Final answer:
The correct safety procedure for embarking and exiting a helicopter includes waiting for the pilot's signal and instructions, keeping your head down, and approaching from visible areas. Passengers must adhere to these guidelines for safety.
Step-by-step explanation:
When briefing passengers on embarking and exiting a helicopter, the pilot should ensure that safety is the primary concern. The correct approach includes:
- Waiting for the pilot to signal and give instructions for entering and exiting.
- Always keeping your head down to avoid the rotor blades and approaching the helicopter from the front or sides where the pilot can see you.
- Being cautious of the helicopter's movements as the craft and its rotors can be affected by external forces such as air pushing upward.
It is important for passengers to follow the pilot's directions closely to maintain safety.
