variables effectively while executing a precautionary landing.
