Porpoising and skipping.

ACS element text (the applicant demonstrates understanding of)

Porpoising and skipping.

Bottom line

Skipping is a form of instability that may occur when landing at excessive speed with the nose at too high a pitch angle. If porpoising occurs due to a nose-low planing attitude, stop it by applying timely back pressure on the elevator control to prevent the bows of the floats from digging into the water.
