What is one purpose of wing flaps? - Answers -To enable the pilot to make steeper
approaches to a landing without increasing the airspeed.
One of the main functions of flaps during approach and landing is to: - Answers -
Increase the angle of descent without increasing the airspeed.
What is the purpose of the rudder on an airplane? - Answers -To control yaw.
Which is not a primary flight control surface?
A. Flaps
B. Stabilator
C Ailerons - Answers -A. Flaps
The elevator controls movement around which axis? - Answers -Lateral.
Which statement is true concerning primary flight controls?
A. The effectiveness of each control surface increases with speed because there is
more flow over them
B. Only when all three primary flight controls move in sequence do the airflow and
pressure distribution change over and around the airfoil.
C. Primary flight controls include ailerons, rudder, elevator, and trim systems - Answers
-A. The effectiveness of each control surface increases with speed because there is
more flow over them.
Which of the following is true concerning flaps?
A. Flaps are attached to the leading edge of the wing and are used to increase wing lift.
,B. Flaps allow an increase in the angle of descent without increasing airspeed.
C. Flaps are high drag devices deployed from the wings to reduce lift. - Answers -B.
Flaps allow and increase in the angle of descent without increasing airspeed.
Which device is a secondary flight control?
A. Spoilers
B. Ailerons
C. Stabilators - Answers -A. Spoilers
Trim systems are designed to do what? - Answers -They relieve the pilot of the need to
maintain constant back pressure on the flight controls.
The four forces acting on an airplane in flight are: - Answers -Lift, Weight, Thrust, &
Drag
When are the four forces that act on an airplane in equilibrium? - Answers -During
unaccelerated flight.
What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-
and-level flight? - Answers -Lift equals weight.
Thrust equals drag.
Which statement relates to Bernoulli's principle? - Answers -Air traveling faster over the
curve upper surface of an airfoil causes lower pressure on the top surface.
The term "angle of attack" is defined as the angle... - Answers -between the wing chord
line and the relative wind.
Angle of attack is defined as the chord line of an airfoil and the... - Answers -Direction of
the relative wind.
The angle of attack at which an airplane wing stalls will... - Answers -Remain the same
regardless of gross weight.
As altitude increases, the indicated airspeed at which a given airplane stalls in a
particular configuration will... - Answers -Remain the same regardless of altitude.
In what flight condition must an aircraft be placed in order to spin? - Answers -Stalled.
During a spin to the left, which wing(s) is/are stalled? - Answers -Both wings are stalled.
How will frost on the wings of an airplane affect takeoff performance? - Answers -Frost
will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability.
Why is frost considered hazardous to flight? - Answers -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? - Answers -Frost my
prevent the airplane from becoming airborne at normal takeoff speed.
What is ground effect? - Answers -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... - Answers -Less than the length of the wingspan above the
surface.
What must a pilot be aware of as a result of ground effect? - Answers -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? - Answers -Becoming airborne
before reaching recommended takeoff speed.
What force makes an airplane turn? - Answers -The horizontal component of lift.
An airplane said to be inherently stable will... - Answers -require less effort to control.
What determines the longitudinal stability of an airplane? - Answers -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... - Answers -
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... - Answers -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? - Answers -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... - Answers -Less
stable at all speeds.
In what flight condition is torque effect the greatest in a single-engine airplane? -
Answers -Low airspeed, high power, high angle of attack.
The left turning tendency of an airplane caused by P-factor is the result of the... -
Answers -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? - Answers -When at high
angles of attack.
The amount of excess load that can be imposed on the wing of an airplane depends
upon the... - Answers -Speed of the airplane.
Which basic flight maneuver increases the load factor on an airplane as compared to
straight-and-level flight? - Answers -Turns.
During an approach to a stall, an increased load factor will cause the aircraft to... -
Answers -Stall at a high airspeed.
In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward
the north if... - Answers -An aircraft is accelerated while on an east of west heading.
During flight, when are the indications of a magnetic compass accurate? - Answers -
Only in straight-and-level unaccelerated flight.
Deviation in a magnetic compass is caused by the... - Answers -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... - Answers -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... - Answers -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... - Answers -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... - Answers -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? - Answers -The
compass will indicate a turn to the right, but at a faster rate than is actually occurring.
The pitot systems provides impact pressure for what instrument? - Answers -Airspeed
indicator.
Which instrument will become inoperative if the pitot tube becomes clogged? - Answers
-Airspeed.
If the pitot tube and outside static vents become clogged, which instruments would be
affected? - Answers -The altimeter, airspeed indicator, & vertical speed indicator.
