Question 1

General

Answer 1

.

Question 2

Land as soon as practical

Answer 2

Land at the nearest airport or other facility where emergency maintenance may be performed.

Question 3

Power failure may be caused by?

Answer 3

Either

1) Engine failure
2) drive system failure

Question 4

Power failure is usually indicated by?

Answer 4

Low RPM horn.

Question 5

An engine failure may be indicated by?

Answer 5

1) change in noise level
2) nose left yaw
3) oil pressure light
4) decreasing engine RPM

Question 6

A drive system failure may be indicated by?

Answer 6

1) an unusual noise or vibration
2) nose right or left yaw
3) decreasing rotor RPM while engine RPM is increasing

Question 7

Caution! What is required When collective is lowered at high speed and forward CG?

Answer 7

Aft cyclic

Question 8

Caution! What should a pilot avoid during touch down or during ground slide to prevent possible blade strike to tail cone?

Answer 8

Aft cyclic

Question 9

What to do when power fails at 500ft AGL

Answer 9

1) lower collective immediately to maintain RPM and enter normal autorotation.
2) establish a steady glide at approximately 65 KIAS.
3) adjust collective to keep RPM in the green arc
Or apply full down collective if light weight prevents attaining above 97%
4) select landing spot, and (if altitude permits) maneuver so landing will be into wind.
5) a restart may be attempted at pilots discretion if sufficient time is available.
6) if unable to restart, turn off unnecessary switches and shut off fuel.
7) at about 40ft AGL begin cyclic flare to reduce the rate of decent and forward airspeed
8) at about 8ft AGL, apply forward cyclic to level ship and raise collective just before touchdown to cushion the landing. Touch down in level attitude with nose straight ahead.

Question 10

If power failure occurs at night what should a pilot not turn on until what altitude? And why?

Answer 10

Landing lights
Above 1000 ft AGL
To preserve battery power

Question 11

Power failure between 8-500 ft AGL

Answer 11

1) auto rotate

Question 12

Power failure below 8ft AGL

Answer 12

1) apply right pedal as required to prevent yawning
2) allow aircraft to settle
3) raise collective just before touchdown to cushion landing.

Question 13

What is Maximum Glide Distance Configuration?

Answer 13

1) airspeed approximately 75 KIAS
2) Rotor RPM approximately 90%
3) best glide ratio 4:1 or one nautical mile per 1500 ft AGL

Question 14

Caution!

When auto rotating below 500 ft AGL what is the minimum rotor RPM that should be used?

Answer 14

97%

Question 15

How does one perform an air restart procedure?

Answer 15

1) mixture- full rich
2) primer( if installed) - down and locked
3) throttle - closed, then cracked slightly
4) actuate starter with left hand.

Question 16

Caution!

Do not attempt a restart if?

Answer 16

Engine malfunction is suspected or before a safe auto rotation is established.

Question 17

Ditching power off?

Answer 17

1) Auto rotate until contact with water.
2) apply lateral cyclic when aircraft contacts water to stop the blades from turning.
3) release seat belt and quickly clear aircraft when blades stop rotating.

Question 18

Ditching power on?

Answer 18

1) descend to hover above water
2) unlatch doors
3) passenger exit aircraft
4) fly safe distance from passenger to avoid possible injury by blades.
5) switch off battery and alternator
6) roll throttle off into over travel spring.
7) keep aircraft level and apply full collective as aircraft contacts water.
8) apply left lateral cyclic to stop blades from rotating.
9) release seat belt and quickly clear aircraft when blades stop rotating.

Question 19

Loss of tail rotor thrust during forward flight?

Answer 19

1) failure is indicated by a nose right yaw that can not be corrected by using left pedal.
2) immediately enter auto rotation.
3) maintain at least 70 KIAS if practicle
4) select landing site, roll throttle off into over travel spring, and perform auto rotation landing.

Question 20

Loss of tail rotor thrust during a hover?

Answer 20

1) failure is indicated by an uncomanded nose right yaw that can not be corrected by using left pedal.
2) immediately roll throttle off into over travel spring and alow aircraft to settle.
3) raise collective just before touchdown to cushion landing.

Question 21

Engine fire during start on ground?

Answer 21

1) continue cranking to attempt to suck the flames and excess fuel through the carburetor into the engine.
2) if engine starts let it run at 50%-60% RPM for a short time, shut down, and inspect for damage.
3) if engine fails to start shut off fuel and master battery switch.
4) extinguish fire with extinguisher, wool blanket, or dirt.
5) inspect for damage.

Question 22

Fire in flight?

Answer 22

1) Enter auto rotation
2) master battery switch OFF
3) cabin heat OFF
4) cabin vent ON
5) if engine is running, perform a normal landing and immediately shut OFF fuel valve.
6) if engine failes, shut OFF fuel valve and execute autorotation landing.

Question 23

Electrical Fire in Flight?

Answer 23

1) Master battery switch- OFF
2) alt switch - OFF
3) land immediately
4) extinguish fire and inspect for damage.

Question 24

Caution!

What is inoperative with both master battery and alternator switches off?

Answer 24

Low RPM warning system,

And governor.

Question 25

Tachometer failure?

Answer 25

Use remaining tach to monitor RPM. If not clear which tach has malfunctioned allow governor to control the RPM and land as soon as practical.

Question 26

Governor failure?

Answer 26

Grip the throttle firmly to over ride the governor, then switch governor off. Complete flight using manual throttle control.
