Describe Recirculation correct answers Increase of Induced airflow due to recirculation of A/C
downwash.
*15ft. clearance from all obstructions.*
Describe Over Pitching/Rotor RPM Droop correct answers Loss of rotor thrust when
approaching or during hover due to over pitching & Rotor RPM decrease.
Recover:
Collective - Lower
Airspeed - Increase
*Always check your daily performance limits*
Describe Transverse Flow Effect correct answers A reduction of induced airflow at the front of
the disc during forward flight increases lift. But, due to gyroscopic effect its 90 degrees later in
rotation causing a roll to the right.
*Left lateral cyclic during transition.*
Describe Retreating Blade Tip Stall correct answers Excessive flapping due to a reduction in
VTA caused by an increase of reverse flow size/ Aircraft velocity. Aircraft pitches up & Rolls
towards retreating blade (Right).
Recover:
Collective - Lower
Cyclic - Aft & lateral to level
Airspeed - Maintain lower A/S
*Know the Vne*
Describe Low-G Right Roll correct answers Low/Negative G situations result in a lack of
aerodynamic forces capable of balancing the tail rotor thrust which will result in Left Yaw and a
roll right
Recover:
,Cyclic - Immediate, gentle aft to reload the rotor disk. Then lateral cyclic to level the ship.
Describe Settling with Power correct answers Insufficient lift to arrest the aircrafts decent.
*500fpm MAX final approach*
(Can be the early signs of Vortex Ring State)
Describe Vortex Ring State correct answers A/C settling into its own downwash causing
buffeting, sloppy controls, and high rate of decent for flight attitude.
Recover:
Collective - Lower 2 inches
Cyclic - Forward to gain A/S
(Requires powered flight, high rate of decent and low A/S)
A/C Uncontrolled Yaw correct answers Left - Engine Failure Right - Tail Rotor Failure
*Always Enter Autorotation*
Describe Tail Rotor Drift & Roll correct answers Tail rotor drift (Translating Tendency) is caused
by compensating for the uneven forces in the main rotor torque couple with left cyclic.
This causes tail rotor roll which must be compensated with right A/C weight distribution, Tail
rotor pylon, or offset Main rotor
Required Documents correct answers A - airworthiness cert.
R - radio operators licence
R - registration
O - p.O.h
W - weight and balance
I - insurance
L - licence
,L - log book
Describe Translational Lift correct answers Additional lift gained through airspeed or wind
because of increased efficiency of the rotor system.
