What color lights are used for a landing pad - ✔✔combination of green, yellow, white
lift differential that exists between the advancing main rotor blade and the retreating
rotor blade is known as? - ✔✔Dis-symmetry of lift
to maintain the desired hovering altitude (no wind conditions ) you must? - ✔✔change
the amount of main rotor thrust
Density altitude at sea level is - ✔✔29.92 inHg (inches of mercury) at 15 degrees C
What is created by the motion of an airfoil through the air - ✔✔relative wind
when departing behind a heavy aircraft the pilot should avoid wake turbulence by
maneuvering the helicopter - ✔✔Above and upwind from the heavy aircraft
What actions should you take if engine failure occurs at altitude? - ✔✔lower the
collective pitch control to maintain rotor RPM
during a hover, a helicopter tends to drift right. to compensate for this some
helicopters? - ✔✔rotor mast is rigged to the left side
if the rpm is low and manifold pressure is high what initial corrective action should be
taken? - ✔✔lower the collective pitch

,high air speeds especially in turbulent air should be avoided because the possibility of ?
- ✔✔the retreating blade to stall in forward flight, stalls are more likely to occur under
conditions of high gross weight, low rpm, high density altitude, steep or abrupt turns,
and or turbulent flight.
translation lift is the result of? - ✔✔Airspeed
during surface taxi the collective pitch is used to control? - ✔✔the rate of speed. the
higher the collective pitch the higher the taxi speed.
the upward bending of the rotor blades resulting from the combination of lift and
centrifugal forces is known as - ✔✔coning
the tail rotor produces thrust and is variable through the use of ? - ✔✔anti torque pedals
medium frequency vibrations would be associated with - ✔✔defects in tail rotor
while in cruise level flight, low frequency vibrations (100-400 cycles per minute) are
usually associated with? - ✔✔always associated with the main rotor
a stall is the results of ? - ✔✔exceeding the angle of attack
What is ground effect ? - ✔✔the result of interference of the surface
the primary purpose of the tail rotor system is to ? - ✔✔counteract the torque effect of
the main rotor
the most effective method of scanning for other aircraft for collision avoidance during
daylight hours is to use ? - ✔✔a series of short regularly spaced eye movements that
bring successive areas of the sky into the central visual field each movement should not
exceed 10 degrees and each area should be observed for at least one second to enable
detection
translation lift is the result of ? - ✔✔increased rotor efficiency

, in a no wind condition, which control is used to change heading? - ✔✔cyclic control
a helicopter that is improperly loaded with a CG forward of forward limits will ? -
✔✔*have a nose low altitude * need excessive rearward displacement of the cyclic to
maintain hover
the wind conditions that requires the most caution when avoiding wake turbulence on
landing is - ✔✔light tail winds because they can move the vortices of a preceding
aircraft forward into the anticipated touch down zone of another
when operating at high forward air speeds, retreating blade stall are more likely to
occur under which conditions? - ✔✔high gross weight, low rpm, high density altitude,
steep or adrupt turns, and or turbulent flight
to initiate a quick stop ? - ✔✔aft the cyclic and simultaneously lower the collective pitch
if possible when departing from a defined area what type of take off is preferred? - ✔✔a
normal take off from a hover should be made in confined areas
under what conditions should a pilot consider using a running take off? - ✔✔when
gross weight or density altitude prevents a sustained hover at normal hovering altitude.
this is often referred to as high density altitude takeoff
ground effect is most likely to result in what - ✔✔becoming airborne before reaching
appropriated speeds.
what action would be appropriate for confined area operations ? - ✔✔plan a flight path
over an area suitable for a forced landing
ground resonance is most likely to develop when? - ✔✔a series of shocks causes the
rotor system to become unbalanced ie hard contact with one skid
lift is the upward thrust created by ? - ✔✔airflow as it passes around an airfoil
