Compared with the flap down configuration the maximum angle of attack for the flaps up configuration is
- smaller.
- larger.
- unchanged.
Could please anyone explain this question?
A restrictor in the landing gear hydraulic retraction and lowering system is positioned in the
- landing gear down line.
- return line from the landing gear selector.
- landing gear up line.
Why? i though it will be positioned in the lowering line to damping landing gear extention due to aerodynamics loads.
log 100/2 =
- 1
- log 98
- log 200
how do you work this out?
60 mm expressed as a percentage of 3 meters is
- 0.5%.
- 1.8%.
- 2%.
How do you work this out?
Choose the correct statement
- cosec^2 * x - cot^2 * x = 1
- sec^2 * x + tan^2 * x = 1
- cos^2 * x - sin^2 * x = 1
Can anyone explain this?
A blueprint shows a hole of 0.3751 to be drilled. What fraction size drill bit is most nearly equal?
- 3/16
- 5/16
- 3/8
how to solve
If the frequency to a capacitor increases, the current through it
- decreases.
- increases.
- is zero.
if the formula for capacitive reactance is 1/2piFC
then as frequency increases capacitive reactance would decrease
this would in turn allow more current to flow?
An example of a paramagnetic material is
- silver.
- iron.
- glass.
- aluminium.
Surely this is incorrect too.
iron would fall into the ferromagnet group
silver would fall into the diamagnetic group
glass would fall into the paramagnetic group
The average value of 100 volts peak AC is
- 70.7 volts.
- 141. 4 volts.
- 63.7 volts.
I think this might be incorrect.
i assume the question is looking for the rms value?
the formula for rms is -
peak voltage x 0.707
or
peak voltage / 1.414
both formulas give 70.7 as the answer
am i missing something?
When aligning an aircraft for a compass swing, the maximum allowable error is
- 1 degrees.
- 3 degrees.
- 5 degrees.
Why?
A fuel flow transmitter requires a motor or a synchronous motor to have a
- constant voltage within small tolerances
- constant frequency within small tolerances
- low EMF as it is immersed in fuel
Can someone please explain.
An increase in fuel flow through the impeller type fuel flow transmitter is measured by
- drum lags impeller
- impeller lags turbine
- decreasing angle between the two
Can someone please explain.
As a subsonic aircraft speeds-up, its Centre of Pressure
- moves aft.
- moves forward.
- is unaffected.
explanation please?
To check the structure of a wing
- ultrasound NDT methods are used.
- high voltage X-rays are used.
- low voltage X-rays are used instead.
low voltage x rays are used
One lamp is connected across corresponding phases of two alternators. They will be synchronised when
- the lamp is extinguished.
- the lamp is either at maximum brightness or is extinguished.
- the lamp is maximum brightness.
hi, someone could explain me this question? tks
A radial is referenced
- from a beacon.
- to a VOR.
- on a compass.
Why isn't VOR ?
Which of the graphs shown is given by the equation; y = 2x^3 + 4x + 3?
- a
- b
- c
how does it come to c?
A major mod is carried out. The C of A
- is suspended until the mod is carried out and the time is added on to the C of A.
- is not effected.
- becomes invalid.
BECOMES INVALID ........ IF IT IS MAJOR DEFECT ????????
The capacitance of a varactor diode is
- inversely proportional with reverse bias voltage.
- a linear function of applied reverse bias voltage.
- directly related to the forward bias voltage.
As reverse voltage increases, depletion layer and therefore capacitance increases proportionally. Am I missing something here?
If an aircraft is yawing left, the trim tab on the rudder would be positioned
- to the right, deflecting the rudder left.
- back to its neutral centre position.
- to the left, moving the rudder right.
Wrong!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Due to the interference of the airflow on a high wing aircraft between the fuselage and the wings, the lateral stability of the aircraft in a gusty wind situation will cause
- the upper wing to increase its lift.
- the upper wing to decrease its lift.
- the lower wing to decrease its lift.
uhmm more detailed explanation plz?
A free turbine is
- not directly connected to the power output shaft.
- connected directly to the propeller and compressor.
- connected directly to the power output shaft.
how is a free turbine connected to power output shaft
What airworthiness notice applies to propellers used on British registered aircraft?
- 4.
- 14.
- 75.
should be AN75
When working on aircraft, the consumption of alcohol
- is permissible as long as the blood alcohol level stays under the standard driving limit.
- you cannot work on aircraft even 8 hours after consuming large quantities of alcohol.
- is acceptable in small amounts before a shift as long as you feel fit to carry out tasks.
Isn' t it 80 mg per 100 ml of blood ?
