R22 - Normal Procedures Flashcards
What are the normal procedure airspeeds?
Takeoff and Climb: 60 KIAS Maximum Rate of Climb (Vy): 53 KIAS Maximum Range: 83 KIAS Significant Turbulence: 60-70 KIAS Landing Approach: 60 KIAS Autorotation 60-70 KIAS
What is the normal TAKEOFF PROCEDURE?
- Verify doors latched, governor ON, and RPM stabilized at 102% to 104%.
- Clear area. Slowly raise collective until aircraft is light on skids. Reposition cyclic as required for equilibrium, then gently lift aircraft into hover.
- Lower nose and accelerate to climb speed following profile shown by height-velocity diagram in Section 5. If RPM drops below 102%, lower collective.
What is the Normal Procedure for CRUISE?
- Adjust carb heat if required. (See page 4-11)
- Verify RPM near top of the green arc.
- Set manifold pressure as desired with collective. Observe MAP and airspeed limits.
- Pull RT TRIM knob
- Verify gauges in the green arc and warning lights are out.
What precautionary measures should be taken when encountering turbulence?
Reduce power and use a slower than normal cruise speed. If turbulence is significant or becomes uncomfortable for the pilot, use 60 to 70 KIAS.
Why should you always avoid ever inadvertently pulling fuel mixture?
Engine stoppage will results (For this reason, in-flight leaning with engine mixture control is not recommended)
Is DOORS-OFF operation permitted?
Yes. Operation with both doors off is permitted. If only one door is removed, the left should be kept on to avoid anything falling out and hitting the tail rotor. If both doors are off, warn passenger to secure loose objects and to keep head and arms inside cabin to avoid high-velocity airstream.
What is the normal procedure for PRACTICE AUTOROTATION - POWER RECOVERY?
- Adjust carb heat if required. (See page 4-11)
- Lower collective to down stop and reduce throttle as desired for tachometer needle separation.
- Adjust collective to keep rotor RPM within limits and adjust throttle for tachometer needle separation.
- Keep airspeed 60 to 70 KIAS
- 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 aircraft and raise collective to control descent. Add throttle if required to keep RPM in green arc.
Why is it no longer an acceptable practice to “chop” the throttle when practicing autorotations?
In order to avoid inadvertent engine stoppage. Instead, always roll throttle off smoothly. (Recover immediately if engine is rough or engine RPM continues to drop)
What happens to the governor if RPM drops below 80%?
The governor is inactive below that setting, regardless of switch position.
What extra measure should be taken when entering autorotation from above 4,000 feet?
Reduce throttle slightly before lowering collective in order to prevent overspeed.
What is the normal procedure for PRACTICE AUTOROTATION - WITH GROUND CONTACT (Full down auto)?
If a full-down auto is required for demonstration purposes, perform in the same manner as power recovery autorotations, except:
Prior to cyclic flare, roll throttle off into overtravel spring and hold it 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
Carburetor ice is most likely to form under what circumstances?
When the OAT is between -4 and 30 C and the difference between the OAT and the dew point is less than 15 C.
What is the normal procedure for the Use of CARB HEAT?
During run-up: Use full carb heat (it is filtered) during warm-up to preheat induction system.
During takeoff, climb, and cruise: Use carb heat as required to keep CAT gauge indication out of the yellow arc.
During descent and autorotation: At power settings below 18” MAP, apply full carb heat regardless of CAT gauge indication.
What is the normal procedure for DESCENT, APPROACH, AND LANDING?
- Reduce power with collective as desired. Adjust carb heat as required. Observe airspeed limits.
- Make final approach into wind at lowest practical rate of descent with initial airspeed of 60 knots.
- Reduce airspeed and altitude smoothly to hover. (Be sure rate of descent is less than 300 FPM before reducing airspeed below 30 KIAS)
- From hover, lower collective gradually until ground contact.
- After initial ground contact, lower collective to full-down position.
What is the CAUTION regarding descent with forward cyclic?
Never initiate a descent with forward cyclic because it can produce a low-G condition. Always initiate a descent by lowering collective.
