備註4) Glassy Water Landings Can Be Deadly
You may look at the glassy surface of a lake and think it must be perfect for flying a seaplane into. However, glassy water landings are actually the most dangerous maneuver you'll fly as a seaplane pilot. With no visual depth perception, it can be difficult to tell your height above the water.Seaplane pilots pick an aiming point and a last visual reference, sometimes the shoreline. Between the aiming point and last visual reference, you must establish yourself in a landing attitude, configuration, and specific power setting for descent. Then you wait for touching down on the water, always maintaining the same attitude and power setting. You don't use your vertical speed indicator (VSI), because it's a lag-instrument and only shows trends initially. If you're not established in your configuration by the last visual reference, you go-around.
