What speed should a pilot aim for when flying without power and with flaps extended?

When flying without power and with flaps extended in a Cessna 152, the correct speed to aim for is 55 KIAS (Knots Indicated Airspeed). This speed is important as it allows for a stable and controlled descent. When the flaps are extended, the aircraft's stall speed increases, but flying at 55 KIAS provides a good margin above stall speed while maintaining controlled airflow over the wings.

This speed facilitates effective control of the aircraft's descent rate and allows for adequate lift, which is especially crucial during simulated emergency descents or when performing power-off landings. Aiming for this speed also helps in achieving the best glide performance for the aircraft configuration, maximizing lift while minimizing drag.
