the direct oil pressure guage on a test cell is connected to an engine oil pressure line. this configuration will indicate oil pressur with out using wiring, indicator, or

the test cell exhaust gas temperature EGT selector allows selection of

when properly adjustted the accuracy of the test cell N1 and N2 speed indicator will be within

the test cell IC temp indicator displays temps in degrees fahrenheit with a range of

what type of vibration causes unneccessary engine removals and unwarranted repairs

what kind of engine vibration does not persist, but comes and goes

during vibration analysis, frequency is usually measured in

forces acting to create vibration in a jet engine present a highly complex pattern. this is becuase the main rotor

during vibration analysis, why is it necessary to measure all parameters to identify a vibration source

the two types of transducers used to measure vibration are

which type of vribration transducer is made up of certain ceramic compounds and natural crystals

the filter selector switch on the vibration analyzer is used to

what is used to support the fan and low pressure turbine

what procedure is used to ensure the fan and low pressure turbine are correctly balanced

the carbon seal tester simulates the effects of

the engine remote trimmer enables you to adjust

when connected to the engine, what piece of f100 engine test equipment becomes an engine electronic control

which piece of test equipment is used to troubleshoot a jet fuel starter problem on an f-16

you can find written instructions for safe flight line vehicle operations in

the term trim means to adjust the engine systems for optimum performance per the limits in the TO. There are two methods used to trim an engine. they are

the pressure gauges used for an oil system pressure checks are connected at the

when checking the turbine section, you do not measure

which f-16 operational chech allows you to start the jet fuel starter without advancing the throttle to idle or supplying fuel to the aircraft

prior to starting the engine when doin and anti-ice operational check on an f-16 place the anti-ice engine swith to

how many primary air silencers are there on aircraft noise suppressors to help reduce turbine whine

where are the primary silencers positioned on an aircraft noise suppressor

to how many minutes should engine operation in afterburner be limited when the engine is operated in the aircraft noise suppressor

the hush house exhaust deflector is constructed of

before moving an aircraft into the hush house, you must inspect the aircraft

after running an engine in augmentation in the hush house, the augmentor tube is cooled by running the engine at idle for a period of

during an inspection of the hush house you are not required to check

in addition to determining the condition of a repaired or overhauled engine, you also test engines

when testing a TF34 engine at test cell, which test is performed to ensure all operating limits and schedules from idle to maximum power are within limits

which testing engine is equipped with a quick engine change QEC kit

the two types of test cells currently used in the AF areq

a portable test cell is not equipped with a

engines are mounted in the fixed test cell on a thrust stand or are suspended

in the fixed test cell, air for the engine intake comes through baffles located on the

the vertical baffles in the exhaust stack of the fixed test cell are designed to remove

the portable test cell is not equipped with a

on the portable test cell, the swivel pads at the bottom of the leveling jacks on the engine thrust trailer provide for all of the following except

the vibration pickups on the portable test cell are cooled by

the noise suppressor at a portable test cell is not equipped with

when an engine arrives for a test run at the test cell, it must

during an inspection, compressor blade defects that are within limits are

defects such as cracks found during combustion chamber borescope inspections

on a disassembled engine, a visual inspection the combustion chamber is preferred over a borescope inspection becuase
