SkillDescribe how to correct for porpoising and skipping.
From the FAA library
- 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…
- 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…

thru 7-3-5e when complying with the baro-VNAV temperature note on an RNAV (GPS) approach. Correction is not required nor expected to be applied to procedure altitudes or VNAV paths outside of the final approach segment ... Operators must advise ATC when making temperature corrections on RNP authorization required (AR) approaches while adhering to baro-VNAV temperature note. 3. Reporting altitude corrections is required when complying with CTAs in conjunction with the baro-VNAV temperature note…

correction calculated from the table for the MDA or DA may be used as is or rounded up, but never rounded down. This number will be added to the MDA, DA, and all step-down fix altitudes inside ... column is required. Pilots may use the 5000 ft “height above airport in feet” column for calculating corrections when the calculated altitude is greater than 5000 ft above reporting station elevation. Pilots must add the correction(s) from the table…

wing, both wingtips should be level and equally above or below the natural horizon. Any necessary bank corrections are made with the pilot’s coordinated use of ailerons and rudder. [Figure 3-7] The pilot should understand that anytime ... wings are banked, the airplane turns. The objective of straight flight is to detect and correct small deviations, necessitating minor flight control corrections. The bank attitude information can also be obtained from a quick scan of the attitude indicator (which…
