One of the vertical frame tubes may be used

Yellow arc on Manifold Pressure gage:

denotes normal operation

denotes variable MAP limits

It does not exist Yellow arc on Manifold Pressure gage

Solo flight from:

right seat only

two pilots must always be present on the R-22

left seat only

2 rubber mounts

4 rubber mounts

3 rubber mounts

11.

Airspeed indicator green arc:

60-102 knots

53-102 knots

50-102 knots

12.

When installing doors, be sure to install cotter pins in upper and lower hinge pins.

False,cotter pins are required to be installed in lower hinge pins only

True (older doors may only have provisions for upper cotter pins)

Cotter pins are not required at all

13.

When determining the Lateral CG position consider:

all items on the right as positive and those on the left as negative

all items on the left as positive and those on the right as negative

all items on the left or right as positive

14.

Cooling air to the engine is supplied:

the engine is water cooled

By the free-stream

By a direct drive cooling fan

15.

R-22 engine 5 Minute takeoff rating:

131 BHP

150 BHP

124 BHP

16.

Power failure general, when collective is lowered at high speed and forward CG

No cyclic input is required

Aft cyclic is required

Use slightly forward cyclic to prevent pitch-up

17.

A sliding valve controlled by the pilot (carb heat) allows:

cool air to flow into the air-box, through the air filter and up into the carburetor

either cool or warm air to flow into the air-box, through the air filter and up into the carburator

warm air to flow into the air-box, through the air filter and up into the carburator

18.

TAKE-OFF PROCEDURE:

Verify doors latched, governor on, and RPM stabilized at 102-104%

Verify doors latched, governor on, and RPM stabilized at 101-103%

Verify governor on and RPM stabilized at 102-104%

19.

Limits indicated by installed engine oil gage:

May be exceeded on newer engine oil gages only

Are not exceeded

May be exceeded on earlier engine oil gages only

20.

The R-22 Maintenance Manual requires a complete inspection:

after every 100 hours of operation

after every 25 hours of operation

after every 50 hours of operation

21.

The Height-Velocity diagram has been demonstrated:

at sea level and 1370 lbs

at 7000 ft density altitude and 1300 lbs

both the other two answers are correct

22.

Always determine safe loading:

with empty fuel

with empty fuel as well as with take off fuel

with takeoff fuel

23.

If STARTER-ON light does not go out when ignition switch is released:

Turn fuel shut off valve off

pull mixture to idle cut-off

Continue an attempt to start

24.

If right roll in low ‘G’ condition is encountered in flight:

Applyl ateral cyclic to eliminate roll

Gradually apply aft cyclic to restore positive ‘G’ forces and main rotor thrust

Gradually apply forward cyclic

25.

Magnetos drop at 75% RPM:

7 % max in 2 sec

7 % max

2% max in 7sec

26.

The fuel is located aft of the CG of the helicopter causing the CG:

False, the CG does not move at all on the R-22

to move aft during flight

to move forward during flight

27.

Warm-up rpm:

50-60 %

70-75 %

60-70 %

28.

Total fuel, main and auxiliary, tank capacity:

main 19.2 US GALLONS, aux 10.5 US GALLONS

main 19.8 US GALLONS, aux 10.9 US GALLONS

main 25.1 US GALLONS, aux 15.2 US GALLONS

29.

At power settings below 18 inches MAP apply:

Ignore gage and apply full carb heat

Carb heat as required to keep CAT gage needle out of yellow arc
