How you find this???
To replace one 1/8 inch rivet
- three 1/16 inch rivets would be required.
- two 1/16 inch rivets would be required.
- four 1/16 inch rivets would be required.
I know of no such procedure where this method would be employed please explain
With bleed valves open for anti-ice
- thrust is unaffected.
- thrust decreases, fuel consumption decreases.
- thrust decreases, fuel consumption increases.
Could you please give me some explanation about this, i though when you open bleed valve for anti ice the amount thrust decreases hence engine have to burn more fuel to achieve same thrust before bleed valve is opened
(6 - 2) - (6 - 9) / (-3 + (-3))
- 3 1/2.
- 4.
- 4 1/2.
hey guys bit confused with this :(
Evaluate (3x^2 - 6xy) / (x-2y).
- Cannot be simplified further.
- 3x-3y
- 3x
how you evaluate this?
When the A.P.U is running and pneumatics are on
- bleed valve is closed, surge valve is open.
- bleed valve is open, surge valve is closed.
- bleed valve is open, surge valve is modulating.
explanation plz a bit detailed one thanks !!
When leak testing with a colour contrast field kit, the soak time for a component less than 1/8 in. (3mm) thick would be
- at least twice the normal required soak time.
- at least 3 times the normal soak time.
- at least the standard normal soak time.
I dont get the question.
When reconnecting a H.E.I.U , which cable must be reconnected first?
- It makes no difference.
- T before H.T.
- T before L.T.
Can anybody explain why?
The specific gravity of fuel affects
- thrust rating.
- aircraft range.
- engine efficiency.
PLEASE EXPLAIN.
A ballast resistor is fitted
- in parallel, to give identical readings for all engines.
- in series, to give identical resistance values for all engines.
- in series, to give identical resistance values to all airframes.
explanation?
Turbine engine components are never manufactured by
- electrical resistance welding.
- argon arc welding.
- gas welding.
difference in argon arc and gas welding in regards to turbine engine?
A 10 ohm resistor has a 14.14 V peak drop across it. What power is dissipated?
- 10 W.
- 19.99 W.
- 1.414 W.
how?
In a single mode fibreoptic cable
- several light wave modes can propagate simultaneously through the cable.
- the diameter of the cable is dependent on the wavelength of the light used.
- the distortion of the signal is determined by the total length of cable used.
how is this?
During any stabilised running condition, the spill or half ball valve is
- always varying between fully closed and fully seated.
- lightly seated.
- open fully.
is it similar to bleed valve?
With a fixed throttle in a climb
- RPM will increase.
- RPM will remain constant.
- RPM will decrease.
explaination?

- 70.7 volts.
- 141. 4 volts.
- 63.7 volts.
help please anyone ?
