When checking the turbine section you do not measure
IGT
When doing an anti-ice valve operational check on an F-16C/D before starting the engine you place the anti-ice engine switch to
OFF
Aircraft noise suppressors have how many primary air silencers to help reduce turbine whine?
2
The aircraft noise suppressor shutdown procedure is important because it
ensures the noise suppressor will be operational for the next aircraft
The sidewalls of the hush house test bay is constructed of
air inlet modules
The hush house exhaust deflector is constructed of
small panel modules filled with noise reduction material
Before moving an aircraft into the hush house, you must inspect the aircraft
and its forms
What hush house feature allows flexibility when running an engine that has been removed from the airframe?
The thrust stand slides into position on tracks
When inspecting the hush house, you are not required to check the
engine being tested
In addition to determining the condition of a repaired or overhauled engine, you also test engines
that have been involved in an incident or a mishap
When testing a TF34 engine at test cell, which test ensures that all operating limits and schedules from idle to maximum power are within limits?
Transient check
Which testing engine is equipped with a QEC kit?
TF39-1C
What two types of test cells does the Air Force currently use?
Fixed and portable
Which test cell noise suppressors use water to cool the exhaust gases?
Both fixed and portable
In a fixed test cell, the test bay access doors are sealed to
prevent unwanted noise from getting into the control room
The vertical baffles in the fixed test cell’s exhaust stack are designed to remove
low-frequency sound
The portable test cell is not equipped with a
model 3000 trailer
The basic portable test cell’s thrust trailer rails adjust to a height of
40 inches
the swivel pads at the bottom of the leveling jacks on the engine thrust trailer of the portable test cell provide all the following except
supporting the thrust trailer at a height of 80 inches
The portable test cell’s vibration pickups are cooled by the
pneumatic system
The portable test cell’s noise suppressor is not equipped with
a fuel trailer
