  1. CONDITIONS: In an OH-58D helicopter and aircraft cleared.

  2. STANDARDS: Appropriate common standards plus the following.

    1. Perform a smooth, controlled ascent to hover.

    2. Perform a smooth, controlled descent with minimal drift at touchdown.

    1. Crew actions.

          1. The P* will announce his intent to perform a specific hovering flight maneuver and will remain focused outside the aircraft. He will announce when the he terminates the maneuver.

          2. The P will assist in clearing the aircraft and will provide adequate warning of obstacles and unannounced or unusual drift/altitude changes. He will announce when his attention is focused inside the cockpit and again when his attention is outside.

    2. Procedures. Control heading, direction of turn and rate of turn with the pedals. Control altitude, rate of ascent and rate of descent with the collective. Control position and direction of movement with cyclic.

          1. Takeoff to a hover. With the collective full down, place the cyclic in a neutral position. Increase the collective, apply pedals as necessary to maintain heading, and coordinate the cyclic for a vertical ascent. As the aircraft leaves the ground, check for proper control response and aircraft CG. Upon reaching the desired hover altitude adjust the flight controls to maintain position over the intended hover point. If sloping conditions are suspected, see Task 1062, Perform slope operations.

          2. Hovering flight. Adjust the cyclic to maintain a stationary hover or to move in the desired direction. Control heading with pedals, and maintain altitude with the collec­tive. Maintain a constant hover speed. To return to a station­ary hover, apply the cyclic in the opposite direction while maintaining altitude with collective and heading with the pedals.

          3. Hovering turns. Clear the aircraft. Apply pressure to the desired pedal to begin the turn. Use pressure and counter pressure on the pedals to maintain a constant rate of turn. Coordinate cyclic to maintain posi­tion over the pivot point while maintaining altitude with the collective. (Hovering turns can be made around the vertical axis, nose, or tail of the aircraft.)

          4. Landing from a hover. From a stationary hover, lower the collective to effect a smooth descent to touchdown. Make necessary corrections with the pedals and cyclic to maintain a constant heading and position. On ground contact, ensure that the aircraft remains stable (If uneven surface conditions are suspected use pedals to perform a suitability check prior to lowering the collective full down). Continue decreasing the collective smoothly and steadily until the entire weight of the aircraft is on the ground. Neutralize the pedals and cyclic, and reduce the collective to the fully down position.
  4. NIGHT OR NVG CONSIDERATIONS: Movement over areas of limited contrast, such as tall grass, water, or desert, tends to cause spatial disorientation. To avoid spatial disorientation, seek hover areas that provide adequate contrast and use proper scan­ning techniques. If disorientation occurs, apply sufficient power and execute a takeoff. If a takeoff is not feasible, try to maneuver the aircraft forward and down to the ground to limit the possibility of touchdown with sideward or rearward movement. Maintain a proper scanning technique to avoid spatial disorientation.

  5. SNOW/SAND/DUST CONSIDERATIONS: During ascent to a hover, if visual references deteriorate to an unacceptable level, continue ascend to a hover altitude above the blowing conditions. The P should keep the P* informed of the location of the snow/sand/dust cloud.

    1. 10-foot hover taxi. During takeoff to a hover, simultaneously accelerate the aircraft to a ground speed that keeps the snow/sand/dust cloud behind the main rotor mast. Maintain optimum visibility by observing references close to the aircraft. Exercise caution when operating in close proximity to other aircraft or obstacles.

  1. When visual references deteriorate making a 10-foot hover taxi unsafe, determine whether to abort the maneuver, ground taxi, air taxi, or perform a takeoff.

    1. 20 to 100-foot air taxi. Use this maneuver when it is necessary to move the aircraft over terrain that is unsuitable for hover taxi. Initiate air taxi the same as for a 10-foot hover, but increase altitude to not more than 100 feet and accelerate to a safe airspeed above ETL. Ensure that an area is available to safely decelerate and land the aircraft. Under certain conditions (for example, adverse winds), it may be necessary to perform a traffic pattern to optimize conditions at the desired termination point.

  1. Hovering OGE reduces available ground references and may increase the possibility of spatial disorientation. Be prepared to transition to instruments and execute and instrument takeoff if ground reference is lost.

  2. At night, use of the search light may cause spatial disorientation while in blowing snow/sand/dust.

  3. Consider the effects of the snow/sand/dust cloud on personnel and equipment in/around the landing area.
  1. CONFINED AREA CONSIDERATIONS: Select good references to avoid unanticipated drift. All crewmembers must be focused primarily outside for obstacle avoidance.


    1. Training. Training will be conducted in the aircraft. The normal height for IGE hover is 3 feet. The normal height for OGE hover is 50 feet or greater.

    2. Evaluation. Evaluation will be conducted in the aircraft. The normal height for IGE hover is 3 feet. The normal height for OGE hover is 50 feet or greater.
