Test Bank Solution Manual for Private Pilot EOC Already Passed
(Refer to Figure 7.) How should a pilot determine the direction of bank from an attitude indicator such
as the one illustrated?
A. By the direction of deflection of the banking scale (A).
B. By the direction of deflection of the horizon bar (B).
C. By the relationship of the miniature airplane (C) to the deflected horizon bar (B). - Answers C
The relationship of the miniature aircraft C to the horizon bar B is the same as the relationship of the
real aircraft to the actual horizon.
Answer (A) is incorrect because the bank scale shows degrees, and not direction of bank. Answer (B) is
incorrect because the horizon line deflects opposite the direction of turn, in order to correct horizon
representation.
(Refer to figure 62.) In flying the rectangular course, when would the aircraft be turned less than 90°?
A.
Corners 1 and 4.
B.
Corners 1 and 2.
C.
Corners 2 and 4. - Answers A
The airplane will turn less than 90 degrees at corners 1 and 4. At corner 1, the airplane turns to a
heading that is crabbed into the wind, which makes the turn less than 90 degrees. At corner 4, the
airplane is crabbed into the wind when the turn is started, and the turn will be less than 90 degrees.
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
A.
a longer takeoff run.
B.
difficulty in recovering from a stalled condition.
C.
,stalling at higher-than-normal airspeed. - Answers B
Loading in a tail-heavy condition can reduce the airplane's ability to recover from stalls and spins. Tail-
heavy loading also produces very light stick forces, making it easy for the pilot to inadvertently
overstress the airplane.
Answer (A) is incorrect because an airplane with an aft CG has less drag from a reduction in horizontal
stabilizer lift, resulting in a short takeoff run. Answer (C) is incorrect because an airplane with an aft CG
flies at a lower angle of attack, resulting in a lower stall speed.
If a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in
indication?
A.
Altimeter will indicate .15" Hg higher.
B.
Altimeter will indicate 150 feet higher.
C.
Altimeter will indicate 150 feet lower. - Answers C
When the knob on the altimeter is rotated, the altimeter setting pressure scale moves simultaneously
with the altimeter pointers. The numerical values of pressure indicated in the window increase while the
altimeter indicates an increase in altitude, or decrease while the altimeter indicates a decrease in
altitude. This is contrary to the reaction on the pointers when air pressure changes and is based solely
on the mechanical makeup of the altimeter. The difference between the two settings is equal to 0.15"
Hg (30.11 - 29.96 = 0.15). At the standard pressure lapse rate of 1" Hg = 1,000 feet in altitude, the
amount of change equals 150 feet.
What force makes an airplane turn?
A.
The horizontal component of lift.
B.
The vertical component of lift.
C.
Centrifugal force. - Answers A
,As the airplane is banked, lift acts horizontally as well as vertically and the airplane is pulled around the
turn.
Answer (B) is incorrect because the vertical component of lift has no horizontal force to make the
airplane turn. Answer (C) is incorrect because the centrifugal force acts against the horizontal
component of lift.
What determines the longitudinal stability of an airplane?
A.
The location of the CG with respect to the center of lift.
B.
The effectiveness of the horizontal stabilizer, rudder, and rudder trim tab.
C.
The relationship of thrust and lift to weight and drag. - Answers A
The location of the center of gravity with respect to the center of lift determines to a great extent the
longitudinal stability of an airplane. Center of gravity aft of the center of lift will result in an undesirable
pitch-up moment during flight. An airplane with the center of gravity forward of the center of lift will
pitch down when power is reduced. This will increase the airspeed and the downward force on the
elevators. This increased downward force on the elevators will bring the nose up, providing positive
stability. The farther forward the CG is, the more stable the airplane.
Answer (B) is incorrect because the rudder and rudder trim tab control the yaw. Answer (C) is incorrect
because the relationship of thrust and lift to weight and drag affects speed and altitude.
(Refer to Figure 6.) To receive accurate indications during flight from a heading indicator, the instrument
must be
A.
set prior to flight on a known heading.
B.
calibrated on a compass rose at regular intervals.
C.
periodically realigned with the magnetic compass as the gyro precesses. - Answers C
, Because the heading indicator is run by a gyroscope instead of a magnetic source, precession will cause
creep or drift from a heading to which it is set. It is important to check the indications frequently and
reset the heading indicator to align it with the magnetic compass when required.
Answer (A) is incorrect because they don't do anything to correct for precession in flight. Answer (B) is
incorrect because they don't do anything to correct for precession in flight.
To properly purge water from the fuel system of an aircraft equipped with fuel tank sumps and a fuel
strainer quick drain, it is necessary to drain fuel from the
A.
fuel strainer drain.
B.
lowest point in the fuel system.
C.
fuel strainer drain and the fuel tank sumps. - Answers C
Many aircraft are equipped with fuel strainers located at the lowest point in the fuel lines and sump
drains installed at the lowest point in each fuel tank. In order to completely purge all of the liquid water
from the fuel system, the fuel strainer drain and the sumps in all of the tanks must be drained.
What should be the indication on the magnetic compass as you roll into a standard rate turn to the right
from a south heading in the Northern Hemisphere?
A.
The compass will initially indicate a turn to the left.
B.
The compass will indicate a turn to the right, but at a faster rate than is actually occurring.
C.
The compass will remain on south for a short time, then gradually catch up to the magnetic heading of
the airplane. - Answers B
If you are on a southerly heading and roll into a standard-rate turn to the right, the compass will
immediately indicate a turn toward the west (to the right) because of the northerly turning error. During
the first part of the turn, it will show a faster rate of turn than you are actually making.
Answer (A) is incorrect because the compass will initially indicate a turn to the left when rolling into a
standard rate turn from a north heading in the Northern Hemisphere. Answer (C) is incorrect because
(Refer to Figure 7.) How should a pilot determine the direction of bank from an attitude indicator such
as the one illustrated?
A. By the direction of deflection of the banking scale (A).
