If engine does not fire after 5 to 7 seconds of cranking, repeat priming sequence and reattempt start. If engine fires momentarily but dies before or while moving mixture to rich, pull mixture off, engage starter, and push mixture slowly rich while cranking. If engine fails to start after three attempts, allow starter to cool ten minutes before next attempt. With a hot engine, it may be helpful to cool fuel in lines by running fuel pump for 30 seconds with mixture OFF prior to beginning start procedure (hold key in prime position).

CAUTION On slippery surfaces, be prepared to counter nose-right rotation with left pedal as governor increases RPM. NOTE For hydraulic system check, use small cyclic inputs. With hydraulics OFF, there should be approximately one half inch of freeplay before encountering control stiffness and feedback. With hydraulics ON, controls should be free with no feedback or uncommanded motion. NOTE Idle mixture and speed may require adjustment as conditions vary from sea level standard. Refer to R44 Maintenance Manual for idle adjustment procedure. ROBINSON MODEL R44 II SECTION 4 NORMAL PROCEDURES FAA APPROVED: 7 MAY 2019 4-9 TAKEOFF PROCEDURE 1. Verify doors latched, governor and hydraulics ON, and RPM stabilized at 101 to 102%. 2. Clear area. Slowly raise collective until aircraft is light on skids. Reposition cyclic as required for equilibrium, then gently lift aircraft into hover. 3. Check gages in green and note hover MAP. 4. Lower nose, and accelerate to climb speed following profile shown by height-velocity diagram in Section 5. Avoid exceeding two inches MAP above IGE hover power to prevent excessive nose-down attitude. If RPM drops below 101%, lower collective DOORS-OFF OPERATION Maximum airspeed with any door(s) off is 100 KIAS. Warn passengers to secure loose objects and to keep head and arms inside cabin to avoid high velocity airstream. CAUTION Ensure all seat belts are buckled during door- off flight. Rear seat bottoms may lift if not restrained and items in baggage compartments could be blown out. CAUTION Flight with left door(s) removed is not recom- mended. Loose objects exiting left doors may damage tail rotor. ROBINSON MODEL R44 II SECTION 4 NORMAL PROCEDURES FAA APPROVED: 7 MAY 2019 4-10 CRUISE 1. Verify RPM in green arc. 2. Set manifold pressure as desired with collective. Observe MAP and airspeed limits. Maximum recommended cruise speed is 110 KIAS. 3. Verify gages in green, warning lights out. CAUTION Do not exceed 110 KIAS except in smooth air, and then only with caution. In turbulence, use lower airspeed. If turbulence is significant or becomes uncomfortable for the pilot, use 60 to 70 KIAS. CAUTION In-flight leaning with engine mixture control is not allowed. Mixture must be full rich during flight. NOTE When loaded near aft CG limit, slight yaw oscil- lation during cruise can be stopped by applying a small amount of left pedal. PRACTICE AUTOROTATION – POWER RECOVERY 1. Lower collective to down stop and reduce throttle as desired for tachometer needle separation. CAUTION To avoid inadvertent engine stoppage, do not chop throttle to simulate a power failure. Always roll throttle off smoothly. Recover immediately if engine is rough or engine RPM continues to drop. NOTE Governor is inactive below 80% engine RPM regardless of governor switch position. NOTE When entering autorotation from above 6000 feet, reduce throttle slightly before lowering collective to prevent engine overspeed. 2. Adjust collective to keep rotor RPM within limits and adjust throttle for tachometer needle separation. 3. Keep airspeed 60 to 70 KIAS. 4. At about 40 feet AGL, begin cyclic flare to reduce rate of descent and forward speed. 