the angle of descent without increasing airspeed.
Which device is a secondary flight control?
A. Spoilers
B. Ailerons
C. Stabilators - ✔✔A. Spoilers
Trim systems are designed to do what? - ✔✔They relieve the pilot of the need to maintain constant

Thrust equals drag.
Which statement relates to Bernoulli's principle? - ✔✔Air traveling faster over the curve upper surface
of an airfoil causes lower pressure on the top surface.

will... - ✔✔Remain the same regardless of altitude.
In what flight condition must an aircraft be placed in order to spin? - ✔✔Stalled.
During a spin to the left, which wing(s) is/are stalled? - ✔✔Both wings are stalled.
How will frost on the wings of an airplane affect takeoff performance? - ✔✔Frost will disrupt the
smooth flow of air over the wing, adversely affecting its lifting capability.
Why is frost considered hazardous to flight? - ✔✔Frost spoils the smooth flow of air over the wings,
thereby decreasing lifting capability.
How does frost affect the lifting surfaces of an airplane on takeoff? - ✔✔Frost my prevent the airplane
from becoming airborne at normal takeoff speed.
What is ground effect? - ✔✔The result of inference of the surface of the earth with the airflow patterns
about an airplane.
Floating caused by the phenomenon of ground effect will be most realized during an approach to land
when at... - ✔✔Less than the length of the wingspan above the surface.
What must a pilot be aware of as a result of ground effect? - ✔✔Induced drag decreases; therefor, any
excess speed at the point of flare may cause considerable floating.
Ground effect is most likely to result in which problem? - ✔✔Becoming airborne before reaching
recommended takeoff speed.
What force makes an airplane turn? - ✔✔The horizontal component of lift.
An airplane said to be inherently stable will... - ✔✔require less effort to control.
What determines the longitudinal stability of an airplane? - ✔✔The location of the CG with respect to
the center of lift.
Changes in the center of pressure of a wing affect the aircraft's... - ✔✔Aerodynamic balance and
controllability.
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... - ✔✔Difficulty in
recovering from a stalled condition.
What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not
adjusted? - ✔✔The downwash on the elevators from the propeller slipstream is reduced and the
elevator effectiveness is reduced
Loading an airplane to the most aft CG will cause the airplane to be... - ✔✔Less stable at all speeds.
In what flight condition is torque effect the greatest in a single-engine airplane? - ✔✔Low airspeed, high
power, high angle of attack.
The left turning tendency of an airplane caused by P-factor is the result of the... - ✔✔Propeller blade
descending on the right, producing more thrust than the ascending blade on the left.
When does P-factor cause the airplane to yaw to the left? - ✔✔When at high angles of attack.
The amount of excess load that can be imposed on the wing of an airplane depends upon the... -
✔✔Speed of the airplane.
Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level
flight? - ✔✔Turns.
During an approach to a stall, an increased load factor will cause the aircraft to... - ✔✔Stall at a high
airspeed.
In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward the north if... -
✔✔An aircraft is accelerated while on an east of west heading.
During flight, when are the indications of a magnetic compass accurate? - ✔✔Only in straight-and-level
unaccelerated flight.
Deviation in a magnetic compass is caused by the... - ✔✔Magnetic fields within the aircraft distorting
the lines of magnetic force.
In the Northern Hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will
normally indicate... - ✔✔Correctly when on a north or south heading.
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the west
if... - ✔✔A right turn is entered from a north heading.
In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward the south when...
- ✔✔The aircraft is decelerated while on a west heading.
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the east
if... - ✔✔A left turn is entered from a north heading.
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? - ✔✔The compass will indicate a turn to the right,
but at a faster rate than is actually occurring.
