Question 10

Headset Audio Failure

Answer 10

If headset fails, land as soon as practical.

Caution

For aircraft which provide low RPM horn through the audio system, pilot will not hear horn with a failed headset.

Question 11

Engine Fire During Start in ground

Answer 11

1. Cranking - Continue and attempt to start which would suck flames and excess fuel into engine
2. If engine starts, run at 50-60% RPM for a short time
3. Fuel mixture- Off
4. Fuel Valve - Off
5. Battery Switch- Off
6. If time permits, apply rotor brake
7. Exit helicopter

Question 12

Engine Fire in Flight

Answer 12

1. Enter Auto
2. Cabin heat - OFF
3. Cabin vent - ON
4. If engine is running, perform normal landing, then fuel mixture OFF and Fuel Valve
5. Battery switch - OFF
6. Apply rotor brake if time permits
7. Exit Helicopter

Question 13

Electrical Fire in Flight

Answer 13

1. Battery and alt switches - OFF
2. Open cabin vents
3. Land Immediately
4. Fuel mixture OFF and fuel valve
5. Apply rotor brake if time permits
6. Exit helicopter

Question 14

Tachometer Failure

Answer 14

Use remaining tach to monitor RPM. If it’s not clear or if both malfunction, allow governor to control RPM and land as soon as practical.

Question 15

Governor

Answer 15

Grip throttle to override, switch governor off, complete flight using manual throttle.

Question 16

Warning/Caution Lights- Oil

Answer 16

Indicates loss of engine power or oil pressure. Check engine tach for power loss. Check oil pressure gage and, if pressure loss is confirmed, land immediately. Continued operation without oil pressure will cause serious engine damage and engine failure may occur.

Question 17

Audio Alerts

Answer 17

Low RPM Horn and Light are disabled when collective full down.

High RPM Warble- Raise collective to control RPM.

Question 18

Information Per FAA AD 95-26-04

Answer 18

1. Right Roll in Low G- Gradual aft cyclic, then correct for the right roll
2. Uncommanded Pitch roll or yaw fro turbulence- Maintain rotor RPM, positive G
3. Inadvertent encounter with moderate, severe, or extreme turbulence- Avoid areas of turbulence, if not land as soon as practical.

Question 19

Land Immediately

Answer 19

Land in the nearest clear area where a safe normal landing can be preformed

Question 20

Land as soon as Practical

Answer 20

Landing site is at pilot’s discretion based on nature of problem and available landing areas.

Question 21

Warning/Caution Lights- MR Temp

Answer 21

Indicates excessive temperature of main rotor gearbox

Question 22

Warning/Caution Lights- MR Chip

Answer 22

Indicates metallic particles in main rotor gearbox

Question 23

Warning/Caution Lights- TR Chip

Answer 23

Indicates metallic particles in tail rotor gearbox

Caution

If light is accompanied by any indication of a problem such as noise, vibration, or temperature rise, land immediately. If there is no other indication of a problem land as soon as practical.

Question 24

Warning/Caution Lights- Low Fuel

Answer 24

Indicates 1 gallon of usable fuel remaining for all-aluminum fuel tanks (5min of flight) or 1.5 gallons for bladder-style tanks(10min of flight time)

Question 25

Warning/Caution Lights- Clutch

Answer 25

indicates clutch actuator circuit is on, either engaging or disengaging clutch. When switch is in the engage position, light stays on until belts are properly tensioned. Never take off before light goes out. If light flickers or comes on in flight and does not go out within 10 sec, pull clutch circuit breaker and land as soon as practical. Reduce power and land immediately if indications of drive system failure.

Question 26

Warning/Caution Lights- ALT

Answer 26

Indicates low voltage and possible alternator failure. Turn off nonessential electrical equipment and switch ALT off and back on after 1 sec to rest alternator control unit. Land as soon as practical if light stay on. Continued flight without functioning alternator can result in loss of power to tachs, producing a hazardous flight condition.

Question 27

Warning/Caution Lights- STARTER ON

Answer 27

Indicates starter motor is engaged. If light does not go out when ignition switch is released from start position, immediately pull mixture off and turn battery switch off. have starter serviced.

Question 28

Warning/Caution Lights- Low RPM

Answer 28

Indicates rotor speed below 97% RPM. To restore RPM, immediately lower collective, roll throttle on and, in forward flight, apply aft cyclic. Light is disabled when collective is full down.

Question 29

Warning/Caution Lights- GOV OFF

Answer 29

Indicates engine RPM governor is switched off.

Question 30

Warning/Caution Lights- Carbon Monoxide

Answer 30

Indicates elevated levels of carbon monoxide MONOXIDE (CO) in cabin. Shut off heater and open nose and door vents. If hovering, land or transition to forward flight. If symptoms of CO poisoning (headache, drowsiness, dizziness) accompany light, land immediately.

Question 31

Warning/Caution Lights- Brake

Answer 31

Indicates rotor brake is engaged. Release immediately in flight or before starting engine.

Question 32

Warning/Caution Lights- Full Throttle

Answer 32

Indicates engine near full throttle. The governor will be ineffective because it cannot increase throttle to maintain RPM. Lower collective as required to extinguish light.
