- 3750pi cm^2
why?
When maintaining level flight an increase in speed will
- cause the C of P to move aft.
- cause the C of P to shift forward.
- have no effect on C of P position.
when increase in speed, basically lift increases. so the c of p move forward what!! sorry if i'm incorrect!

The equalizing coils on voltage regulators will
- have current passing through them from the higher loaded generator to the lower.
- have current passing through them only when the generators are not paralleled.
- be connected to each other when the generators are paralleled.

In typical vapour cycle system, the sub-cooler
- cools the vapour further to prevent slugging.
- is a heat exchanger to superheat the vapour.
- delivers extra cooling effect when the aircraft is on ground.
option 1 is the most correct answer?!

200 kilovolts can be expressed as
- 2 * 10^3 volts.
- 2 * 10^4 volts.
- 2 * 10^5 volts.
how do we come up with this answer
In a Turn and Slip indicator, the effect of increasing the rotor speed would be
- it would have no effect.
- it would under read.
- it would over read.
MAY BE IT IS WRONG SINCE MORE SPEED MEANS MORE FORCE IS REQUIRED TO MOVE SO UNDERREAD
Laser gyros have
- no rotating parts.
- moving parts.
- a spinning rotor.
may be it is wrong ,since nothing moves except beam of light which is weightless
In a jack with a ram only on one side and hydraulic fluid applied from both sides
- the ram will remain stationary, since equal hydraulic fluid pressures cancel on both sides of it.
- the ram will move away from the side where the ram is due to pressure on differential areas.
- the ram will move to the side where the ram is, due to pressure acting on differential areas.
surly if the ram takes up say 2 sq in and the jack piston has area of say 6 sq in, the piston minus ram area will be 4 sq in. Giving an overall advantage to the bare piston face equivelent to 2 sq in (the area of the ram) with equal pressure there is a net unbalanced force onthe bare piston face thus pushing it to the side were the ram is. Please explain how this is wrong?
Whenever possible a functional test should be carried out on an aircraft using which power supply?
- The aircraft battery.
- The aircraft generators.
- An external supply.
anyone got a reference for this question? i would have thought best option is to use the aircraft generators where possible as you would then be checking the entire system.
A helicopter tail rotor is fitted to
- counteract engine torque and provide a rapid turn facility.
- counteract main rotor torque and provide normal directional control.
- permit directional control.
Please write your comment here.may be it is to counter main rotor torque and not engine torque ans ist seems more appropriate
On large aircraft, braked wheel assemblies are normally inflated with
- nitrogen.
- nitrogen and not more than 5% of air.
- an argon and CO2 mixture.
refer to JAR 25.733 Tyres (e)
tyres mounted on brakedwheels must be inflated with dry nitrogen or other gases shown to be inert so that the gas mixture inthe tyre does not contain oxygen in excess of 5% by volume..
nitrogen and not more than 5% of air, will be more correct?
The life of an aircraft oxygen cylinder is
- 4 years.
- 10 years.
- 2 years.
As i know the oxygen cylinder are removed for overhaul and tested is every 4 year
so life of an aircraft oxygen cylinder is 4 years also?! or 5 years will be the most correct answer?
The Janus beam is for
- working out acceleration
- levelling the aerial
- to compensate for attitude changes
Please check this answer.I suppose first answer is correct.

What is the principle of an O2 generator?
- Sodium chlorate and iron mixed by an electronic detonator.
- Sodium chlorate and iron using a mechanical detonator producing O2 when mixed with air.
- Sodium chloride and iron mixed by an electronic detonator.
iron mixed by an electronic detonator or iron using a mechanical detonator?!
