23
Q

name the four basic constructional features of an AMAD

A

housing assembly, geartgrain, lubrication system, and a 50% engine cutout switch assembly

24
Q

where is the totoal temperature sensor (Tt2) located on a F199-PW-100 engine?

A

inside the fan inlet guide vane case at the 5:30 positoin

25
How does the exhaust nozzle position indicating system sense the position of the exhaust nozzle?
through a mechanical linkage between the nozzle actuator motor and the exhaust nozzle position transducer
26
engine operation is controlled automatically by what componet
speed switch control
27
what must be done if an aircraft exceeds the programmed depot maintenance cycle by 90 days
the red dash will become a red x unless the SM grants a extension
28
a cold compressor stall that occurs at low RPM and is accompanied by a slight over temperature is called
a partial
29
what is the rate of spark in an AE2100D3 exciter
four to seven sparks EACH second
30
The shutdown procedure for the aircraft noise suppressor is important because it
ensures that the noise suppressor is not damaged by improper engine shutdown procedures
31
What type of force used during pitchlock of the 54H60-117 propeller prevents the blades for decreasing pitch
centrifugal twisting moment
32
what are the three locations for running an engine that is installed on the airframe
on the flight line, at the trimpad, and (for fighers) in the hush house
33
the AE2100D3 power unit accessory drive(PUAD) is mounted on the bottom of the
forward end of gearbox mounted accessory drive (GMAD)
34
during an engine run, what signs would indicate a possible compressor stall?
a rise in exhaust gas temperature, loss of thrust, fluctuating fuel flow, and failure of rpm to increase when the throttle is advanced
35
when inspecting the outer edge of a failed turbine rotor disk, you find a dark, semicircular area. what dose this indicate
that a crack was present prior to failure
36
what is the most probable cuawe of a flameout of a jet engine flying at 40,000 feet with a constant engine revolution of 50%
the rpm is to low
37
where is the no.2 bearing located in the F119-PW-100 engine
intermediate case
38
during jet engine decelration, a hydromechanical fuel control schedules fuel flow as a function of
burner pressure
39
what is an advantage of shorter oil sampling intervals
the GREATER probability that initial evidence of failures will be detected
40
why do jet fuels tend to ice up at higher altitudes?
because of the extremely low temperatures and the hight viscosity of jet fuels, wheich prevents adequate settling of water droplets at low temp
41
if an aircraft dosnt fly for more than 30 consecutive days, what type of inspection must be performed>
a BPO or if no BPSs exist, perform a HSC or equivalent inspeciton
