What are compressor stalls 1) Excessive AoA on the compressor
caused by? 1) Excessive AoA blades
on the compressor blades 2)
An uncontrolled loss of bleed
air from any part of the
aircrafts pneumatic system 3)
The low rotational speed of the
low pressure compressor 4)
The turbine section(s) unable
to extract sufficient energy
from the exhaust to drive the
compressor section
What is the sole purpose of 3) To prevent compressor stalls
compressor bleed valves? 1)
To provide cold air for air
conditioning 2) To provide hot
air to be sent through a heat
exchanger and then to the
mixing box 3) To prevent
compressor stalls 4) To
prevent an over pressurization
in the compressor during start
up

An engine's bypass ratio is: 1) 1) The ratio of air which bypasses
The ratio of air which bypasses the engine to air that passes
the engine to air that passes through the combustion chamber
through the combustion
chamber 2) The ratio of air
that enters the high pressure
turbine to air that enters the
low pressure turbine 3) The
, ratio of air that enters the
engines fan to air that exits in
the form of exhaust 4) The
ratio of air that bypasses the
combustion chamber to air
that passes through the bleed
air valve
A "hung start" occurs when: 1) 2) The engine lights up normally, but
The engine lights up normally, the RPM does not reach ideal speed
however the starter does not (N2)
cut out 2) The engine lights up
normally, but the RPM does
not reach ideal speed (N2) 3)
The engine does not light up
due to incorrect fuel
scheduling 4) The engine does
not light up due to N1
stagnation
The pressure inside a 3) Regulating the outflow of
pressurized aircraft is pressurized air from the cabin via
controlled by: 1) Regulating the outflow valves
the amount of bleed air drawn
in from the compressor via the
engine bleed air valve 2)
Regulating the dump valves 3)
Regulating the outflow of
pressurized air from the cabin
via the outflow valves 4)
Regulating the inflow of
pressurized air into the cabin
