From the center of gravity, what direction does weight always act?
Towards the center of the earth
Lift is mainly caused by:
pressure differential between the top of the wing and the bottom of the wing
What is the name of the line between the leading edge and trailing edge?
The angle of attack is:
the angle between the relative wind and the chord line of the wing
During flight under smooth air, relative wind is produced by:
Correct flight path of the airplane
In straight and level unaccelerated flight:
lift equals weight and thrust equals drag
The use of flaps:
all of the above
An airplane will stall:
at various airspeeds and pitch attitudes and with any amount of power
As the angle of bank is increased in a level turn, the stalling speed:
The angle of attack at which an airplane wing stalls will
remain the same
If an airplane weighs 3,300lb., what approximate weight would the airplane structure be required to support during a 30o banked turn while maintaining altitude?
Which of these is not a flap?
The phenomenon of ground effect is most likely to result in which problem in an airplane?
becoming airborne before reaching recommended takeoff speed
As the airspeed of the airplane increases:
parasite drag increases
True or False? Angle of Attack and Pitch are the same thing.
Indicate the force acting on an airplane in straight and level flight corresponding to the direction indicated below:
Up - [lift]
Forward - [thrust]
Rearward - [drag]
Down - [weight]
There are 3 types of parasite drag. Complete the fields below. The first letter of each type of parasitic drag is already provided so don't include the first letter in the answer that you provide.
When rolling the airplane into a right bank which aileron is up?
Once an airplane is rolled into a bank it turns because of
the horizontal component of lift
Adverse yaw is a force that is present as an airplane is rolled into or out of a bank and is caused by:
the drag of the downward deflected aileron
In a skidding turn:
the rate of turn is too fast for the amount of bank
If severe turbulence is encountered, the airplane's airspeed should be reduced to
The maximum speed at which the airplane can be maneuvered and a stall will occur before exceeding the limit load factor is:
The ultimate load factor:
both 1 and 2
Asymmetrical thrust (P-factor) is a force caused by
the descending propeller blade producing more thrust
a left turning force caused by the rotational mass of the engine
What determines the longitudinal stability of an airplane?
the location of the CG with respect to the center of lift
What causes an airplane (except a T-tail) to pitch nose down when power is reduced and controls are not adjusted?
the propwash of the elevators is reduced causing a reduction of tail down force.
Match the Axis of Flight with the movement about that axis( lateral , vertical, longitudinal)
Match the control surface that controls movement about the axis of flight: Vertical , Lateral, Longitudinal
What causes an airplane to achieve a sustained climb?
What are the axis of flight? The first letter(s) have been provided for you so complete the answers but don't include the letter(s) already provided.
Lateral, Longitudinal, Vertical
While making a mag check during the runup we are checking
all of the above
If an engine continues to run after the ignition switch is turned to the OFF position, the probable cause may be
a broken magneto ground wire (p-lead)
The basic purpose of adjusting the fuel/air mixture control at altitude is to
decrease the amount of fuel in the mixture in order to compensate for decreased air density
During the runup at a high-elevation airport a pilot notes a slight engine roughness that is not affected by the magneto check, but grows worse during the carburetor heat check. Under these circumstances, which of the following would be the most logical initial action?
check the results obtained with a leaner setting of the mixture control
Carburetor ice can be expected at what temperature and relative humidity ranges?
at temperatures of 20oF to 90oF and a relative humidity of greater than 50%
While flying you have carburetor ice. After applying carburetor heat you should expect
an initial decrease in engine RPM, followed by an increase in engine RPM
If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range, the pilot may have been
operating with too much power and with the mixture set too lean
The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as:
What is the definition of detonation?
explosive burning of the fuel air mixture, which may be caused by too lean a mixture.
The practice of running a fuel tank dry before switching tanks is considered unwise because
the engine-driven fuel pump or electric fuel boost pump may draw air into the fuel system which could cause a vapor lock
Aircraft engines need battery power to produce a spark while in flight.
Proper leaning will result in greater engine efficiency and less spark plug contamination.
Preignition often leads to detonation, is caused by hot spots in the cylinder or too rich of a mixture, and is corrected by leaning the mixture.
What are the four strokes of the internal combustion engine? Complete the information below.
all of the above
You are flying from an area of high pressure to an area of low pressure and you fail to reset your altimeter, therefore the aircraft is:
lower than what your altimeter indicates

Never exceed airspeed is indicated on an airspeed indicator as:
a red line
In a zero wind situation, which airspeed increases as you climb in altitude in a turbocharged airplane?
Flight information that is shown on the artificial horizon (attitude indicator) is:
pitch and bank
How fast is a standard rate turn?
360 degrees in 2 minutes
Airplane A has an airspeed of 100 MPH, airplane B 120 MPH and airplane C 140 MPH. All three airplanes are indicating a standard rate turn on the turn needle. Which airplane has the steepest bank angle?
The angular difference between true and magnetic north
Northerly turning error causes the magnetic compass to either lead or lag. You are turning left to a heading of 180o. Therefore, you should roll out of the turn when the compass reads:
In the Northern Hemisphere, if an airplane is accelerated on a heading of 060º, the magnetic compass will indicate
a turn toward the north
The ADC does not measure raw static and pitot pressure.
If the altimeter has an accurate pressure setting in the Kohlsman window, it will show Mean Sea Level.
Loss of the AHRS will affect the ADC
Deviation is something that we have to correct for when flying an airplane on a cross country.
Which instruments are part of the "ALPA T"?
Correct Attitude Indicator
Correct Heading Indicator
Complete the sentence below. Don't include the letters already provided in the answers that you submit.
In round dial airplanes the al[timeter], ai[rspeed], and v[ertical] s[peed] instruments receive static information.
AHRS Stands for
Attitude Heading Reference System
GCU stands for
Garmin Control Unit
