What is the maximum slope allowed for a landing zone?

The maximum slope allowed for a landing zone is 5%. This standard is in place to ensure the safety and stability of helicopters during landing and takeoff operations. A slope steeper than 5% can create challenges for pilots as they maneuver to land safely, increasing the risk of accidents. Maintaining a slope of 5% or less assists in providing a consistent and reliable surface that helps stabilize the aircraft and minimizes the potential for it to shift or slide, which could compromise the safety of both the crew and any personnel on the ground.
