- LANDING › DOWNWIND LANDING
DOWNWIND LANDING Although downwind landings often require significantly more water area, there are occasions when they are more convenient or even safer than landing into the wind. Sometimes landing upwind would mean a long, slow taxi ... back along the landing path to get to the dock or mooring area. If winds are less than 5 knots and there is ample room, landing downwind could save taxi time. Unless the winds are light, a downwind…

alters the landing speed or deceleration rate during the landing roll affects the landing distance. The effect of gross weight on landing distance is one of the principal items determining the landing distance. One effect ... required to support the aircraft at the landing AOA and lift coefficient. For an example of the effect of a change in gross weight, a 21 percent increase in landing weight requires a ten percent increase in landing…
- LANDING › CROSSWIND LANDING
Directional control can be more difficult on water because the surface is more yielding, there is less surface friction than on land, and seaplanes lack brakes. These factors increase the seaplane’s tendency to weathervane into the wind ... technique sometimes used to compensate for crosswinds during water operations is the same as that used on land; that is, by lowering the upwind wing while holding a straight course with rudder. This creates a slip into the wind…
- LANDING › CONFINED AREA LANDING
pitching and rolling produced by the water motion increases the likelihood of the wind lifting a wing and flipping the seaplane. There is additional information on rough water landings in Chapter 8, Emergency Open Sea Operations. CONFINED AREA LANDING One of the first concerns when considering a landing in a confined area is whether it is possible to get out again. For most seaplanes, the takeoff run is usually much longer than the landing run. Before…
- LANDING AREA RECONNAISSANCE AND PLANNING
When a swell system is superimposed on a second swell system, some of the waves may reinforce each other, resulting in higher waves, while other waves cancel each other out, leaving smoother areas. Often it is possible to avoid ... larger waves and land on the smooth areas. In seaplanes equipped with retractable landing gear (amphibians), it is extremely important to make certain that the wheels are retracted when landing on water. Wherever possible, make a visual…

landing spot. In general, make the touchdown at a somewhat flatter pitch attitude than usual. This prevents the seaplane from being tossed back into the air at a dangerously low airspeed, and helps the floats to slice through ... tops of the waves rather than slamming hard against them. Reduce power as the seaplane settles into the water, and apply back pressure as it comes off the step to keep the float bows from digging into a wave face…
