What condition will cause an airfoil to stall? - Correct Answers The critical angle of attack is exceeded.
What condition describes best glide speed? - Correct Answers The speed at which total drag on the
aircraft is at a minimum.
How does an airfoil produce lift? - Correct Answers An airfoil bends air over the upper surface and
deflects it downward at the trailing edge as downwash, the action of the downwash creates the equal
and opposite reaction of lifting the airfoil up.
Which best describes the flight control characteristics of an aircraft designed to have negative static
lateral stability? - Correct Answers Once the aircraft is rolled in either direction the aircraft will continue
to roll in that direction until stopped.
Which of the following best describes ground effect? - Correct Answers The ability to fly within about a
wingspan of the surface at a reduced airspeed due to the reduced affects of upwash, downwash and
wingtip vortices.
Select the best response that describes the methods a pilot can use to control the amount of lift
generated by the wing of an airplane while in flight. - Correct Answers Angle of Attack, airspeed, high
lift devices
Which response best describes the four forces when an airplane is established in a steady constant
airspeed climb? - Correct Answers Lift is equal to weight and thrust is equal to drag.
Which response best describes the four forces when an airplane is established in a steady constant
airspeed descent? - Correct Answers Lift is equal to weight and thrust is equal to drag.
In order for a Cessna 172 to have the longitudinal stability it was designed to exhibit the longitudinal
positioning of the CG and Center of Lift must be: - Correct Answers CG must be in front of the Center of
Lift, this allows for tail down force from the horizontal stabilizer to maintain longitudinal stability.
,As load factor increases stall speed increases because: - Correct Answers The wings are required to
support more force to maintain flight resulting in exceeding the CAOA at a higher airspeed.
In a normally aspirated airplane why does Vmc speed decreases with an increase in altitude? - Correct
Answers As altitude increases above sea level the available power decreases, reducing the force
required to maintain zero side slip.
What effect does an increase of bank angle into the operative engine have on Vmc speed? - Correct
Answers As bank angle increases Vmc speed decreases.
During engine inoperative flight what precautions should be taken if the rudder trim is utilized to relieve
the rudder control pressures? - Correct Answers Any changes in operative engine power will require the
trim setting to be adjusted.
Explain the relationship of stall speed to VMC speed. - Correct Answers Stall speed remains relatively
the same with an increase in altitude as VMC speed decreases with an increase in altitude, this causes a
multi-engine airplane with an inoperative engine to encounter a yaw coupled roll at lower altitudes and
a stall at higher altitudes if speed is reduced while flying.
When practicing the Vmc Demonstration, a stalled condition - Correct Answers Will lead to the loss of
control of the airplane and potentially the inability to recover from the situation.
How is the critical engine computed for published VMC speed, how is it changed, and what effect on the
published speed and aircraft control does it have? - Correct Answers Critical engine is computed
inoperative, changed to operative which reduces VMC speed and provides increased control ability.
How is weight computed for published VMC speed, how is it changed, and what affect on the published
speed and aircraft performance does it have? - Correct Answers Weight is computed at max gross
takeoff weight, change is a reduction in weight which increases VMC speed and increases performance.
Define VMC. - Correct Answers VMC is the minimum speed at which positive control can be maintained
about all three axis of a multi-engine airplane with the critical engine rendered inoperative and no more
than five degrees of bank.
, What is Vsse? - Correct Answers The minimum speed in which an engine should be suddenly simulated
inoperative.
When flying a multi-engine airplane with the critical engine inoperative, what is the purpose for using
the zero side slip control method? - Correct Answers Zero side slip places the relative wind parallel to
the longitudinal axis of the airplane, reducing drag, and provides the best control ability for the airplane.
Which of the following is true about the use of vortex generators? - Correct Answers Vortex generators
add turbulence to the boundary layer aiding in laminar flow down the chord of the wing reducing drag
as a result.
Conventional twin engine airplanes have greater left turning tendencies than singe engine airplanes
because both engines are creating torque and p-factor that want to turn the airplane left. - Correct
Answers True
Zero degrees sideslip is a condition when... - Correct Answers the longitudinal axis of the airplane is
aligned with the relative wind and the horizontal component of lift created has an effective force against
the operating engine.
Asymmetrical thrust in a conventional twin engine airplane is caused by? - Correct Answers Anytime
thrust output of a powerplant is not equal to the thrust of the other, inappropriate power application,
mechanical failure, or powerpalnt inefficiencies are all possible examples.
Addition of power at the onset of a stall in a conventional multi engine airplane creates induced flow
over the wings further deepening the stall. - Correct Answers False
Twin engine airplanes with counter rotating propellers have the following effect. - Correct Answers
Elimination of asymmetric thrust and torque with both engines operating.
The four factors that determine a critical engine are torque, p-factor, spiraling slipstream, and... -
Correct Answers Accelerated slipstream (induced flow)
Banking beyond five degrees into the operative engine during engine inoperative flight has what effect?
- Correct Answers An increase in controllability but a decrease in performance.
What condition describes best glide speed? - Correct Answers The speed at which total drag on the
aircraft is at a minimum.
