Which areas are considered danger zones of the aircraft?

Tail rotors are considered danger zones on an aircraft, particularly in helicopters, because they produce significant rotational forces that can cause serious injury or damage to personnel who inadvertently enter their effective range. The tail rotor's primary function is to counteract the torque produced by the main rotor and maintain directional control during flight.

When the tail rotor is spinning, its blades create a hazardous environment, especially when a person is close enough to come within the rotor's path. Special training and awareness are required for ground crew members to ensure they maintain a safe distance and understand the risks associated with operating around a helicopter.

In contrast, while engines, propellers, and cargo doors do present hazards, the unique characteristics of the tail rotor, such as its placement and high speed, particularly emphasize its dangerous nature. Each of these components must be treated with care, but the tail rotor stands out due to the specific risks associated with its operation in flight and on the ground.
