AVIA 340- EXAM ONE (CH 1-4.5)
QUESTIONS AND CORRECT ANSWERS
(VERIFIED ANSWERS) A GRADE
____________ occur most often at low power settings and can
result in a decrease in RPM and potentially an engine shutdown.
- correct answer- engine flame out
A __________ -flow compressor slings air to the outside,
90degrees, compressing it in to a diverging chamber known as a
diffuser; most only have one per engine. This type of compressor
is less efficient than the other kind and used on aircraft that
might operate on unimproved airfields. - correct answer-
centrifugal
A diode allows electricity to flow in only one direction in an
electrical circuit. - correct answer- True
A Ground Power Unit (GPU) provides power for ground
operations and extra thrust for takeoff, - correct answer-
False
, A hot start can occur when - correct answer- the battery
is weak
A volt is best described as - correct answer- a basic unit
of electrical pressure
A Watt is a measure of electrical POWER. - correct answer-
True
An ampere is the unit used to measure electric current -
correct answer- True
An intergrated drive generator is simply a generator connected
to a ________ which acts as an automatic gearbow to maintain a
constant generator AC frequency output regardless of engine
RPM. - correct answer- constant speed drive unit (CSD)
During normal operations, turbopropeller aircraft use what as
the primary source to slow down after landing? - correct
answer- propeller blades
