CA.IV.EFAA-S-ACS-7B · Nov 2023

Short-Field Takeoff and Maximum Performance Climb (ASEL, AMEL)

ACS task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with short-field takeoff, maximum performance climb operations, and rejected takeoff procedures.

Bottom line

A good use of maximum AOC is when taking off from a short airfield surrounded by high obstacles, such as trees or power lines.
