R22 Emergency Proced
Emergencies procedures for Helicopter Robinson 22
| Question | Answer |
|---|---|
| Land Immediately | Land on the nearest clear area where a safe normal landing can be performed. Be prepared to enter autorotation during the approach, if required. |
| Land as soon as practical | Land at the nearest airport or other facility where emergency maintenance may be performed. |
| Power failure above 500f Agl 1/2 | 1 Immediately enter in auto rotation. 2 Establish a steady glide at approximately 65kias. 3 adjust collective to keep RPM in green arc or apply full down collective if light weight prevents attining above 97%. |
| Power failure between 8f and 500f agl 1/2 | 1.)Immediately lower collective to maintain rotor rpm. 2.)Adjust collective to keep RPM in green arc or full down collective if light weight prevent attaining above 97%. |
| Power failure below 8f agl | 1.) Apply right pedal as required to prevent yawing. 2.) Allow aircraft to settle. 3.) Raise collective just before touchdown to cushion landing. |
| Maximum glide distance configuration | 1 Airspeed approximately 75kias. 2 Rotor RPM approximately 90%. 3 Best glide ratio is about 4:1 or one nautical mile per 1500f agl. |
| Air restart procedure | 1 mixture- full rich. 2 Primer - down and locked. 3 Throttle - closed, then cracked slightly. 4 Actuate starter with left hand. |
| Loss of tail rotor thrust during forward flight. | 1 Failure is usually indicated by nose right yaw which cannot be corrected by applying left pedal. 2 Immediately enter autorotation. 3 Maintain at least 70kias airspeed if practical. 4 Select landing site, roll throttle off into overtravel spring and perf |
| Loss of tail rotor thrust during hover | 1 Failure is usually indicated by nose right yaw which cannot be stopped by applying left pedal. 2 Immediately roll throttle off into overtravel spring and allow aircraft to settle. 3 Raise collective just before touchdown to cushion landing. |
| Engine fire during start on ground. 1/2 | 1 Cranking - continue and attempt to start which would suck flames and excess fuel through carburetor into engine. 2 if engine starts, run at 50/60% RPM for a short time, shut down, and inspect for damage. |
| Fire in flight | 1 Enter autorotation. 2 Master battery switch off. 3 Cabin heat off. 4 Cabin vent on. 5 If engine is running, perform normal landing and immediately shut off fuel valve. 6 if engine stops running, shut off fuel valve and execute autorotation landing. |
| Electrical fire in flight | 1 Master battery switch off. 2 Alt switch off. 3 Land immediately. 4 Extinguish fire and inspect for damage. |
| Tachometer failure | IF rotor or engine tach malfunctions in flight, use remaining tach to monitor RPM. IF it is not clear which tach is malfunctioning or if both tachs malfunction, allow governor to control RPM and land as soon as pratical. |
| Governor failure | if engine RPM governor malfunctions, grip throttle firmly to override the governor, then switch governor off. Complete flight using manual throttle control. |
| Oil LIght | Indicate loss of engine power or oil pressure. Check engine tach for power loss. check oil pressure gage and, if pressure loss is confirmed, land immediately. Continue operation without oil pressure will cause serious engine damage and engine failure ma |
| MR TEMP/MR CHIP/TR CHIP | If light is accompanied by any indication of a problem such as noise, vibration, or temperature rise, land immediately. IF there is no other indication of a problem, land as soon as practical. |
| Low fuel light | Indicates approximately one gallon of usable fuel remaining. The engine will run out of fuel after five minutes at cruise power. |
| Clutch light | Indicates that clutch actuator circuit is on, IF flickers or stays on for 7 or 8 seconds, pull the clutch circuit breaker, reduce power by lower collective, and land immediately, be prepare to enter autorotation. |
| Alternator light (ALT LIGHT) | Indicates low voltage and possible alternator failure. Turn off nonessential electrical equipment and switch ALT off and back on after one second to reset overvoltage relay. IF light stays on, land as soon as practical. |
| Engine Fire during start. 2/2 | 3 If engine fails to start, shut off fuel and master battery switch. 4 Extinguish fire with fire extinguisher, wool blanket, or dirt. 5 Inspect for damage. |
| Power failure above 500f agl 2/2 | 4 Select a landing spot and if altitude permits, maneuver so landing will be into wind. 5 A restart may be attempted at pilot's discretion if sufficient time is available. 6 If unable to restart, turn off unnecessary switches and shut off fuel. 7 perform |
| Power failure between 8f and 500f agl 2/2 | 3 Maintain airspeed until ground is approached and begin flare to reduce rate of descent and forward speed. 5 8f agl level ship and raise collective just before touch down to cushion land. |
