What are the three portions of the aircraft that you must avoid at all times?

The correct answer identifies critical areas around the aircraft that pose significant risks to personnel on the ground. Understanding these areas is crucial for maintaining safety during operations.

The main rotor blade and tail rotor blade are both essential components of the aircraft's flight mechanism and can cause severe injury or fatality due to their high-speed rotation. The cargo hook, used for transporting loads, poses a risk as it can catch clothing or gear, creating a potential entanglement hazard when loads are being hooked up or released.

In aviation safety training, awareness of these particular areas is emphasized to prevent accidents. Proper situational awareness regarding the main rotor, tail rotor, and cargo hook helps ensure that personnel maintain a safe distance and protect themselves during flight operations. This knowledge is foundational in developing a mindset focused on safety in and around aircraft.
