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. Upon inadvertently encountering moderate, severe, or extreme turbulence adjust forward speed:to between 53 KIAS and 0,7Vne but no lower than 50 KIAS.to between 60 KIAS and 0,8Vne but no lower than 54 KIAS.to between 60 KIAS and 0,7Vne but no lower than 57 KIAS.2. Avoid removing left door:To protect tail rotor from loose objectsTo keep good flight qualitiesT o remain within lateral CG limits3. A small quantity of fuel should be drained from the gascolator and from each tank:prior to the first flight each dayafter every flightnever4. The best rotor RPM to allow maximum glide distance during autorotation is:104%90%97%5. There is no shaded area (other than the high speed/low high) on the H-V diagram for speeds above:60 knots30 knots20 knots6. The OIL PRESSURE gage Lower red line corresponds to:95 psi55 psi25 psi7. A pilot arrives at the airport during a heatwave. He/she/it should be:Careful, because the air density is decreased.Careful, because the helicopter has a maximum demonstrated operating temperature.Pleased, because the helicopter’s performance is improved.8. If uncommanded pitch, roll or yaw resulting from flight in turbulence is encountered in flight:minimize cyclic control input in turbulenceapply controls as necessary to maintain controlincrease collective to maintain positive climb9. Speed for maximum rate of climb (VY) is:60 KIAS70 KIAS53 KIAS10. Airspeed indicator green arc:53-102 knots50-102 knots60-102 knots11. Below what rotor RPM can irrecoverable blade stalling occur at sea level?86 %90 %80 %12. Recommended initial landing approach speed is:60 KIAS53 KIAS65 KIAS13. All primary controls are actuated through:cableswires and electrical motorspush-pull tubes and bellcranks14. The R-22 vertical fin may permit limited controlled flight after a Loss of tail rotor thrust during forward flight:Yes above 70 KIASYes above 85 KIASYes maintaining at least 60 KIAS if practical15. When operating at high density altitudes, governor response rate:may be too fastmay be too slowremains the same irrespective of altitude16. The Demonstrated Operating Temperature at an altitude of 4000’ is:23° C above ISA, i.e 30°C32° C above ISA, i.e 39°C.38°C17. The inertia reel of the seat belts:locks by pushing the lock switch located under the seatwill lock if there is sudden movementnever locks18. Flight in known icing conditions:is prohibitedis allowed provided optional equipment is installedis allowed only in light ice conditions19. Which item, when unserviceable, precludes any further flight?AlternatorOAT gaugeAny of the other two20. The R-22 Maintenance Manual requires a complete inspection:after every 100 hours of operationafter every 50 hours of operationafter every 25 hours of operation21. Maximum oil pressure during start & warm up:95 psi55 psi115 psi22. The engine is:water-cooledoil-cooledair-cooled23. Indicated airspeeds (KIAS) shown on graphs assumes:zero instrument erroran instrument error according to the relevant chart on POH5 knots error24. The blade skins (main rotor) are made of:composite materialsteelaluminum25. Loss of tail rotor thrust during forward flight:Maintain at least 85 KIAS if practicalMaintain at least 60 KIAS if practicalMaintain at least 70 KIAS if practical26. Induction air enters through an inlet:on the aft section of the aircrafton the left side of the aircrafton the right side of the aircraft27. When the fuel gages read E the tanks:are empty except for a small quantity of unusable fuelare emptyare empty except for 1⁄4 of fuel in the main tank28. 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 levelTrueTrue, provided the helicopter sits level29. The main gearbox overtemp light is actuated by a temperature switch located:near the input pinion bearing.near the output pinion bearing.there is not such a warning light on the R-22 helicopter30. LOW RPM horn & CAUTION light:apply aft cyclicroll throttle on, lower collective and in forward flight apply aft cycliclower collectiveyou can go back for a final check or press SUBMIT to validate.
