Next on our seaplane skills hit list were glassy water landings. While lots of wind makes for hazardous seaplane operations, so does no wind at all, because of the danger that glassy water poses. When the water is rippled, wind streaked or even a bit choppy, it's pretty easy to judge your distance above the surface. Not so with glassy water. The technique, in short, is to establish a landing attitude above the last visual reference, a tree, bush or buoy, and then hold that attitude until the floats contact the water, avoiding in the process the urge to judge your height visually. You don't try because, repeat after me, you can't tell. With truly glassy water, the bottom of the lake or bay, which may be 20 feet or more below the surface, can look like the surface as you set up to land. When conditions are like this, a pilot trying to judge the flare visually can fly the airplane floats low directly into the drink, seeking that illusionary surface, with predictably disastrous results. The key with glassy water is to not trust your instincts, relying instead on the technique. It's a skill that takes practice.
