Rough Water Takeoff and Climb (ASES, AMES)
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with rough water takeoff and climb. Note: If a rough water condition does not exist, the applicant must be evaluated by simulating the Task.
Bottom line
ROUGH WATER TAKEOFFS The objective in a rough water takeoff is similar to that of a rough or soft field takeoff in a landplane: to transfer the weight of the airplane to the wings as soon as possible, get airborne at a minimum airspeed, accelerate in ground effect to a safe climb speed, and climb out.
