Answer✔✔-the NOTAR
how would high density altitude affect the performance of a helicopter - Answer✔✔-Performance would
decrease due to low value of the air density

rotor blades individually and cynically
AOA is - Answer✔✔-ANGLE OF ATTACK and the airfoil chord line and the resultant relative wins

what three conditions are necessary for a helicopter to be in danger of a dynamic rollover - Answer✔✔-
pivot point, rolling motion, and exceeding critical angle
what are the three regions of a rotor in autorotaton - Answer✔✔-driven, driving, and stall
what is resultant relative wind - Answer✔✔-Rotational relative wind modified by induced flow
Bernoulli's Principle - Answer✔✔-as the velocity of a fluid increases, the pressure exerted by the fluid
decreases
which is true of helicopter performance in ground effect (IGE) - Answer✔✔-the rotor system becomes
more efficient since the ground interiors with the circulation pattern and less oiler is required to hover
which term is used to describe the weight of an aircraft, including all hydraulic and oil systems, full,
trapped and unusable fuel and all fixed equitment - Answer✔✔-basic weight or basic empty weight
what aerodynamic condition can occur when a helicopter is descending at greater then 300 fpm, has 20
to 100 percent power, and an airspeed less then effective translational lift - Answer✔✔-settling with
power
how would a pilot recognize the onset of transverse flow effect - Answer✔✔-during takeoff, a vibration
and a right rolling motion occurs as the aircraft acerbates through 10 to 20 knots
if magnetic north is a positive 15 degree variation west from true north to convert true north to
magnetic north when flying eastbound what is the adjustment a pilot must make to the magnetic
compass - Answer✔✔-add 15 degrees
as air becomes less dense, it causes the following change in force - Answer✔✔-a reduction in power at
the engine intakes
