• Governor 
• OAT gauge (outside air temp) 
• Alternator 
• Low rotor rpm warning system

one pilot from the right seat only, left seatbelt must always be buckled

only when landing, navigation, instrument,and anti collision lights are operational. orientation must be maintained by visual reference to ground objects illuminated by lights on the ground or adequate celestial illumination

24.1 inhg

• no flights in wind above 25 knots
• no flights when wind gust spreads exceed 15 knots
• no continued flight into moderate, severe, or extreme turbulence

adjust forward airspeed to 60 KIAS and .7 Vne but no lower than 57 KIAS

changes in altitude or attitude, variations in indicated airspeed, and aircraft occupants feel definite strains against seat belts

land on the nearest clear area where a safe normal landing can be performed. be prepared to enter autorotation during approach, if required

landing site is at pilots discretion based on nature of problem and available landing areas. flight beyond nearest airport is not recommended

a change in engine noise level, nose left yaw, an oil pressure light, or decreasing engine rpm

an unusual noise or vibrations, nose right or left yaw, or decreasing rotor rpm while engine rpm is increasing

lower collective to enter autorotation

• lower collective immediately to maintain rotor rpm 
•  establish a steady glide at approximately 65 KIAS 
•  adjust collective to keep RPM between 97 and 100% 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 the wind 
• a restart may be attempted at pilots discretion if sufficient time is available 
• if unable to restart, turn unnecessary switches and fuel valve to off 
• at about 40 feet AGL, begin cyclic flair 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. touchdown in level attitude with nose straight ahead

• 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 flair to reduce rate of descent and forward speed 
• at about 8 feet AGL apply forward cyclic to level ship and raise collective to cushion landing. touch down in level attitude and nose straight ahead

• apply right pedal as required to prevent yawing 
• allow aircraft to settle
• raise collective just before touchdown to cushion landing

• airspeed approximately 75 KIAS
• rotor RPM approx 90%
• best glide ration is about 4:1 or one nautical mile per 1,500 feet AGL
• min descent rate is 53Knots and 90 percent rpm

97%

• mixture full rich
• primer ( if installed) down and locked 
• throttle closed then cracked slightly 
• actuate starter with left hand

• immediately enter autorotation
• maintain at least 70 KIAS if practical 
• select landing sight, roll throttle off into over travel spring and preform autorotation landing

• immediately roll throttle off into over travel spring and allow aircraft to settle 
• raise collective just before touchdown to cushion landing

• cranking- continue and attempt to start which would suck flames and excess fuel into engine 
• if engine starts, run at 50-60 % rom for a short time 
• fuel mixture off 
• fuel valve off 
• batt switch off 
• if time permits apply rotor brake to stop rotors 
• exit helicopter

• enter autorotation 
• cabin heat off (if installed and time permits) 
• cabin vent on ( if time permits)
• if engine is running perform normal landing then fuel mixture off and fuel valve off if engine stops running fuel valve off and complete autorotation landing 
• battery switch off 
• if time permits apply rotor brake to stop rotors 
• exit helicopter

• battery and alternator switches off 
• open cabin vents 
• land immediately 
• fuel mixture off and fuel valve off 
• if time permits apply rotor brake to stop rotors 
• exit helicopter

if it is not clear which tach is malfunctioning or both tachs malfunction allow governor to control rpm and land as soon as practical

grip throttle firmly to override the governor then switch governor off, complete flight using manual throttle control

• indicates loss of engine power or oil pressure 
• check engine tach for power loss
• check oil pressure gauge and if pressure loss is confirmed land immediately 
• continued operation without oil pressure will cause serious engine damage and engine failure may occur

• indicates excessive temp of main rotor gearbox
• if light is accompanied by any indication of a problem such as noise, vibration, or temp rise land immediately 
• if there is no other indication of a problem land as soon as practical

• indicates metallic particles in main rotor gear box
• if light is accompanied by any indication of a problem such as noise, vibration, or temp rise land immediately 
• if there is no other indication of a problem land as soon as practical

• indicates metallic particles in tail rotor gearbox 
• if light is accompanied by any indication of a problem such as noise, vibration, or temp rise land immediately 
• if there is no other indication of a problem land as soon as practical

indicates aprox 1.5 gallons of fuel left for bladder tanks and will run out of fuel in apron 10 min at cruise power

• if the light flickers or comes on in flight and does not go out within 10 seconds, pull clutch CB and land as soon as practical 
• reduce power and land immediately if there are other indications of drive system failure (be prepared to enter autorotation) have drive system inspected for a possible malfunction

• turn off non essential electrical equipment and switch alt off and back on after one second to reset alternator control unit 
• if light stays on land as soon as practical

• indicates rotor brake is engaged
• release immediately in flight or before starting engine

• 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 batt switch off 
• have start motor serviced

indicates engine rpm throttle governor is off

• indicates carbon monoxide in the 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 flight, land immediately

• indicates engine near full throttle 
• the gov will be ineffective because it cannot increase throttle to maintain rpm 
• lower collective as required to extinguish light

• indicates that a rotor rpm may be below safe limits 
• to restore rpm immediately roll throttle on 
• lower collective and in forward flight apply aft cyclic 
• the horn and caution light are disabled when collective is full down
