Low G Pushover
Gentle Aft Cyclic and the correct the roll if necessary
Maximum Glide Distance
Airspeed 90 KIAS
Rotor Rpm 90%
Loss of tail rotor thrust in forward flight
Indicated by a nose right yaw
- Immediately enter auto rotation
- Maintain at least 70 KIAS if practical
- Select landing site roll off throttle and perform autorotation landing
Loss of tail rotor thrust in hover
- Immediately roll off throttle and allow aircraft to settle
- Raise collective just before touchdown
Oil light
Check tachometer and oil pressure gauge if pressure is lost land immediately
MR Temp
Indicates excessive temperature of main rotor gearbox
If light is accompanied by any indication of a problem such as a noise vibration or temperature rise land immediately
MR Chip
Indicates metallic particles in Main rotor gearbox
If light is accompanied by any indication of a problem such as a noise vibration or temperature rise land immediately
TR chip
Indicates metallic particles in tail rotor gearbox
If light is accompanied by any indication of a problem such as a noise vibration or temperature rise land immediately
Low fuel
Indicates approximately 3 gallons of usable fuel remaining engine will run out of fuel after 10 minutes
Aux fuel pump
Indicates low auxiliary fuel pump pressure if no other indication of a problem land as soon as practical if light is accompanied by erratic engine operation land immediately
Fuel filter
Indicates fuel strainer contamination. If no other indication of a problem, land as soon as practical. If light is accompanied by aux fuel pump warning light or erratic engine operation, Land immediately.
Clutch light
If light comes on in flight and does not go out within 10 seconds pull clutch circuit breaker and land as soon as practical and prepare for an autorotation
Transponder inspected every?
24 months
ELT needs inspected?
Every Year
Batteries changed at half their life or 1 continuous hour used
Private pilot can change things such as Oil. What needs to go in maintenance records for that change?
Date, description of what was done, Private pilot cert # & Expiration, Hobbs time.
Category, class, type & Series of aircraft used
Rotorcraft, Helicopter, Robinson R-44 Raven II
Semi rigid Rotor means
Blades flap as a unit on a teeter
Fully articulated
Each blade can flap on their own,
Rigid System
Flap by bending
Advancing blade flaps which direction
Upward due to the relative wind, to decrease AoA
What can you do with 3rd class medical
Operate as Private pilot, Flight Instructor
Cord Line
A straight line connecting the leading and trailing edges of the airfoil. Separates upper and lower camber
Angle of attack is defined as
Angle between the wing chord line and the relative wind - wind relative to the air foil.
Robinson blades
12 years / 2200 hours
3 Types of Airmets
Sierra IFR
Tango turbulence and wind
Zulu Ice
How far to stay away from a thunderstorm
Never closer than 5 miles, but if possible stay at least 20 miles away
Settling with Power
Vortex Ring State
Less than ETL
20 to 100% of power
300 or more fpm
Memory aid for LOW RPM Recovery
Roll on throttle , Lower collective
What would cause excessive coning of blades
Excessive weight and low rpms
Critical angle of dynamic rollover
5-8 degrees
LTE Causes
Due to wind or fast right pedal turns, Low rpm, high gross weight & density altitude. Helicopter yaws uncontrollably to the right. Fixed by forward flight or hover auto
Stuck left pedal
Normal to steep approach
Don’t autorotate
