The emitter, base and collector currents in a common emitter circuit, follow ohm"s and kirchoff"s law, which is
- Ie = Ic - Ib.
- Ib = Ie + Ic.
- Ie = Ib + Ic.
Please write your comment here.the ans is wrong its 1b+1e-1c
The electrical A/H has a movement of
- 85 degree in pitch and roll
- 360 in roll and 110 in pitch
- 360 in roll and 85 in pitch
A/H or A/P?
A cockpit check on the engine firewire system is a
- continuity check.
- calibration check.
- function check.
is this answer is correct bcoz i have study somewhere that firewire check is a check for continuity of the loop..........please can anyone help me regarding it........
thanks guys.....
Avdel rivets are closed by
- a broaching process.
- a tapered mandrel.
- a squeezing process.
broaching process ?
A micro-shaver is used to
- cut rivets to the required length before forming.
- mill the rivet head after forming.
- trim the rivet shank diameter before installation.
What is Mill the revit Head?.
A Silver coated conductor in an unpresurised area is subject to moisture and has a damaged coating would be likely to cause
- Wet Arc Tracking.
- Silver Migration.
- Red Plague.
plz explain the Question and answer
How is a D.T.I. initially set up?
- The gauge plunger should be fully extended and then the needle zeroed.
- The gauge plunger should be partly depressed and the needle zeroed.
- The needle should be zeroed first, then the plunger fully extended.
plz explain how gauge plunger should be partly depresed and needle zeroed in D.T.I
A DAC uses a precision amplifier to
- ensure the output voltages remain accurate.
- compensate for input resistor temperature.
- ensure the input voltage remains accurate.
any body explain.......... How
Galvanic action caused by dissimilar metal contact may best be prevented by
- applying a non-porous dielectric material between the surfaces.
- special precautions are not required if they are properly bonded.
- priming both the surfaces with a light coat of zinc chromate primer.
I agree with this answer but would a jointing compound not be the best method?
The Mass of a Proton is approximately
- approximately 500 times the mass of an electron.
- equal to approximately half the mass of a neutron.
- 2000 times greater than the mass of an electron.
mass of proton is = mass of an electron thats the answer ?
The 5th coloured band on a resistor represents the
- reliability or temperature coefficient.
- tolerance.
- multiplier.
then what is 4th colored band for????
In a full wave bridge rectifier
- the output is pure DC. Frequency is 0 Hz.
- the output frequency is twice the input frequency.
- the output voltage is twice the input voltage.
Don't get confused guys, without a smoothing circuit the o/p is not a pure dc, and correct answer have to be in this case: "the output frequency is twice the input frequency". if i'm wrong plz, don't hesitate to prove it :D
What is the area of the shape shown, in square centimeters?
- 1000
- 1130
- 1264
In answer unit is not given here
What is the area (including the ends) of a cylinder diameter 10 cm and 10 cm in height?
- 50pi
- 100pi
- 150pi
PLEASE EXPLAIN
ACARS is an acronym for
- Airframe Communicating Addressing and Reporting System.
- Airborne Communicating Addressing and Reporting System.
- Aircraft Communicating Addressing and Reporting System.
its Aircraft Communicating Addressing and Reporting System, as per AIRBUS
Weight is equal to
- mass * acceleration.
- mass * gravity.
- volume * gravity.
gravity=mass×acceleration which is 9.8m/s＊s,the correct should be A
In the circuit shown, the power developed across the 10 kilo ohm resistor is
- 250 mW.
- 250 W.
- 50 mW.
Please Explain 250mW as answer
When the weight of an aircraft increases, the minimum drag speed
- decreases.
- increases.
- is unaffected.
can anyone clarify this? thanks :)
The power required at low altitude for a given IAS is
- unchanged with altitude.
- higher.
- lower.
Power is dependant on TAS and not IAS
Power =velocity *drag
When testing EGT probe
- it must be soaked and ambient temperature allowance taken into consideration.
- not necessarily soaked but ambient temperature must be taken into consideration.
- if not soaked, the standard ambient temperature of 15 degrees C is assumed.
please explain
Inwards relief valves usually open at a negative differential pressure not exceeding
- 0.16 p.s.i.
- 1.2 p.s.i.
- 0.5 p.s.i.
I thought it should be 0.5 psi
Low wing loading
- increases stalling speed, landing speed and the landing run.
- increases lift, stalling speed and overall maneuverability.
- decreases stalling speed, landing speed and landing run.
what is low wing loading
ARINC 429 SDI word format is at bits
- 1-32.
- 1-10.
- 9-10.
somthing wrong with option A ?
(6 - 2) - (6 - 9) / (-3 + (-3))
- 3 1/2.
- 4.
- 4 1/2.
How is this possible?
(6 - 2) - (6 - 9) / (-3 + (-3))
=4-(-3)/(-6)
=7/(-6)
=?
111.2 MHz is
- VHF.
- VOR.
- ILS.
VOR frequency 112-118 MHz
ILS frequency 108-112 MHz(all odd frequencies).
so,the only correct answer must be VHF(108-136 MHz).
