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
The takeoff technique is identical to a normal takeoff until the seaplane is on the step and nearly at flying speed. Once the seaplane lifts off, establish a positive rate of climb to prevent inadvertently flying back into the water.
