CFRN Aviation Safety and Survival 2

Question 1

During a helicopter emergency landing on water, at what point should flight crew members inflate their personal flotation devices (PFDs)?

Accepted Answer

Only after exiting the aircraft

Answer

PFDs should be inflated after exiting the aircraft to prevent being trapped inside by the buoyancy during underwater escape.

Question 2

What is the primary purpose of a helicopter Emergency Locator Transmitter (ELT)?

Accepted Answer

To automatically broadcast distress signals on 406 MHz to satellites after a crash

Answer

The ELT automatically activates on impact and broadcasts on 406 MHz to COSPAS-SARSAT satellites to initiate search and rescue.

Question 3

A flight nurse notices the helicopter is experiencing unusual vibrations. What is the most appropriate immediate action?

Accepted Answer

Notify the pilot immediately and prepare for possible emergency landing

Answer

Unusual vibrations can indicate rotor or mechanical failure, requiring immediate pilot notification and preparation for emergency landing.

Question 4

Which type of fire extinguisher is most appropriate for use in an aircraft cabin electrical fire?

Accepted Answer

Halon or CO2 extinguisher

Answer

Halon or CO2 extinguishers are used for electrical fires in aircraft because they are non-conductive and leave no damaging residue.

Question 5

What is the correct CFRN response if a patient's oxygen tank is damaged during a hard landing and begins to leak inside the aircraft?

Accepted Answer

Notify the pilot, land immediately, and move the patient away from the tank

Answer

A leaking oxygen tank creates a fire hazard; the priority is immediate landing and removing the patient from proximity to the leaking cylinder.
