2. Propulsion System

Question 1

Loss of CAMS

Answer 1

1. Ensure alternate CAMS assumes control.

2. Select UKB Main menu and verify the suspect CAMS status.

Question 2

Transmission/Prop Chip Indication

Answer 2

1. Zap chip. If chip clears, continue mission.
2. If chip does not clear or reappears, repeat Zap attempt. If chip clears, continue mission.
3. If chip does not clear or reappears, go hullborne, close cushion vanes, shut down affected side and investigate.

Question 3

Transmission System Low Lube Oil Pressure

Answer 3

1. When lube oil pressure drops below 40 PSIG at design N2, go hullborne, close cushion vanes, and shut down affected side.

Question 4

Transmission System High Lube Oil Temperature

Answer 4

1. When rise in component temperature is observed before CAMS alarm, reduce propeller pitch and N2 on affected side; increase propeller pitch and N2 on unaffected side.
2. If temperature exceeds 235 deg F, go hullborne, close cushion vanes, and shut down affected side.

Question 5

Loss Of Propeller/Rudder/Bow Thruster Control System Electronics

Answer 5

1. Switch to alternate control channel and attempt to cycle controls. 2. If no change in conditions, go hullborne, close cushion vanes, shut down if necessary, and investigate.

Question 6

Loss of Cushion Vane Control Electronics

Answer 6

Coming on-cushion:

1. Switch to alternate control channel and attempt to cycle control.
2. Reduce N2 to minimum, N1 to idle.
3. Depress vane dump switch. Attempt to operate vanes.
4. If no change, investigate for cause.

Coming off-cushion:

1. Switch to alternate control channel and attempt to cycle control.
2. Reduce N2 to minimum, N1 to idle.
3. If craft remains on-cushion, secure 1 or 2 main engines to bring craft off-cushion.
4. Investigate for cause.

Question 7

Loss Of Control System Hydraulics

Answer 7

1. Go hullborne, close cushion vanes, and shut down the affected side.

Question 8

Loss Of Scavenge Fan/Oil Cooler Hydraulic System

Answer 8

1. Go hullborne, close cushion vanes, and shut down affected side.

Question 9

Loss Of Lift

Answer 9

1. Use CAMS to determine craft engineering status.
2. Attempt to trim craft.
3. Increase N2 for more lift, if possible.
4. If no positive control of craft, go hullborne, and shut down affected side.

Question 10

Damage To Skirt System

Answer 10

1. Slow craft to regain maneuvering control.
2. Continue with mission at increased N2 if conditions permit.
3. If unable to regain control or if damage is severe, stop craft, go hullborne and investigate.

Question 11

Transmission and Propeller Lube System Low Reservoir

Answer 11

1. When lube oil pressure drops below 40 psig @ design N2 or high lube oil temperature is indicated, go hullborne, close cushion vanes, and shut down the affected side.

Question 12

Sprag Clutch Failure

Answer 12

Failed Disengaged:
1. Shut down affected engine.

Failed Engaged:
1. Go hullborne, close cushion vanes, and shut down unaffected engine.
