Soft-Field Takeoff and Climb (ASEL)
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with soft-field takeoff, climb operations, and rejected takeoff procedures.
Bottom line
Ground effect is a factor in every landing and every takeoff in fixed-wing airplanes. If during a soft-field takeoff and climb, for example, the pilot attempts to climb out of ground effect without first attaining normal climb pitch attitude and airspeed, the airplane may inadvertently enter the region of reversed command at a dangerously low altitude. The manufacturer’s recommended takeoff speed is necessary to provide adequate initial climb performance.
