TASK 2036

Exract: TC 1-211 AIRCREW TRAINING MANUAL UTILITY HELICOPTER, UH-1H/V SERIES

TASK 2036
PERFORM TERRAIN FLIGHT DECELERATION

CONDITIONS: In a UH-1 helicopter.

STANDARDS: Appropriate common standards plus these additions/modifications:
1. Maintain heading alignment with the selected flight path.
2. Maintain the tail clear of all obstacles.
3. Decelerate to the desired airspeed or to a full stop.

DESCRIPTION:
1. Crew actions.

 a. The pilot on the controls (P*) will focus primarily outside the aircraft to clear the aircraft
 throughout the maneuver. The P* will announce any intention to decelerate or come to a full
 stop, any deviation from the maneuver, and completion of the maneuver.
 
 b. The pilot not on the controls (P) and nonrated crewmember (NCM) will provide adequate
 warning to avoid obstacles detected in the flight path and will announce when their attention
 is focused inside the cockpit and again when attention is reestablished outside.

2. Procedures.

 a. Coordinate application of cyclic and collective to establish a decelerative attitude that
 keeps the tail clear of all obstacles. Consider variations in the terrain and obstacles when
 determining tail clearance. Apply aft cyclic as required to slow to the desired airspeed or to a
 full stop while adjusting the collective to maintain the altitude of the tail. Maintain heading
 and make all control movements smoothly.
 
 b. If the aircraft attitude is changed excessively or abruptly, it may be difficult to return the
 aircraft to a level attitude and overcontrolling may result.

Note: Hover out-of-ground effect (OGE) power is required for this maneuver.

NIGHT OR NIGHT VISION GOGGLE CONSIDERATIONS:
1. Because of the limited field of view of the NVG, avoid making abrupt changes in aircraft
attitude. An extreme nose-high attitude limits the forward field of view.
2. Maintain proper scanning techniques to ensure obstacle avoidance and tail rotor clearance.

TRAINING AND EVALUATION REQUIREMENTS:
1. Training will be conducted in the aircraft.
2. Evaluation will be conducted in the aircraft.
