TASK 1058 PERFORM HOVERING FLIGHT
CONDITIONS: In a UH-1 helicopter.
STANDARDS: Appropriate common standards.
1. Crew actions.
a. The pilot on the controls (P*) will focus primarily outside the aircraft to provide obstacle clearance throughout the maneuver. The P* will announce when they begin the approach and whether the approach will terminate to a hover or to the surface. The P* also will announce the intended point of landing and any deviation to the approach to include go-around, if required.
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 and obstacles. The P and NCM will acknowledge any deviation during the approach. The P and NCM will announce when their attention is focused inside the aircraft and again when attention is reestablished outside.
2. Procedures. Evaluate winds. Select an approach angle that allows obstacle clearance while descending to the desired point of termination. Once the termination point is sighted and the approach angle is intercepted, adjust the collective as necessary to establish and maintain a constant angle. Maintain entry airspeed until the rate of closure appears to be increasing. Above 50-feet above ground level (AGL), maintain ground track alignment and the aircraft in trim.
Below 50-feet AGL, align the aircraft with the landing direction. Progressively decrease the rate of descent and rate of closure until reaching the termination point (hover, touchdown), or until a decision is made to perform a go-around.
a. To a hover. The approach to a hover may terminate with a full stop over the planned termination point, or continued movement to transition to hovering flight. Progressively decrease the rate of descent and rate of closure until an appropriate hover is established over the intended termination point.
b. To the surface. The decision to terminate to the surface with zero speed or with forward movement will depend on the aircraft's loading or environmental conditions. Touchdown with minimum lateral movement. After surface contact, ensure that the aircraft remains stable until all movement stops. Smoothly lower the collective to the full down position and neutralize the pedals and cyclic.
c. Go-around. This is a planned maneuver with the aircraft under control. The P* should perform a go-around if a successful landing is doubtful or if visual reference with the intended termination point is lost. Once climb is established, reassess the situation and develop a new course of action.
d. Escape route. This is an unplanned maneuver where in the aircraft may not be under complete control. Escape routes will normally be selected to the right-side of the approach path due to loss of tail rotor effectiveness (LTE) considerations.
Note: Performing this maneuver in certain environments may require hover out-of-ground effect (OGE) power. Evaluate each situation for power required versus power available.
Note: The P* should determine the torque required for the planned approach technique and announce the value to the P and NCM(s).
Note: A wind evaluation should be performed. Techniques for evaluating wind conditions are found in FM 1-202, Environmental Flight and appendix B of this ATM.
Note: Steep approaches can place the aircraft in potential settling-with-power conditions.

MUD/MUSKEG/TUNDRA CONSIDERATIONS: Select a suitable area and terminate the approach to a 3-foot hover over the intended touchdown point. Begin a vertical descent until the aircraft touches down. Check aircraft stability while lowering the collective. If the area is suitable, lower the collective to the full down position and neutralize the cyclic and pedals.
