Robinson R22 Flashcards
Engine Fire (In Flight)
- Enter autorotation
- Cabin Heat – OFF (if time permits)
- Cabin Vent – ON (if time permits)
- If engine is running, perform normal landing, then pull fuel mixture OFF and shut fuel valve OFF;
If engine stops running, shut fuel valve OFF and complete autorotation landing - Battery switch – OFF
- If time permits, apply rotor brake to stop rotors
- Exit helicopter
Power Failure (Above 500’ AGL)
- Lower collective immediately to maintain rotor RPM.
- Establish a steady glide at approximately 65 KIAS.
- Adjust collective to keep RPM between 97 and 110% or apply full down collective if light weight prevents attaining above 97%.
- Select landing spot and, if altitude permits, maneuver so landing will be into wind.
- A restart may be attempted at pilot’s discretion if sufficient time is available.
- If unable to restart, turn unnecessary switches and fuel valve off.
- At about 40 feet AGL, begin cyclic flare to reduce rate of descent and forward speed.
- At about 8 feet AGL, apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. Touch down in level attitude with nose straight ahead.
Power Failure (Between 8’ and 500’ AGL)
- Lower collective immediately to maintain rotor RPM.
- Adjust collective to keep RPM between 97 and 110% or apply full down collective if light weight prevents attaining above 97%.
- Maintain airspeed until ground is approached, then begin cyclic flare to reduce rate of descent and forward speed.
- At about 8 feet AGL, apply forward cyclic to level ship and raise collective just before touchdown to cushion landing. Touch down in level attitude and nose straight ahead.
Power Failure (Below 8’ AGL)
- Apply right pedal as required to prevent yawing.
- Allow aircraft to settle.
- Raise collective just before touchdown to cushion landing.
Maximum Glide Distance Configuration
- Airspeed approximately 75 KIAS.
- Rotor RPM approximately 90%.
- Best glide ratio is about 4:1 or one nautical mile per 1500 feet AGL.
CAUTION
Increase rotor RPM to 97% minimum when autorotating below 500 feet AGL.
Air Restart Procedure
CAUTION
Do not attempt restart if engine malfunction is suspected or before safe autorotation is established.
- Mixture full rich.
- Primer (if installed) - down and locked.
- Throttle closed, then cracked slightly.
- Actuate starter with left hand.
Emergency Water Landing - Power Off
- Follow same procedures as for power failure over land until contacting water. If time permits, unlatch doors prior to water contact.
- Apply lateral cyclic when aircraft contacts water to stop rotors.
- Release seat belt and quickly clear aircraft when rotors stop.
Emergency Water Landing - Power On
- Descend to hover above water.
- Unlatch doors.
- Passenger exit aircraft.
- Fly to safe distance from passenger to avoid possible injury by rotors.
- Switch battery and alternator OFF.
- Roll throttle off into overtravel spring.
- Keep aircraft level and apply full collective as aircraft contacts water.
- Apply lateral cyclic to stop rotors.
- Release seat belt and quickly clear aircraft when rotors stop.
Loss of Tail Rotor Thrust in Forward Flight
Failure is usually indicated by nose right yaw which cannot be corrected by applying left pedal.
- Immediately enter autorotation.
- Maintain at least 70 KIAS if practical.
- Select landing site, roll throttle off into overtravel spring, and perform autorotation landing.
NOTE:
When a suitable landing site is not available, the vertical stabilizers may permit limited controlled flight at low power settings and airspeeds above 70 KIAS; however, prior to reducing airspeed, enter full autorotation.
Loss of Tail Rotor Thrust in Hover
Failure is usually indicated by nose right yaw which cannot be stopped by applying left pedal.
- Immediately roll throttle off into overtravel spring and allow aircraft to settle.
- Raise collective just before touchdown to cushion landing.
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 practical.
Governor Failure
If engine RPM governor malfunctions, grip throttle firmly to override the governor, then switch governor off. Complete flight using manual throttle control.
Land Immediately
Land on the nearest clear area where a safe normal landing can be performed. Be prepared to enter autorotation during approach, if required.
Land as soon as practical
Land site is at pilot’s discretion based on nature of problem and available landing areas. Flight beyond nearest airport is not recommended.
Three conditions requiring autorotation
PDOP
Power Failure
Drivetrain Failure
Oil Pressure Failure
