extract: TC 1-211 AIRCREW TRAINING MANUAL UTILITY HELICOPTER, UH-1H/V SERIES TASK 1038 PERFORM HOVERING FLIGHT CONDITIONS: In a UH-1 helicopter. STANDARDS: Appropriate common standards. DESCRIPTION: 1. Crew actions. a. The pilot on the controls (P*) will announce their intent to perform a specific hovering flight maneuver and will remain focused primarily outside the aircraft to monitor altitude and avoid obstacles. The P* will ensure and announce that the aircraft is cleared prior to turning or repositioning the aircraft. The P* will announce terminating the maneuver. b. The pilot not on the controls (P) and nonrated crewmember (NCM) will assist in clearing the aircraft and provide adequate warning of obstacles, unannounced drift, or altitude changes. They will announce when their attention is focused inside the aircraft and again when attention is reestablished outside. 2. Procedures. a. Takeoff to a hover. With the collective full down, place the cyclic in a neutral position. Increase the collective smoothly. Apply pedals to maintain heading, and coordinate the cyclic for a vertical ascent. As the aircraft leaves the ground, check for the proper control response and aircraft center of gravity (CG). Continue to increase collective for a smooth, controlled ascent to a hover. b. Hovering flight. Adjust the cyclic to maintain a stationary hover or to move in the desired direction. Control heading with the pedals, and maintain altitude with the collective. The rate of movement and altitude should be appropriate for existing conditions. To return to a stationary hover, apply cyclic in the opposite direction while maintaining altitude with the collective and heading with the pedals. Note: Air taxi is the preferred method for ground movements on airports provided ground operations and conditions permit. Unless otherwise requested or instructed, pilots are expected to remain below 100 feet above ground level (AGL). However, if a higher than normal airspeed or altitude is desired, the request should be made prior to lift-off. The pilot is solely responsible for selecting a safe airspeed for the altitude/operation being conducted. Use of air taxi enables the pilot to proceed at an optimum airspeed/altitude, minimize down wash effect, conserve fuel, and expedite movement from one point to another. c. Hovering turns. Apply pressure to the desired pedal to begin the turn. Use pressure and counter pressure on the pedals to maintain the desired rate of turn. Coordinate cyclic control to maintain position over the pivot point while maintaining altitude with the collective. Hovering turns can be made around any vertical axis; for example, the nose, mast, tail of the aircraft, or a point in front of the aircraft. However, turns other than about the center of the aircraft will increase the turn radius proportionately. d. Landing from a hover. Lower the collective to affect a smooth, controlled descent with minimal drift at touchdown. Ensure the aircraft does not move laterally or aft. Make necessary corrections with the pedals and cyclic to maintain a constant heading and position. On ground contact, ensure that the aircraft remains stable. Continue lowering the collective smoothly and steadily while continuing to check aircraft stability. When the collective is fully down, neutralize the pedals and cyclic. If sloping conditions are suspected or anticipated, (see Task 1062). Note: Cyclic turns should only be used when necessary. Note: When landing from a hover to an unimproved area, the crew must check for obstacles under the aircraft. NIGHT OR NIGHT VISION GOGGLE CONSIDERATIONS: 1. Movement over areas of limited contrast, such as tall grass, water, or desert, tends to cause 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. 2. When performing operations during unaided night flight, ensure that the searchlight or landing light (white light) is in the desired position. Use of the white light will impair night vision for several minutes. Therefore, exercise added caution if resuming flight before reaching full dark adaptation. SNOW/SAND/DUST CONSIDERATIONS: During ascent to a hover, if visual references do not deteriorate to an unacceptable level, continue ascent to the desired hover altitude. 1. The 3 to 5-foot hover taxi. During takeoff to a hover, simultaneously accelerate the aircraft to a ground speed that keeps the snow/sand/dust cloud just aft of the main rotor mast. Note: Maintain optimum visibility by observing references close to the aircraft. Exercise caution when operating in close proximity to other aircraft or obstacles. Note: When visual references deteriorate making a 3-foot hover taxi unsafe, determine whether to abort the maneuver, air taxi, or perform an instrument takeoff (ITO) (Task 1170). 2. The 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 a 3-foot hover, but increase altitude to not more than 100 feet and accelerate to a safe airspeed appropriate for conditions, above effective translational lift (ETL). Note: Ensure that an area is available to safely decelerate and land the aircraft. Under certain conditions, such as adverse winds, it may be necessary to perform a traffic pattern to optimize conditions at the desired termination point. Note: Hovering out-of-ground effect (OGE) reduces available ground references and may increase the possibility of spatial disorientation. Be prepared to transition to instruments and execute an instrument takeoff (ITO) (Task 1170) or unusual attitude recovery (Task 1182) if ground reference is lost. Note: At night, use of landing, search, or anti-collision light may cause spatial disorientation while in blowing snow/sand/dust. Note: OGE power may be required for this maneuver. CONFINED AREA CONSIDERATIONS: Select good references to avoid unanticipated drift. All crewmembers must be focused primarily outside for obstacle avoidance. TRAINING AND EVALUATION REQUIREMENTS: 1. Training will be conducted in the aircraft. 2. Evaluation will be conducted in the aircraft. REFERENCES: Appropriate common references.
