Aviation Information Flashcards
- How do spoilers differ from airbrakes?
a) Airbrakes increase drag without affecting lift
b) Spoilers increase drag without affecting lift
c) Spoilers decrease drag
d) Airbrakes decrease drag
e) Airbrakes reduce the lift-to-drag ratio
a) Airbrakes increase drag without affecting lift
Unlike airbrakes, spoilers reduce lift and increase drag. Airbrakes only increase drag.
- If the wings of an aircraft are attached to the bottom of the fuselage, what type of design is
this?
a) Mid wing
b) Low wing
c) High wing
d) Shoulder wing
e) Parasol wing
b) Low wing
In low wing aircrafts, the wings are attached to the bottom of the fuselage.
- Which of the acronyms below refers to the total weight of the aircraft as it was manufactured?
a) AUW
b) OEW
c) MEW
d) MLW
e) MRW
c) MEW
The manufacturer’s empty weight (MEW) is the weight of the aircraft as it was built. It includes all systems and parts needed to operate the aircraft. It does not include passengers, baggage, cargo, or fuel.
- Which of the following classes of airspace is considered uncontrolled airspace?
a) Class B
b) Class C
c) Class D
d) Class E
e) Class G
e) Class G
Airspace classes A-E are controlled airspaces. Class G airspace is considered uncontrolled.
- Which of the following types of wing planforms is the most efficient?
a) Rectangular
b) Elliptical
c) Tapered
d) Swept
e) None of the above
b) Elliptical
Elliptical planforms are the most efficient. They create the least amount of drag.
- Wings that are dihedral increase which of the following?
a) Stabilization
b) Drag
c) Cabin pressure
d) Cabin temperature
e) Flight speed
a) Stabilization
Dihedral wings are angled upward. They provide a stabilizing effect on the aircraft.
- In aviation terminology, the term trim refers to which of the following?
a) The desired position of the aircraft
b) The desired location of the ailerons
c) The desired location of the spoilers
d) The desired type of wings
e) The desired type of fuselage
a) The desired position of the aircraft
Trim refers to the desired position of the aircraft.
- Within a horizonal flow of fluid, points of faster fluid speeds will experience _________ points
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) 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.
- 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
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.
- 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
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.
- 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
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.
- 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) 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.
- 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) An engine will have less power
Aircrafts perform more efficiently when air density is high. Cold temperatures contribute to
higher levels of air density.
- 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
d) Profile drag
Profile drag is determined by the shape of the aircraft. Slimmer aircrafts have less of this type
of drag.
- 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
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.
