CFRN Aviation Safety and Survival 5

Question 1

In rotor-wing aircraft operations, 'wire strike' refers to collision with power lines. Which approach phase carries the highest wire strike risk?

Accepted Answer

Low-level approach to an unprepared landing zone at night or in low visibility

Answer

Low-level approaches to unprepared LZs at night or in low visibility dramatically increase wire strike risk because lines are nearly impossible to see.

Question 2

A CFRN is responding to a scene where the landing zone has a 5% slope. Which direction should the helicopter land relative to the slope?

Accepted Answer

Facing uphill so the nose points toward the high side

Answer

Helicopters should land facing uphill (nose upslope) to prevent dynamic rollover and maintain rotor clearance from rising terrain.

Question 3

In the event of smoke in the helicopter cabin, what is the FIRST priority for the flight nurse?

Accepted Answer

Don oxygen mask and notify the pilot immediately

Answer

The flight nurse should first don their oxygen mask to maintain their own effectiveness, then immediately alert the pilot to the smoke emergency.

Question 4

What is the primary reason flight crew should avoid carbon fiber or aluminum frame glasses during flights?

Accepted Answer

They can become projectiles in a crash due to their rigidity

Answer

Rigid frame glasses can become lethal projectiles during crash deceleration; flexible frames or contact lenses are preferred for flight crew.

Question 5

Which standardized communication technique is recommended in HEMS to reduce read-back errors during critical phases of flight?

Accepted Answer

Closed-loop communication with mandatory read-back confirmation

Answer

Closed-loop communication requires the receiver to read back instructions, confirming accurate receipt — the aviation-standard method to prevent miscommunication errors.
