Aviation Knowledge Quiz

Which is a purpose of ground spoilers?

• Reduce the wings' lift upon landing

• Aid in rolling an airplane into a turn

• Increase the rate of descent without gaining airspeed

A lightening hole in a rib:

• collects and disposes of electrical charges

• provides a means of passing cables and controls through a pressure bulkhead

• lightens and stiffens the structure

• prevents lightning strikes damaging the fuselage

A restrictor valve is physically fitted in the:

• U/C up line and flap up line

• supply line to the U/C retraction actuator

• U/C down line and flap up line

• U/C down line and flap down line

A relief valve:

• relieves at its designed pressure

• maintains pressure to a priority circuit

• relieves below system pressure

• prevents excessive pressure through increased fluid temperature

For which purpose may flight spoilers be used?

• Increase the rate of descent without increasing aerodynamic drag

• Reduce the wings' lift upon landing

• Aid in longitudinal balance when rolling an airplane into a turn

The primary purpose of high-lift devices is to increase the...

• lift at low speeds

• drag and reduce airspeed

• L/D

The primary purpose of the fuselage is to:

• provide access to the cockpit

• house the crew and payload

• keep out adverse weather

With air in the hydraulic system you would:

• allow the accumulator to automatically adjust itself

• bleed the air out of the system

• expect it to operate faster

• ignore it because normal operation would remove it

What effect does the leading-edge slot in the wing have on performance?

• Decreases profile drag

• Decelerates the upper surface boundary layer air

• Changes the stalling angle of attack to a higher angle

The Maximum Zero Fuel Mass (MZFM) of an aircraft is:

• the maximum permissible mass of an aircraft with no usable fuel

• the maximum permissible take-off mass of the aircraft

• the maximum permissible mass of an aircraft with zero payload

• the maximum permissible landing mass
