Purpose: To land from a hover and takeoff to a hover from a sloping surface.
Note: Prior to conducting slope operations, the pilot will review Robinson Safety Notice SN-9 and become thoroughly familiar with dynamic roll-over characteristics. For training purposes, use a maximum slope angle of 5 degrees.
- Approach the slope at a 45 degree angle.
- Clear the area.
- Into the wind, in a 3 foot hover, stabilize the aircraft parallel to the slope.
- Smoothly and slowly begin to lower the collective to establish a slow rate of sink.
- When the upslope skid contacts the ground, begin applying lateral cyclic into the slope to hold the skid into the slope.
- Stabilize the helicopter in a one skid hover before continuing.
- Continue slowly lowering the collective while hold the upslope skid in the slope until the downslope skid is firmly on the ground.
Note: If full cyclic travel is reached prior to the downslope skid’s making contact with the ground, abort the maneuver.
- Once the skids are on the ground, slowly lower the collective, and then center all the controls.
The procedure for slope takeoff is almost the exact reverse of that for a slope landing.
Ensure skids of the aircraft are clear.
- Apply cyclic into the slope. Slowly begin to increase collective.
- As the helicopter becomes light on the skids, pause and neutralize any aircraft movement.
- Maintain heading with pedals.
- When the down slope skid breaks ground, slowly begin to center the cyclic.
- As a level attitude is reached, the cyclic should be neutral.
- Continue to increase collective while maintaining position until in a 3 ft hover.
- Slowly move the helicopter laterally away from the landing spot to ensure clearance for tail rotor.
Never turn the tail rotor towards the slope.
