What type of intake is one that decreases gradually in area and then increases?
- Convergent.
- Convergent / Divergent.
- Divergent.
isnt this divergent only?Why can it be also convergent?I think convergent is the opposite of what it says.
The velocity of supersonic air as it flows through a divergent nozzle
- decreases.
- increases.
- is inversely proportional to the temperature.
why is it increasing?It isnt convergent,it is divergent.Can someone help?
Gas pressure through the turbine section will generally
- increase.
- remain the same.
- decrease.
y is it decrease?
Power is adjusted in a gas turbine engine by
- increasing fuel flow.
- increasing air and fuel flow.
- increasing airflow to the combustion chamber.
How exactly is the air flow increased? Is it not the case that to draw more air into the engine, the compressor needs more power which needs more power output from the turbine which means higher fuel flow first.
A radial is referenced
- from a beacon.
- to a VOR.
- on a compass.
radial is for VOR and bearing for beacon. right?
During a climb from a dive
- the thrust required is greater than required for level flight.
- the thrust required is lower than for level flight.
- the thrust required is the same as for level flight.
plz explain
The atmospheric zone where the temperature remains fairly constant is called the
- stratosphere.
- ionosphere.
- troposphere.
Please explain
A wing develops 10,000N of lift at 100knots. Assuming the wing remains at the same angle of attack and remains at the same altitude, how much lift will it develop at 300knots?
- 900,000N.
- 90,000N.
- 30,000N.
how to calculate??
Downward displacement of an aileron
- increases the stalling angle of attack for that wing.
- decreases the angle at which its wing will stall.
- has no effect on its wing stalling angle, only on stalling speed.
how come aileron effect the stall?
On a high winged aircraft, what effect will the fuselage have on the up-going wing?
- The up-going wing will have a decrease in angle of attack and therefore a decrease in lift.
- The down-going will have a decrease in angle of attack and therefore a decrease in lift.
- The up-going wing will have an increase in angle of attack and therefore a decrease in lift.
can someone please explain this?I thought it was c
In a bank, the weight is
- increased.
- decreased.
- unchanged.
Why?
The reason for sharp leading edged wings on high speed aircraft is to
- enable the shockwave to be accurately positioned.
- enable the shockwave to be pushed aft and reduce wave drag.
- reduce the laminar boundary layer thickness on the wing surface.
Please explain
The temperature to which humid air must be cooled at constant pressure to become saturated is called
- relative humidity.
- dew point.
- absolute humidity.
i think the answer is about humidity..
so its between absolute humidity and ralative humudity
Lift is generated by a wing
- mostly on the bottom surface.
- mostly on the top surface.
- equally on both the top and bottom surfaces.
why is it mostly on the top and not on the bottom?Shouldn't it be the bottom?
The induced drag of an aircraft
- increases if the aspect ratio is increased.
- decreases with increasing speed.
- increases with increasing speed.
can somewone explain this
An anti-balance tab is used
- to relieve hinge loads on the controls.
- for trimming the aircraft during cruise flight.
- to give more feel to the controls.
i dont understand should i learn it by heart?
For an aircraft climbing at a constant IAS the Mach number will
- increase.
- decrease.
- remain constant.
help!!
What is the collective term for the fin and rudder and other surfaces aft of the centre of gravity that helps directional stability?
- Empennage and vertical stabiliser.
- Forward fuselage keel area.
- Effective keel surface.
why not empennage?I got really confused with this question.
A stall warning device must be set to operate
- at a speed just above stalling speed.
- at a speed just below stalling speed.
- at precisely the stalling speed.
bollocks
An increase in the Ram Ratio of an intake will
- have no effect upon the temperature of the compressed air.
- increase the temperature of the compressed air.
- decrease the temperature of the compressed air.
I think the answer "C" or "3" is correct.
If the speeder spring pressure of a CSU is increased the blade will
- coarsen off.
- fine off.
- will not move.
Isn't speeder spring pressure increased by the flyweights moving out? Therefore this is overspeed condition - blades coarsen?
In a two position propeller
- ATM turns the prop to fine.
- oil pushes the prop to fine.
- oil pushes the prop to coarse.
Hi friends,can someone please explain this answer for me?
Thank you!
In what position is the constant-speed propeller control placed to check the magnetos?
- Full decrease, low propeller blade pitch angle.
- Full increase, low propeller blade pitch angle.
- Full increase, high propeller blade pitch angle.
what are magnetos?
The purpose of using reverse pitch propellers is to
- provide aerodynamic breaking.
- allow aircraft to taxi backwards.
- reverse the direction of rotation of the propeller.
isnt the B also right?
The function of a propeller pitch lock is to prevent the propeller from
- coarsening.
- reducing below flight fine pitch.
- fining off in the event of pitch lock mechanism failure.
So the PITCH LOCK stops the propeller from fining off when the PITCH LOCK fails, does that make any sense at all?
