For our members who own and operate Robinson helicopters, the newsletter quiz in this issue pertains to the operation of R44 Raven helicopters. Except for the extra credit question, the answers to the questions in this quiz can be found in the Pilot’s Operating Handbook for the R44 II helicopter.

1. The Robinson R-44 II helicopter is equipped with -

A. aLycoming IO-540-AE1A5, six cylinder, horizontally opposed, direct drive, air cooled, fuel injected, normally aspirated engine.

B. aLycoming O-360 air-cooled, carburetor-equipped engine.C. aRolls-Royce RR300, twin-spool, turbo shaft engine.D. a Lycoming O-540-F1B5, six cylinder, horizontally opposed, direct drive,

aircooled, carbureted, normally aspirated engine

2. A pushover (forward cyclic maneuver) performed from level flight or following a pullup causes a low-G (near weightless) condition which can result in catastrophic loss of lateral control. To eliminate a low-G condition -

A. immediately apply full aft cyclic.B. should a right roll commence during a low-G condition, apply gentle aft

cyclic to reload rotor before applying lateral cyclic to stop the roll.C. immediately apply forward cyclic.D. lower the collective and increase rotor RPM.

3. The red cross hatch marking on the airspeed indicator signifies -

A. an operating limit. The pointer should not enter red during normal operation.

B. a precautionary or special operating procedure range.C. power off Vne.D. normal operating range.

4. The green arc on the rotor tachometer indicates -

A. 0 to 130 KIASB. 90 to 108%C. 55 to 95 PSID. 15.0 to 23.3 in. Hg

5. Minimum solo pilot weight in the R44 II helicopter is –

A. 200 pounds

6. Best glide ratio in the R44 II is _____ or 1 nautical mile per _____ feet AGL -

8. The governor maintains engine RPM by sensing changes and applying corrective throttle inputs through a friction clutch which can be easily overridden by the pilot. The governor is only active above _____ engine RPM and can be switched on or off using the toggle switch on the _______________.

A. 75%, end of the right seat collective.B. 80%, end of the right seat collective.C. 75%, instrument panel, next to the clutch control switch.D. 80%, instrument panel, next to the clutch control switch.

9. Which statement(s) is/are true regarding the hydraulic system?

A. Hydraulically boosted main rotor flight controls eliminate cyclic and collective feedback forces.

B. Normal operating pressure is 1,200 to 1,550 PSI.C. Pulling the HYD circuit breaker is an alternate means to turn off the

hydraulics.D. If you have an inflight hydraulics failure, turn the hydraulics switch off

and land as soon as possible.

10. Which statement(s) is/are true regarding the rotor brake?

A. Rotor brake must be released before starting the engine.B. When the rotor brake is engaged, starter buttons are disabled.C. After pulling idle cutoff, wait at least 30 seconds before applying the rotor

brake.

D. Applying rotor brake with enough force to stop the rotor in less than 20 seconds may permanently damage the rotor brake shoes.

E. All of the above answers are correct.F. None of the above answers are correct.
