From which angle should personnel approach a helicopter?

When approaching a helicopter, it is crucial to do so from the sides. This is primarily to maintain visibility to the pilots and avoid the main rotor blades, which can pose a significant hazard. Helicopters are designed with their rotor systems positioned above and around the aircraft, and the most dangerous areas are directly in front of and behind the helicopter. By approaching from the sides, personnel can minimize the risk of collision with the rotor blades and maintain awareness of the helicopter's operations and the crew's movements inside. This approach technique is standard procedure to ensure safety during operations involving helicopters.
