'''TASK 1030'''
'''PERFORM HOVER OUT-OF-GROUND EFFECT CHECK'''

'''CONDITIONS:''' In a UH-1 helicopter with hover out-of-ground effect (OGE) power available and
the aircraft heading into the wind.

'''STANDARDS:''' Appropriate common standards plus these additions/modifications:

1. Establish a hover altitude of 50 feet or above surrounding obstacles whichever is higher.

2. Determine if aircraft power and controllability are sufficient for maneuvers requiring OGE
hover power.

'''DESCRIPTION:''' The P* will announce his intent to ascend vertically to 50 feet or above
surrounding obstacles whichever is higher. The P* will remain focused outside the aircraft during the
entire maneuver to maintain obstacle clearance. The P* will execute a 360-degree left pedal turn. The
pilot not on the controls (P) will monitor the exhaust gas temperature (EGT), torque, and other
aircraft instruments, and the nonrated crewmember (NCM) will maintain airspace surveillance.
During the pedal turn, the P* will check the controllability of the aircraft. The P* will announce their
intent to descend vertically to an in-ground effect (IGE) hover or to the ground.

'''Note:''' Hover OGE power is required for this task.

'''Note:''' The crew should perform a hover OGE check anytime aircraft controllability or
available power is in doubt.

'''NIGHT OR NIGHT VISION GOGGLE CONSIDERATIONS:'''
1. The P* may have difficulty maintaining altitude and position when hovering above 25 feet.
(The barometric altimeter is not reliable for this maneuver.) If available, a radar altimeter should
be used to assist in maintaining a constant altitude. Otherwise, references such as lights, tops of
trees, or man-made objects above and to the front and sides of the aircraft should be used. By
establishing a reference angle to these objects, the P* can detect changes in altitude by changes in
their viewing perspective.

2. Hovering near ground features, such as roads, provides ideal references for judging lateral
movement. The P* may become spatially disoriented when changing viewing perspective back
and forth between high and low references. Therefore, the P* must rely on the P and NCM for
assistance in maintaining orientation.

3. When wearing NVG, the crew must select an area with good ground contrast and several
reference points at the same height, or at a greater height than the OGE hover. This will aid the
P* in maintaining a constant altitude and position over the ground while making the required
turns. The crew must use proper scanning techniques to ensure obstacle avoidance and tail rotor
clearance. To prevent inadvertent aircraft movement while hovering OGE, the P* will remain
focused outside the aircraft and the P will monitor all aircraft instruments.

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

'''REFERENCES:''' Appropriate common references.
