SkillDescribe how to correct for porpoising and skipping.

- SKIPPING
SKIPPING Skipping is a form of instability that may occur when landing at excessive speed with the nose at too high a pitch angle. This nose-up attitude places the seaplane at the upper trim limit of stability and causes ... seaplane to enter a cyclic oscillation when touching the water, which results in the seaplane skipping across the surface. This action is similar to skipping flat stones across the water. Skipping can also occur by crossing a boat wake while…

Cold Temperature Airport Procedures a. PILOTS MUST NOT MAKE AN ALTIMETER CHANGE to accomplish an altitude correction. Pilots must ensure that the altimeter is set to the current altimeter setting provided by ATC in accordance with ... Actions on when and where to make corrections: Pilots will make an altitude correction to the published, “at”, “at or above”, and “at or below” altitudes on all designated segment(s) to all runways for all published instrument approach procedures…
- TAXIING AND SAILING › PORPOISING
Usually, porpoising does not start until the seaplane has passed a degree or two beyond the acceptable planing angle range, and does not cease until after the seaplane has passed out of the critical range by a degree ... Figure 4-13. Porpoising increases in amplitude if not corrected promptly. 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…
