In an Arinc 429 Word label-representing heading is 320, this is represented in bits 1- 8 as
- 01011001.
- 00001011.
- 01101000.
HOW???
The ratio of 6:4 can also be expressed as
- 64%.
- 66%.
- 150%.
Can anyone tel me this how?
The blood/alcohol limit is
- 40 milligrams of alcohol per 100 millilitres of blood as the single universal limit applying equally to commercial aircrew, air traffic controllers and all maintenance engineers.
- 20 milligrams of alcohol per 100 millilitres of blood as the single uniform limit for commercial aircrew, air traffic controllers and licensed aircraft maintenance engineers alike.
- 20 milligrams of alcohol per 100 millilitres of blood for commercial aircrew, air traffic controllers and 80 milligrams of alcohol per 100 millilitres of blood for maintenance engineers.
i read in cap 715 that its 20mg per 100ml of blood. can anyone one confirm?
Who is most likely to deviate from standard procedure?
- Young, inexperienced man.
- Over confident, young man.
- Fatigued, experienced man.
why
Dividing 4 1/2 by 2 1/6 gives the answer of
- 54/26.
- 25/12.
- 21/3.
pls anyone.. calculate for goodness sake
What is 738 in binary coded decimal?
- 1011110010
- 111100010
- 11100111000
what bullshit is this?
A fire detection system that operates on the rate of temperature rise is a
- thermocouple system.
- thermal switch system.
- continuous loop system.
Why not "continuous loop system"?
Minor surface damage located in a repairable area, but not on the leading or trailing edges of aluminium blades, may be repaired by first
- filing with a half round or flat file.
- sanding and applying a proper filler.
- filing with a riffle file.
now am torn between two answers. previously the system gave me the answer to be sanding and applying a proper filler and now it is saying the right answer is filing with a riffle file.which one is the correct answer?
When governor spring load is less than governor weights, the CSU is in
- overspeed.
- underspeed.
- normal.
how? i dont get it
The purpose of the pitch change cams is to
- convert rotary motion to linear motion.
- prevent windmilling.
- convert linear motion to rotary motion.
is it not for changing rotary to linear?
Transfer of heat from a hot area to a cold area is
- conduction.
- convection.
- refraction.
Area should be defined for this question.
if solid yes your answer is right otherwise all 3 choices are correct.
Manifold pressure is measured
- at inlet port above and below ambient conditions
- at inlet port above and below standard atmosphere at sea level
- at inlet port indicating boost pressure
at inlet port above and below standard atmosphere at sea level....
If a manifold pressure gauge is measuring in a supercharged engine it will measure above 29.92 in Hg.If the supercharge is not use it will measure below that figure. EHJ Pallett Integrated Instruments Page-355
When using a test set to test an EGT thermocouple circuit
- no compensation for ambient temperature is required
- only consider ambient temperature compensation if the ambient temperature is over 20oC
- always compensate for ambient temperature
Always compensate for ambient temperature....
To test the system the test set has to be trimmed for ambient temperature,as the system when in operation is adjusted for ambient temperature by the compensating resistor.This is stated in B 737 AMM.
The ISA
- defines a standard atmosphere model.
- is referenced from the equator.
- is taken from 45 degrees latitude.
I think The ISA assume a standard day is the right answer
How is the efficiency of a turbo prop engine assessed?
- By correcting propeller RPM for ambient Air temperature and barometric pressure.
- By comparing compressor and propeller RPM against a reference figure.
- By comparing torque meter pressure against a reference figure.

After placing an engine in an M.V.P envelope
- check humidity indicator after 12 hours.
- check humidity indicator after 24 hours.
- check humidity indicator after 48 hours.
What is M.V.P?
Supervisory E.E.C sends its output to the
- fuel valve.
- H.M.U/F.F.G.
- EGT thermocouple circuit.
What is M.U/F.F.G.?
What is the advancing blade on a helicopter doing?
- Going to the highest point.
- Increasing in lift.
- Increasing in drag.
please tell me answer
Why is the hydromechanical governor fitted to a gas turbine engine fuel pump?
- To enable the engine to operate over a wide range of fuel SGs.
- To enable efficient control of fuel flow to be maintained at altitude.
- To enable the engine to operate over a wide range of fuel flow.
What is SGs?
Small cuts in a M.V.P. engine storage bag can be repaired
- with adhesive PVC tape.
- by vulcanising.
- by replacing M.V.P.
What is M.V.P.?
When testing an E.G.T system
- the O.A.T is always taken into consideration.
- the O.A.T is neglected.
- O.A.T is only taken into consideration when over20degreesC.
What is O.A.T?
E.I.U ignitor plugs receive their electrical supply from
- discharge inductor.
- starter system electrical circuit.
- discharge capacitor.
What is "E.I.U"?
A fuel or oil fire is defined as a
- class B fire.
- class C fire.
- class A fire.
So What depend to class A fire (and "C")?
What is 738 in binary coded decimal?
- 1011110010
- 111100010
- 11100111000
Can anyone tell me that how this answer come?
How is engine oil usually cooled?
- By a fuel/oil cooler.
- By ram air.
- By bleed air.
I thought the primary purpose of the fuel/oil heat exchanger was to heat the fuel, and ram air through the oil cooler was the primary oil cooling medium. Any thoughts?
