Aviation Safety and Survival Flashcards

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

Answer: Only after exiting the aircraft

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

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

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

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

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

Answer: Notify the pilot immediately and prepare for possible emergency landing

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

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

Answer: Halon or CO2 extinguisher

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

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?

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

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

During pre-flight safety briefing, a CFRN should inform the patient's family that they must NOT bring which of the following items into the helicopter?

Answer: Lighters or matches

Lighters and matches are ignition sources that pose severe fire risk in the oxygen-rich helicopter environment.

What does the aviation term 'hot loading' refer to in the context of air medical operations?

Answer: Loading or unloading patients while the rotor is still turning

Hot loading refers to patient loading or unloading while the rotor is still spinning, which requires strict safety protocols to prevent rotor strike injuries.
