- 20 degrees C and 760 mmHg.
- 15 degrees C and 760 mmHg.
who is willing to explain for me this question
The landing speed of an aircraft is 54 m/s. If the maximum deceleration is 3m/s2 the minimum length of runway required is
- 162m.
- 486m.
- 360m.
solve pls
If you apply this waveform to this circuit, what is the output across the capacitor?
- Pulsed negative
- Pulsed positive
- Zero
can someone explain?
Formation of white crystals of potassium carbonate on a properly serviced Ni-cd battery indicates
- over charged.
- full charged.
- under charged.
why old batteries wich were too much discharged produce white crystas?
A permit to fly is valid
- for 12 months.
- until the date stated on it.
- only for evaluating a modification.
The permit to fly si valid for 14 days maximum or until The date Stated on it
Which of the following is typical of the number granted to an approved organization under BCARs
- A N/0000/67.
- A I/0000/103.
- A I/0000/83.
what is the difference between choice B and C?
When is a Noise Certificate required to be carried aboard the aircraft?
- At all times.
- When flying in UK airspace only.
- When flying in UK or any EU member state airspace.
Why not at all times?
An EASA approved maintenance organisation in the category B rating, is approved to carry-out maintenance on
- aircraft.
- engines.
- aircraft and engines.
why only on engines?
Aircraft components require overhauls at times stated in the
- maintenance schedule.
- overhaul manual.
- maintenance manual.
Must be maintenance schedule as maintenance manual has only procedure not time limits.
Aircraft above 5700 kg are weighed
- every five years.
- four years after manufacture thereafter every nine years.
- at manufacture then after 2 years then every 5 years after manufacture.
The requirement for re-weighing an aircraft under JAR-OPS is
at manufacturer and then four yearly intervals.
which one is correct? pls explain
A NAND gate has inputs A and B and output C. If the output was zero, what are the inputs?
- A=1 B=1.
- A=0 B=0.
- A=1 B=0.
EXPLAIN PLS
An Airworthiness Directive carried out to an engine of American construction fitted to British built aircraft below 5700 kg M.T.W.A. would be certified in
- The Engine Log Book.
- The Aircraft Log Book.
- The modification record book.
wat diff aircraft log book n tech log book
How many people sign a CRS after scheduled maintenance?
- Two, one for mechanical activities and one for the avionics.
- One in each category.
- One only.
one person signs for A&C part and 1 for Avionics. Then how is the answer "one only"
A Dial Test Indicator may be used for
- checking a round bar for bow.
- checking dimensions to within 0.125 inch.
- checking any known depth measurement.
D.T.I why isnt the 3d option?Because it says "any"?
A shunt is used with
- an ammeter.
- a voltmeter.
- an ohmmeter.
please explain
What non-destructive testing method requires little or no part preparation, is used to detect surface or near-surface defects in most metals, and may also be used to separate metals or alloys and their heat-treat conditions?
- Eddy current inspection.
- Magnetic particle inspection.
- Ultrasonic pulse inspection.
isnt eddy current inspecction method only for internal cracks?Why does it mention here that it is used to detect"surface and nearsurface"?
When tapping blind holes
- a set of three taps is used.
- a set of two taps is used.
- a single bottoming tap is used.
what does 3 taps mean?
A crimped electrical connection is suspected to be high resistance. How would you verify this without disconnecting the circuit?
- Measure the millivolt drop across the connection with a millivolt meter.
- Check the resistance across the connection using an ohmmeter.
- Apply a 250 volt megger test across the crimped terminal.
how to measure with an millivolt meter without disconnecting the circuit?!!!
Galvanic corrosion refers to a type of
- corrosion between two pieces of material.
- electrochemical plating process between metal layers.
- uniform surface corrosion across the exposed area.
"two pieces of material" - this is a sloppy question - one piece of "material" could be plastic and the other metal!
When drilling out a rivet, use a drill
- larger than the rivet hole.
- same size as the hole.
- smaller than the rivet hole.
according to CAAIP it should be smaller than the shank of the rivet when removing rivet.
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
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.
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
If the operator varies the content of the maintenance schedule, what action must be taken?
- Amend the Maintenance Schedule first and then seek CAA approval.
- Await CAA approval before amending the Maintenance Schedule.
- Amend the Maintenance Schedule without further approval.
whenever manufacturer makes any changes in the publication it is the duty of operator to revise their maintenance schedule and apply for approval.Authority may take time to approve.so its first step is to amend and seek for approval rather than waiting for CAA approval before amending because in some cases it may be mandatory and needs to be done in very short period of time.
please explain those who agree to
Await CAA approval before amending the Maintenance Schedule
Springs are manufactured from
- high carbon alloy steel with high strength requirements.
- low carbon alloy steel with high strength requirements.
- high carbon alloy steel with low strength requirements.
i think in module 6 it literally said that the correct answer was "high carbon alloy steel with low strength requirements" am i wrong?Or did i get confused?
