Control pressures and direction of application change continuously throughout the turn. The most dramatic change is the pedal pressure (and corresponding power requirement) necessary to control the rate of turn as the helicopter moves through the downwind portion of the maneuver. Turns can be made in either direction; however, in a high wind condition, the tail rotor may not be able to produce enough thrust, which means you will not be able to control a turn to the right in a counterclockwise rotor system. Therefore, if control is ever question- able, you should first attempt to make a 90° turn to the left. If sufficient tail rotor thrust exists to turn the helicopter crosswind in a left turn, a right turn can be successfully controlled. The opposite applies to helicopters with clockwise rotor systems. In this case, you should start your turn to the right. Hovering turns should be avoided in winds strong enough to preclude sufficient aft cyclic control to maintain the helicopter on the selected surface reference point when headed downwind. Check the flight manual for the manufacturer’s recom- mendations for this limitation. pedals, altitude with the collective, and the proper r.p.m. with the throttle. To stop the forward movement, apply reward cyclic pressure until the helicopter stops. As forward motion stops, return the cyclic to the neutral position to pre- vent rearward movement. Forward movement can also be stopped by simply applying rearward pressure to level the helicopter and let it drift to a stop. You normally use forward hovering flight to move a  helicopter to a specific location, and it is usually begun from a stationary hover. During the maneuver, constant groundspeed, altitude, and heading should be maintained. Before starting, pick out two references directly in front and in line with the helicopter. These reference points should be kept in line throughout the maneuver. [Figure 9-3] Sideward hovering flight may be necessary to move the helicopter to a specific area when conditions make it impossible to use forward flight. During the maneu- ver, a constant groundspeed, altitude, and heading should be maintained. Before starting sideward hovering flight, make sure the area you are going to hover into is clear. Then pick two points of reference in a line in the direction of sideward hovering flight to help you maintain the proper ground Begin the maneuver from a normal hovering altitude by applying forward pressure on the cyclic. As movement begins, return the cyclic toward the neutral position to keep the groundspeed at a slow rate—no faster than a brisk walk. Throughout the maneuver, maintain a constant groundspeed and path over the ground with the cyclic, a constant heading with the antitorque 9-7 TECHNIQUE HOVERING—SIDEWARD FLIGHT TECHNIQUE HOVERING—FORWARD FLIGHT COMMON ERRORS COMMON ERRORS Figure 9-3. To maintain a straight ground track, use two refer- ence points in line and at some distance in front of the helicopter. 1. Failing to maintain a slow, constant rate of turn. 2. Failing to maintain position over the reference point. 3. Failing to maintain r.p.m. within normal range. 4. Failing to maintain constant altitude. 5. Failing to use the antitorque pedals properly. 1. Exaggerated movement of the cyclic, resulting in erratic movement over the surface. 2. Failure to use the antitorque pedals properly, resulting is excessive heading changes. 3. Failure to maintain desired hovering altitude. 4. Failure to maintain proper r.p.m. ReferenceGLYPH<.notdef> Points
