Plowing Position Plowing Position

   When the power is increased significantly above idling, the seaplane will usually assume a nose up or "plowing" position (Fig. 15-4). Most seaplane experts do not recommend the plowing position for taxiing, except in rough water when it would be desirable to raise the propeller clear of the spray, or when turning the seaplane downwind during strong wind conditions. To attain this position, full power should be applied and the elevator control held in the full aft position. Sea planes that have a high thrust line will tend to nose down upon application of power, in which case it is imperative that the elevator control be held in the full aft position. The "plowing" position is brought about by the combination of the propeller slipstream striking the elevator and the hydrodynamic force of water exerted on the underside of the float's or hull's bow. After the planing position is attained, the power should be reduced to maintain the proper speed.

   If the water conditions are favorable and there is a long distance to travel, the seaplane may be taxied at high speed "on the step." This position (Fig. 15-4) is reached by accelerating the seaplane to the degree that it passes through the plowing phase until the floats or hull are literally riding on the water in a level position.
