Answer 16

If conning/controlling the aircraft, relinquish control/con. Then say “(your position) GOGGLE FAILURE” on ICS

Question 17

What are the HF warnings?

Answer 17

Do not transmit:
when anyone is on or near the helicopter,
when the transmission access doors are open, or
when the blades are folded

To reduce radiation risk to passengers the HF operator shall ensure, prior to transmitting, that no personnel are seated within 30cm of the left fuselage window or within 60cm of the HF coupler.

Question 18

Describe RADHAZ SAFE

PORT
STARBOARD
FORWARD
AFT

Answer 18

150 - 000 safe PORT
000 - 210 safe STARBOARD
150 - 270 safe AFT
315 - 135 safe FORWARD

Question 19

What are the rules regarding high level shit-offs during HIFR

Answer 19

PRI and SEC TEST are used to ensure that high level shut offs are fully functional

They should be tested if intending to fuel greater than 3000lbs. If unserviceable or untested the fuelling shall stop when either tank reaches 2000lbs.

Note: there should be at least 2000lbs on board prior to testing (HIFR)

Question 20

Describe emergency breakaway considerations

Answer 20

Hose breaks at 400-500lbs tension
Will leave approx 10ft attached to helo 
Couplings limit fuel spilt
To continue HIFR after breakaway, reassemble hose, recirculate for 5 mins and retest before commencing
Fuelling rate is 420lbs/min

Question 21

Define the Final Approach Area

Answer 21

Area extending 2.5nm out from ship 20 deg either side of the Final Approach Course. Should be clear of obstructions prior to approach.

Note if IFR approach in IMC

• wind must be within 30 deg of ships heading
• Final Approach Course shall be within 30 degrees of the ships heading
• Final approach shall be clear of all obstructions

Question 22

Describe the Final Approach Course

Answer 22

Bearing assigned by the SAC within 30 degrees of the 180 from the ship, out to 2nm

Question 23

Describe the Delta

Answer 23
