CFRN Aviation Safety and Survival 4

Question 1

What minimum safe distance should bystanders maintain from a helicopter landing zone during active operations?

Accepted Answer

100 feet

Answer

A minimum of 100 feet (approximately 30 meters) is the standard safe distance for bystanders from an active helicopter landing zone.

Question 2

Which physiological condition is MOST associated with spatial disorientation during night or instrument flight conditions?

Accepted Answer

Vestibular conflict between the inner ear and visual inputs

Answer

Spatial disorientation occurs when vestibular (inner ear) sensations conflict with visual information, particularly dangerous when visual cues are absent.

Question 3

During an in-flight emergency, a CFRN's primary responsibility regarding the patient is to:

Accepted Answer

Secure the patient and all equipment, then brace for landing

Answer

In an in-flight emergency, the CFRN must secure the patient and all loose equipment to prevent projectile injuries during a crash or hard landing.

Question 4

Which personal protective equipment (PPE) item is considered MOST critical for flight crew to wear at all times during operations?

Accepted Answer

Flame-resistant flight suit

Answer

A flame-resistant flight suit is the most critical PPE because post-crash fires are a major cause of crew fatalities in helicopter accidents.

Question 5

What is the significance of 'density altitude' for helicopter flight nurses?

Accepted Answer

It affects aircraft performance by reducing lift capacity in hot, high, or humid conditions

Answer

High density altitude (hot, high, humid conditions) reduces rotor efficiency and engine output, limiting payload capacity and increasing risk of crashes.
