e. Water surface/condition

ACS element text (the applicant demonstrates understanding of)

Effects of: e. Water surface/condition

Bottom line

At seaplane bases, conditions that allow for landing may not be sufficient for takeoff, and obstructions may exist below the water and could be affected by tides. Before landing, the pilot should consider the wind and surface conditions expected when it is time to leave. A beginner should not attempt to take off in rough water if the waves are too high.
