When are the four forces that act on an airplane in equilibrium? correct answers during
unaccelerated flight
When landing behind a large aircraft, which procedure should be followed for vortex avoidance?
correct answers stay above its final approach flightpath all the way down to touchdown
what force makes an airplane turn? correct answers The horizontal component of lift.
Wingtip vortices are created only when an aircraft is correct answers developing lift
what is the purpose of the rudder on an airplane? correct answers To control yaw.
When landing behind a large aircraft, the pilot should avoid wake turbulence by staying? correct
answers above the large aircrafts final approach path and landing beyond the large aircrafts
touchdown point
(refer to figure 4) what is the caution range of the airplane? correct answers 165 to 208 KTS
As altitude increases, the indicated airspeed at which a given airplane stalls in a particular
configuration will correct answers remain the same regardless of altitude
the condition that requires maximum caution when avoiding wake turbulence on landing is a
correct answers light, quartering tailwind
How does the wake turbulence vortex circulate around each wingtip? correct answers outward,
upward, and around each tip
an airplane said to be inherently stable will correct answers require less effort to control
what is the relationship of lift, drag, thrust, and weight when the airplane is in straight and level
flight? correct answers lift equals weight and thrust equals drag
in what flight condition must an aircraft be placed in order to spin? correct answers stalled
the angle between the chord line of an airfoil and the relative wind is known as the angle of
correct answers attack
(refer to figure 4) Which color identifies the power off stalling speed in a specified
configuration? correct answers lower limit of the green arc
, (refer to figure 1) The acute angle A is the angle of correct answers attack
An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One
undesirable flight characteristic a pilot might experience with this airplane would be correct
answers difficulty in recovering from a stalled condition
When departing behind a heavy aircraft, the pilot should avoid wake turbulence by maneuvering
the aircraft correct answers above and upwind from the heavy aircraft
which V speed represents maximum landing gear extended speed? correct answers VLE
the angle of attack at which an airplane wing stalls will correct answers remain the same
regardless of gross weight
changes in the center of pressure of a wing affect the aircrafts correct answers aerodynamic
balance and controllability
(refer to figure 4) the maximum speed at which the airplane can be operated in smooth air is
correct answers 208 KTS
How does frost affect the lifting surface of an airplane on takeoff? correct answers frost may
prevent the airplane from becoming airborne at normal takeoff speed
(refer to figure 4) which color identifies the normal flap operating range? correct answers the
white arc
the amount of excess load that can be imposed on the wing of an airplane depends upon the
correct answers speed of the airplane
(refer to figure 4) which marking identifies the never exceed speed? correct answers the red
radial line
When taking off or landing at an airport where heavy aircraft are operating, one should be
particularly alert to the hazards of wingtip vortices because this turbulence tends to correct
answers sink into the flightpath or aircraft operating below the aircraft generating the turbulence
which V speed represents maneuvering speed? correct answers VA
the speed at which a single flight control can be moved, one time, to its full deflection without
risk of damage to the aircraft is correct answers maneuvering speed