5. At about 8 feet AGL, apply forward cyclic to level aircraft and raise collective to control descent. Add throttle if required to keep RPM in green arc. CAUTION Simulated engine failures require prompt lowering of collective to avoid dangerously low rotor RPM. Catastrophic rotor stall could occur if the rotor RPM ever drops below 80% plus 1% per 1000 feet of altitude. ROBINSON MODEL R44 II SECTION 4 NORMAL PROCEDURES FAA APPROVED: 7 MAY 2019 4-11 ROBINSON MODEL R44 II SECTION 4 NORMAL PROCEDURES FAA APPROVED: 7 MAY 2019 4-12 PRACTICE AUTOROTATION – WITH GROUND CONTACT If practice autorotations with ground contact are required for demonstration purposes, perform in same manner as power recovery autorotations except: Prior to cyclic flare, roll throttle off into overtravel spring and hold against hard stop until autorotation is complete. (This prevents throttle correlator from adding power when collective is raised.) Always contact ground with skids level and nose straight ahead. NOTE Have landing gear skid shoes inspected frequently when practicing autorotations with ground contact. Rapid wear of skid shoes may occur. HYDRAULICS-OFF TRAINING Hydraulic system failure may be simulated using the cyclic- mounted hydraulic switch. CAUTION With hydraulics switched OFF, controlling helicopter in a hover may be difficult due to control system feedback forces. CAUTION Before switching hydraulics from OFF to ON, relax force on cyclic and collective to avoid over-controlling. DESCENT, APPROACH, AND LANDING 1. Reduce power with collective as desired. Observe airspeed limits. Maximum recommended airspeed is 110 KIAS except in smooth air. CAUTION Do not initiate a descent with forward cyclic. This can produce a low-G condition. Always initiate a descent by lowering collective. 2. Make final approach into wind at lowest practical rate of descent with initial airspeed of 60 KIAS. 3. Reduce airspeed and altitude smoothly to hover. (Be sure rate of descent is less than 300 FPM before airspeed is reduced below 30 KIAS.) 4. From hover, lower collective gradually until ground contact. 5. After initial ground contact, lower collective to full down position. CAUTION When landing on a slope, return cyclic control to neutral before reducing rotor RPM. CAUTION Never leave helicopter flight controls unattended while engine is running. CAUTION Hold throttle closed if passenger is entering or exiting with engine running and left seat collective installed.

OFF NOTE If ambient temperature is above 100°F (38°C), cool down at 60-70% RPM for at least one minute before reducing to idle. In hot ambient conditions, it may also be helpful to open engine cowl doors while parked if parking period will be less than one hour. NOTE During idle and after engine shutdown, pilot should uncover one ear and listen for unusual noise which may indicate impending failure of a bearing or other component. CAUTION Do not slow rotor by raising collective during shutdown. Blades may flap and strike tailcone. NOTE HYD switch should be left ON for startup and shutdown to reduce possibility of unintentional hydraulics-off liftoff. Switch OFF only for pre-takeoff controls check or hydraulics-off training. NOTE Rotor brake should be left engaged after shutdown to disable starter buttons and reduce possibility of unintentional starter engagement. ROBINSON MODEL R44 II SECTION 4 NORMAL PROCEDURES FAA APPROVED: 7 MAY 2019 4-15 NOISE ABATEMENT To improve the quality of our environment and to dissuade overly restrictive ordinances against helicopters, it is imperative that every pilot minimize noise irritation to the public. Following are several techniques which should be employed when possible. 1. Avoid flying over outdoor assemblies of people. When this cannot be avoided, fly as high as practical, preferably over 2000 feet AGL. 2. Avoid blade slap. Blade slap generally occurs at airspeeds below 100 KIAS. It can usually be avoided by maintaining 100 KIAS until rate of decent is over 1000 feet per minute, then using a fairly steep approach until airspeed is below 65 KIAS. With the right door vent open, the pilot can easily determine those flight conditions which produce blade slap and develop piloting techniques to eliminate or reduce it. 3. When departing from or approaching a landing site, avoid prolonged flight over noise sensitive areas. Always fly above 500 feet AGL and preferably above 1000 feet AGL. 4. Repetitive noise is far more irritating than a single occurrence. If you must fly over the same area more than once, vary your flight path to not overfly the same buildings each time. 5. When overflying populated areas, look ahead and select the least noise-sensitive route. NOTE Above procedures do not apply where they would conflict with Air Traffic Control clearances or when, in the pilot’s judgment, they would result in an unsafe flight path. INTENTIONALLY BLANK
