    of slower fluid speed.

a) Less pressure than
b) Greater pressure than
c) Less weight than
d) Greater weight than
e) The same level of pressure as

A

a) Less pressure than

According to Bernoulli’s Principle, within a horizontal flow of fluid, points of higher fluid speed
will have less pressure than points of slower fluid speed.

Q
  1. The operating empty weight of an aircraft includes which of the following?

a) Passenger weight
b) Crew weight
c) Baggage weight
d) Cargo weight
e) Useable fuel

A

b) Crew weight

The operating empty weight (OEW) of an aircraft includes the manufacturer’s empty weight
(MEW) plus the weight of the crew and the fluids and equipment necessary for flight. The OEW does not include any passengers, their baggage, or useable fuel.

Q
  1. The flight envelope encompasses the limits of speed, altitude, and __________ required to
    maintain a stable flight.

a) Air pressure
b) Lift
c) Angle of attack
d) Temperature
e) Maximum weight

A

c) Angle of attack

The flight envelope includes the limitations of speed, altitude and angle of attack needed to
keep the aircraft stable during flight.

Q
  1. If the maximum takeoff weight is exceeded, which of the following may occur?

a) The runway distance required for liftoff may be decreased
b) The power required for takeoff may be increased
c) Stress on the aircraft structure may be decreased
d) Distance required for taxi may be increased
e) The amount of fuel needed for flight may be decreased

A

b) The power required for takeoff may be increased

In the event that the maximum takeoff weight (MTOW) is exceeded, the aircraft may require more power in order to take off. It may also require a longer runway distance and may place additional stress on the aircraft.

Q
  1. Assume the pilot of an aircraft does not reset the pressure altimeter after departing an
    airfield. Which of the following is most likely to occur?

a) The aircraft may be at a lower altitude than what the altimeter displays
b) Aircraft cabin pressure may be higher than what the altimeter displays
c) The altimeter will automatically show the pressure altitude of the destination airfield
d) It is not necessary to reset the pressure altitude indicator upon departure
e) Air traffic controllers will notify the pilot that their altitude is incorrect

A

a) The aircraft may be at a lower altitude than what the altimeter displays

Upon departure, the pilot must reset the pressure altimeter to reflect the correct pressure altitude for the destination airfield. If the pilot fails to reset the pressure altimeter, the
aircraft may be at a higher/lower altitude than the altimeter displays when it arrives at the destination airfield.

Q
  1. How might low air density affect engine performance?

a) An engine will have less power
b) An engine will have more power
c) Engine performance remained unaffected
d) Engine performance is negatively affected only in cold weather
e) Engine performance is positively affected only in hot weather

A

a) An engine will have less power

Aircrafts perform more efficiently when air density is high. Cold temperatures contribute to
higher levels of air density.

Q
  1. What type of drag is primarily produced by the shape of the aircraft?

a) Parasite drag
b) Skin friction
c) Interference drag
d) Profile drag
e) Induced drag

A

d) Profile drag

Profile drag is determined by the shape of the aircraft. Slimmer aircrafts have less of this type
of drag.

Q
  1. Which type of propeller allows the pilot to adjust the blade pitch during flight?

a) Fixed pitch propeller
b) Variable pitch propeller
c) Pusher propeller
d) Both fixed and variable pitch propellers
e) Both fixed and pushed propellers

A

b) Variable pitch propeller

Pilots can adjust blade pitch during flight when flying aircrafts equipped with variable pitch
propellers. Blade pitch is set by the manufacturers in aircrafts with fixed pitch propellers.

Q
  1. Which of the following are part of the vertical tail structure?

a) The elevators
b) The spoilers
c) The rudder
d) The horizonal stabilizer
e) The ailerons

Q
  1. Complete the following statement: When an aircraft is turned, the vertical lift component
    must ________ the weight of the aircraft in order to return to level flight.

a) Exceed
b) Equal
c) Be less than
d) Be half of
e) Be twice than

A

b) Equal

For an aircraft to return to level straight-and-level flight, the vertical lift component must equal the weight of the aircraft.

Q
  1. Regarding aircraft right-of-way, which of the following statements is true?

a) When two aircrafts approach head-on, the pilots of the aircraft should change course to the left
b) When an aircraft is being overtaken, the pilot of an aircraft being overtaken has the right-of-way
c) When two aircrafts are landing at the same time, the aircraft at a higher altitude has the right-
of-way
d) Airplanes have the right-of-way over hot air balloons
e) An aircraft in tow has the right-of-way over a helicopter

A

e) An aircraft in tow has the right-of-way over a helicopter

An aircraft in tow has the right-of-way over any other engine-driven aircrafts, including
rotorcrafts.
