What is the purpose of clearing loose debris in a helicopter landing zone?

Clearing loose debris in a helicopter landing zone is primarily aimed at ensuring the safety of personnel and equipment. Debris such as branches, rocks, or loose gravel can pose significant hazards during landings and takeoffs. If debris is not cleared, it can be ingested into the helicopter's rotor blades or engine, leading to potential mechanical failures, accidents, or injuries to personnel on the ground.

This safety measure protects not only the helicopter and its occupants but also any individuals nearby who may be in the vicinity during landing maneuvers. Maintaining a clean landing zone minimizes the risk of accidents and ensures a smooth operation, which is crucial for emergency responses and other critical missions involving helicopters.
