Robinson EPs Flashcards
Memorize R22 EPs before solo
Power Failure Above 500ft
- Lower collective immediately
- Establish a steady glide at 65 KIAS
- Adjust collective to keep RPM between 97% and 110%
- Select landing spot, if altitude permits land facing into the wind
- A restart may be attempted at pilot’s discretion, if time permits
- If unable to restart, turn unnecessary switches and fuel valve off
- At 40ft begin flare to reduce rate of descent and forward speed.
- At 8ft apply forward cyclic to level out and raise collective just before touch down to cushion landing.
Power Failure Between 8ft and 500ft
- Lower collective immediately
- Adjust collective to keep RPM between 97% and 110%
- Maintain airspeed until ground is approached, then begin flare
- At 8ft apply forward cyclic to level out and raise collective just before touch down to cushion landing.
Power Failure Below 8ft
- Apply right pedal
- Allow aircraft to settle
- Raise collective just before touchdown to cushion landing.
Maximum Glide Distance Configuration
- Airspeed 75 KIAS
- Rotor RPM 90% increase RPM to 97% below 500 ft
- Best glide is 4:1 or 1nm/1500ft AGL
Air Restart Procedure
- Mixture- full rich
- Primer(if installed)- down and locked
- Throttle- closed, then cracked slightly
- Actuate start with left hand. Do not restart if engine malfunction is suspected
Emergency Water Landing - Power Off
- Follow same procedures as for power failure, if time permits unlatch doors prior to water contact
- Apply lateral cyclic when in contact with 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
- Switch battery and alternator off
- Roll throttle off into overtravel spring
7.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
- Immediately enter autorotation
- Maintain at least 70 KIAS
- Select landing site, roll throttle off into overtravel spring, and perform autorotation landing
Loss of Trail Rotor Thrust in Hover
- Immediately roll throttle off into overtravel spring and let aircraft settle
- Raise collective just before touchdown
Headset Audio Failure
If headset fails, land as soon as practical.
Caution
For aircraft which provide low RPM horn through the audio system, pilot will not hear horn with a failed headset.
Engine Fire During Start in ground
- Cranking - Continue and attempt to start which would suck flames and excess fuel into engine
- If engine starts, run at 50-60% RPM for a short time
- Fuel mixture- Off
- Fuel Valve - Off
- Battery Switch- Off
- If time permits, apply rotor brake
- Exit helicopter
Engine Fire in Flight
- Enter Auto
- Cabin heat - OFF
- Cabin vent - ON
- If engine is running, perform normal landing, then fuel mixture OFF and Fuel Valve
- Battery switch - OFF
- Apply rotor brake if time permits
- Exit Helicopter
Electrical Fire in Flight
- Battery and alt switches - OFF
- Open cabin vents
- Land Immediately
- Fuel mixture OFF and fuel valve
- Apply rotor brake if time permits
- Exit helicopter
Tachometer Failure
Use remaining tach to monitor RPM. If it’s not clear or if both malfunction, allow governor to control RPM and land as soon as practical.
Governor
Grip throttle to override, switch governor off, complete flight using manual throttle.
Warning/Caution Lights- Oil
Indicates 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. Continued operation without oil pressure will cause serious engine damage and engine failure may occur.
Audio Alerts
Low RPM Horn and Light are disabled when collective full down.
High RPM Warble- Raise collective to control RPM.
Information Per FAA AD 95-26-04
- Right Roll in Low G- Gradual aft cyclic, then correct for the right roll
- Uncommanded Pitch roll or yaw fro turbulence- Maintain rotor RPM, positive G
- Inadvertent encounter with moderate, severe, or extreme turbulence- Avoid areas of turbulence, if not land as soon as practical.
Land Immediately
Land in the nearest clear area where a safe normal landing can be preformed
Land as soon as Practical
Landing site is at pilot’s discretion based on nature of problem and available landing areas.
Warning/Caution Lights- MR Temp
Indicates excessive temperature of main rotor gearbox
Warning/Caution Lights- MR Chip
Indicates metallic particles in main rotor gearbox
Warning/Caution Lights- TR Chip
Indicates metallic particles in tail rotor gearbox
Caution
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.
Warning/Caution Lights- Low Fuel
Indicates 1 gallon of usable fuel remaining for all-aluminum fuel tanks (5min of flight) or 1.5 gallons for bladder-style tanks(10min of flight time)
Warning/Caution Lights- Clutch
indicates clutch actuator circuit is on, either engaging or disengaging clutch. When switch is in the engage position, light stays on until belts are properly tensioned. Never take off before light goes out.
If light flickers or comes on in flight and does not go out within 10 sec, pull clutch circuit breaker and land as soon as practical. Reduce power and land immediately if indications of drive system failure.
Warning/Caution Lights- ALT
Indicates low voltage and possible alternator failure. Turn off nonessential electrical equipment and switch ALT off and back on after 1 sec to rest alternator control unit. Land as soon as practical if light stay on. Continued flight without functioning alternator can result in loss of power to tachs, producing a hazardous flight condition.
Warning/Caution Lights- STARTER ON
Indicates starter motor is engaged. If light does not go out when ignition switch is released from start position, immediately pull mixture off and turn battery switch off. have starter serviced.
Warning/Caution Lights- Low RPM
Indicates rotor speed below 97% RPM. To restore RPM, immediately lower collective, roll throttle on and, in forward flight, apply aft cyclic. Light is disabled when collective is full down.
Warning/Caution Lights- GOV OFF
Indicates engine RPM governor is switched off.
Warning/Caution Lights- Carbon Monoxide
Indicates elevated levels of carbon monoxide
MONOXIDE (CO) in cabin. Shut off heater and open nose and door vents. If hovering, land or transition
to forward flight. If symptoms of CO poisoning (headache, drowsiness, dizziness) accompany light, land immediately.
Warning/Caution Lights- Brake
Indicates rotor brake is engaged. Release immediately in flight or before starting engine.
Warning/Caution Lights- Full Throttle
Indicates engine near full throttle. The governor will be ineffective because it cannot increase throttle to maintain RPM. Lower collective as required to extinguish light.
