Glassy Water Takeoff and Climb (ASES, AMES)
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with glassy water takeoff and climb. Note: If a glassy water condition does not exist, the applicant must be evaluated by simulating the Task.
Bottom line
Once airborne, the lack of visual cues to the seaplane’s height above the water can create a potentially dangerous situation unless a positive rate of climb is maintained. Once the seaplane lifts off, establish a positive rate of climb to prevent inadvertently flying back into the water.
