R22 Knowledge Test The test consists of 30 questions. You are given 20' to complete the test. Name or nickname (Will be displayed on the leaderboard) 1. Prior to a ground contact (run-on) autorotation landing, a detent spring, located in the vertical throttle push-pull tube:allows the pilot to shut down the engine simulatingallows the pilot to roll his throttle off beyond the idle stop,thus preventing the throttle correlation from adding power when the collective stick is raised.prevents the pilot from shutdown the engine2. A caution CLUTCH LIGHT on the panel is ON whenever the electric actuator is:engagingoperatingdisengaging3. Avoid removing left door:To protect tail rotor from loose objectsTo keep good flight qualitiesT o remain within lateral CG limits4. The following constitutes abnormal operation of the CLUTCH warning light:The light remains on for more than 7-8s.The light comes on momentarilyThe light remains on for more than 5-6s.5. How many Vee-Belts does the R-22 helicopter have?2 double4 single4 double6. The low RPM light and horn indicate rotor RPM:At 98 %At 97 %At 97 % or below7. The maximum oil temperature is:245°F75°F275°F8. A pilot with 150 helicopter hours, 10 000 aeroplane hours and 50 hours on the R-22 wants to fly. The wind is 5 gusting 25 knots. May he fly?NoYesYes, but not in turbulent weather9. If oil is not visible in the sight gage, oil must be added to the tail rotor gearboxFalse, there is no way to check visually the tailrotor gearbox oil levelTrue, provided the helicopter sits levelTrue10. 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 onlyCotter pins are not required at allTrue (older doors may only have provisions for upper cotter pins)11. According to the POH, the information contained in Section 2, Limitations, is approved by the:FAACAAJAA12. Maximum operating density altitude:9000 ft9600 ft14000 ft13. Below what rotor RPM can irrecoverable blade stalling occur at sea level?90 %86 %80 %14. The governor is active above:75% rotor RPM.80% rotor RPM.55% rotor RPM.15. Power off rotοr speed limits:maximum 104 %, minimum 90 %maximum 102 %, minimum 99 %maximum 110 %, minimum 90 %16. A drive system failure may be indicated by:Decreasing rotor RPM while engine RPM is increasingboth the other two answers are correctUnusual noise or vibration17. Color code for instrument markings, RED:Normal operating rangeIndicates Operating limitsPrecautionary operating range18. If right roll in low ‘G’ condition is encountered in flight:Gradually apply forward cyclicGradually apply aft cyclic to restore positive ‘G’ forces and main rotor thrustApplyl ateral cyclic to eliminate roll19. The main rotor gearbox is:Lubricated by T eflon (PTFE) bushesSplash lubricatedLubricated by a pressure-fed nozzle on each bearing20. The low hover point on the H-V diagram:depends on the density altitudeis 5 ft AGLis 10 ft AGL21. Panel lights function:only when the NAV LTS switch is offonly when the LANDING light switch is ononly when the NAV LTS switch is on22. Cooling air to the engine is supplied:By a direct drive cooling fanBy the free-streamthe engine is water cooled23. Flight in known icing conditions:is prohibitedis allowed only in light ice conditionsis allowed provided optional equipment is installed24. Correct throttle linkage (throttle-collective-butterfly valve) adjustment may be verified during preflight:TrueThere is not such a linkage on the R-22False25. The governor is only active:above 80%below 80%above 82%26. PARKING in windy conditions, align rotor blades:slightly offset from fore and aftapproximately fore and aftapproximately left and right27. If STARTER-ON light does not go out when ignition switch is released:pull mixture to idle cut-offTurn fuel shut off valve offContinue an attempt to start28. All fuel drains should be opened daily:prior to flight to check for the correct fuel quantityafter flightprior to flight to check for water,sediment,and fuel type/grade29. For pushing the helicopter on the ground:The outboard part of the horizontal stabilizer may be usedThe tail skid may be usedOne of the vertical frame tubes may be used30. The Height-Velocity diagram has been demonstrated:both the other two answers are correctat sea level and 1370 lbsat 7000 ft density altitude and 1300 lbsyou can go back for a final check or press SUBMIT to validate.
