During slope landing, what should the pilot do when parallel to the slope?

In the context of slope landing, the appropriate technique is to lower the upslope skid before the downslope skid. This method helps to ensure that the aircraft maintains stability and control as it lands on an inclined surface. By lowering the upslope skid first, the pilot sets the aircraft in a position that allows for a smoother transition onto the slope, helping to prevent the aircraft from tipping over or becoming unstable due to the uneven terrain.

This practice is crucial because it allows the weight of the helicopter to be distributed evenly, reducing the risk of losing control once the aircraft makes contact with the ground. This technique enhances safety during landing, especially on challenging terrains that can introduce additional factors influencing the aircraft's behavior during the landing phase. Overall, it ensures that both skids make adequate contact with the slope in a controlled manner, significantly contributing to a successful landing on a slope.
