What is the best climb airspeed during a soft field takeoff?

During a soft field takeoff, the best climb airspeed is crucial for ensuring the aircraft can clear any obstacles while maintaining control. The indicated airspeed that allows for the best climb performance is typically the one that provides optimal lift while minimizing drag.

For many light aircraft, the best climb speed in this scenario often aligns with the aircraft's maneuvering speed and is usually slightly below the stall speed. In the case of a soft field takeoff, pilots will want to maintain a slightly lower airspeed to allow for a gentle climb and to ensure maximum lift is generated at the most effective angle of attack.

56 KIAS is representative of a speed that allows the aircraft to maintain a safe margin above stall while also providing sufficient lift needed for the climb in conditions that may be less than ideal, such as when taking off from soft or muddy surfaces. It is advisable to establish this airspeed as soon as safely possible after takeoff to maximize climb performance and obstacle clearance effectiveness, especially in more challenging takeoff environments.

The other speeds listed may be higher than necessary for a soft field takeoff, which could result in a less efficient climb or a higher stall risk in nuanced conditions.
