R22 EP's Flashcards
Definition of land as soon as practical-
Landing site is at the pilots discretion based on the nature of the problem and the available landing areas. Flight beyond the nearest airport is not recommend.
What is the EP for power failure above 500’ AGL
- Lower the collective immediately to maintain rotor RPM.
- Establish a steady glide rate at approximately 65 KIAS
- Adjust the collective to keep the RPM between 97% & 110% or apply full down collective if light weight prevents attaining above 97%.
- Select a landing spot and if altitude permits maneuver so that the landing can be made into the wind.
- A restart maybe attempted at the pilots discretion is sufficient time is available.
- If unable to restart turn unnecessary switches and fuel off.
- At about 40’ AGL begin the cyclic flare to reduce the rate of decent and forward speed.
- At about 8’ AGL apply forward cyclic to level the ship & raise the collective just before touch down to cushion the landing. Touch down in a level attitude with the nose straight ahead.
What is the EP for a power failure between 8’ & 500’ AGL-
- Lower the collective immediately to maintain rotor RPM.
- Adjust the collective to keep RPM between 97% to 110% or apply full down collective if light weight prevents attaining above 97%
- Maintain airspeed until ground is approach then begin cyclic flare to reduce rate of decent and forward airspeed.
- At about 8’ AGL apply forward cyclic to level the ship and raise the collective just before touchdown to cushion the landing. Touch down in a level attitude with the nose straight ahead.
What is the EP for a power failure below 8’ AGL-
- Apply right pedal as required to prevent hawing
- Allow the aircraft to settle
- Raise the collective just prior to touchdown to cushion the landing
What is the 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’ AGL
Increase rotor RPM to 97% minimum when auto rotating below 500’ AGL
What is the air restart procedure-
- Mixture full rich
- Primer if installed full down and locked
- Throttle closed then cracked slightly
- Actuate started with left hand
Do not attempt to restart if engine malfunction is suspected or before safe autorotation is established
What is the EP for an emergency water landing power off-
- Follow same procedures as for power failure over land until contacting water. If time permits unlatch the doors prior to water contact.
- Apply lateral cyclic when the aircraft contacts the water to stop the rotor.
- Release the seat belt and quickly clear the aircraft when the rotor stops.
What is the EP for an emergency water landing power on-
- Descend to a hover above the water.
- Unlatch the doors.
- Passengers exit the aircraft.
- Fly to a safe distance from the passenger to avoid possible injury by the rotor.
- Switch the battery and Alternator off.
- Roll the throttle off into the over travel spring.
- Keep the aircraft level and apply full collective as the aircraft contacts the water.
- Apply lateral cyclic to stop the rotor.
- Release the seat belt and quickly clear the aircraft when the rotor stops
What is the EP for a loss of tail rotor thrust during forward flight-
- Failure is usually indicated by a nose right yaw that can not be corrected by applying left pedal.
- Immediately enter the auto.
- Maintain at least 70 KIAS airspeed if practical.
- Select landing site roll the throttle into the overtravel spring and perform an autorotation landing.
When a suitable landing site is not available the vertical fin may permit limited controlled flight at very low power setting and airspeeds above 70 KIAS however prior to reducing airspeed re-enter full autorotation.
What is the EP for a loss of tail rotor thrust during a hover-
- Failure is usually indicated by a nose right yaw that cannot be corrected by left pedal.
- Immediately roll throttle off into to the overtravel Spring and allow the aircraft to settle.
- Raise the collective prior to touch down to cushion the landing.
What is the EP for an engine fire during start on the ground-
- Continue cranking and attempt to start which would suck flames and excess fuel through the carburetor into the engine.
- If engine starts run for a short time then shut down and inspect for damage.
- If engine fails to start shut off fuel and master battery switch.
- Extinguish fire with fire extinguisher wool blanket or dirt
- Inspect for damage
What is the EP for a fire in flight-
- Enter the auto.
- Master battery off if time permits
- Cabin heat off if installed and time permits.
- Cabin vent on if time permits
- If engine is running perform normal landing and immediately shut off fuel valve.
- If engine stops running shut off fuel and perform execute an autorotation landing.
What is the EP for an electrical fire in flight-
- Mastery battery switch off.
- Alt switch off.
- Land immediately.
- Extinguish fire and inspect for damage
Low rotor RPM waring system and governor are inoperative with master battery and alternator switches both off.
What is the EP for Tachometer failure-
If the rotor or engine tach malfunctions in flight use the remaining tach to monitor RPM. If it is not clear which tach is mail functioning or if both tachs malfunction allow governor to control RPM and land as soon as practical.
Each tach the governor and the low RPM warning horn are on separate circuits. Either the battery or the alternator can independently supply power to the tachs. A special circuit allows the battery to supply power to the tachs even if the master battery switch is off.
What is the EP for a governor failure-
If the engine RPM governor malfunctions grip the throttle firmly to override the governor then switch the governor off. Complete the flight suing manual throttle control.
