What is the proper procedure for a slope landing in a helicopter with skid-type landing gear?

The correct procedure for landing a helicopter with skid-type landing gear on a slope involves careful attention to the orientation of the skids in relation to the slope. Lowering the un-slope skid first when the helicopter is parallel to the slope allows for a controlled and stable landing. This technique helps ensure that the helicopter maintains its balance on the slope, reducing the risk of rolling or tipping over once the down-slope skid is lowered.

By first securing the un-slope skid to the ground, the helicopter has a stable pivot point, allowing the pilot to then lower the down-slope skid safely. This method is critical in maintaining control during landing, especially on uneven surfaces or inclines.

In contrast, landing with an abrupt descent is hazardous as it can lead to a sudden drop that compromises stability. Slowly lowering the down-slope skid first does not provide the necessary stability and control needed on a slope. Meanwhile, skidding across the slope can cause the helicopter to slide uncontrollably, increasing the risk of an accident. The correct technique thus emphasizes a methodical and controlled approach to landing on slopes.
