extract: TC 1-211 AIRCREW TRAINING MANUAL UTILITY HELICOPTER, UH-1H/V SERIES TASK 1066 PERFORM A RUNNING LANDING CONDITIONS: In a UH-1 helicopter with the before-landing check complete. STANDARDS: Appropriate common standards plus these additions/modifications: 1. Select a suitable landing area. 2. Maintain ground track alignment with the landing direction. 3. Maintain a constant approach angle clear of obstacles to desired touchdown point. 4. Touchdown aligned with landing direction ± 5 degrees, at/slightly above effective translational lift (ETL). DESCRIPTION: 1. Crew actions. a. The pilot on the controls (P*) will remain focused outside the aircraft to clear the aircraft throughout the approach and landing. The P* will announce the intended point of landing and any deviation from the approach. b. The pilot not on the controls (P) and nonrated crewmember (NCM) will confirm the suitability of the area, assist in clearing the aircraft, and provide adequate warning of traffic or obstacles. They will announce when their attention is focused inside the aircraft. 2. Procedure. a. Determine a shallow approach angle that allows safe obstacle clearance to arrive at the intended point of landing. Once the approach angle is intercepted, adjust the collective as necessary to establish and maintain the angle. Maintain entry airspeed until apparent ground speed and rate of closure appear to be increasing. Maintain ground track alignment with the landing direction by maintaining the aircraft in trim above 50 feet above ground level (AGL) and aligning the aircraft with the landing direction below 50 feet AGL. Control the rate of descent at touchdown with the collective. Maintain aircraft attitude and landing alignment with the cyclic and heading with the pedals. The touchdown speed may vary from ETL to slightly above ETL as dictated by landing area conditions. b. After ground contact, ensure the aircraft remains stable as the collective is lowered to reduce ground run. Once the aircraft has come to a complete stop, reduce the collective to the fully down position and neutralize the pedals and cyclic. Note: This maneuver may be performed in an environment where obscurants (for example, sand, dust, or snow) are present. NIGHT OR NIGHT VISION GOGGLE CONSIDERATIONS: 1. Altitude, apparent ground speed, and rate of closure are difficult to estimate at night. The rate of descent during the final 100 feet should be slightly less at night than during the day to avoid abrupt attitude changes at low altitudes. 2. After establishing the descent during unaided flights, airspeed may be reduced to approximately 50 knots until apparent ground speed and rate of closure appear to be increasing. Progressively decrease the rate of decent and forward speed until termination of maneuver. 3. Surrounding terrain or vegetation may decrease contrast and cause degraded depth perception during the approach. Before descending below obstacles, determine the need for artificial lighting. 4. 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 may impair night vision for several minutes. Therefore, exercise added caution if resuming flight before reaching full dark adaptation. ROUGH/UNPREPARED SURFACE CONSIDERATIONS: Closely monitor touchdown speed when landing to a rough or unprepared surface. If the surface is soft, exercise care when lowering the collective until the aircraft comes to a complete stop. TRAINING AND EVALUATION REQUIREMENTS: 1. Training will be conducted in the aircraft. 2. The evaluation will be conducted in the aircraft. REFERENCES: Appropriate common references.
