2916J.
729 J.
1458J.

Laurynas asking:

pls explain

Module 7. Maintenance practices

When drilling out a rivet, use a drill

larger than the rivet hole.
same size as the hole.
smaller than the rivet hole.

avionics asking:

according to CAAIP it should be smaller than the shank of the rivet when removing rivet.

Module 3. Electrical fundamentals

In a Wheatstone Bridge, the ammeter reads zero, and the variable resistor is adjusted to 5 ohms. Resistor P has a value of 10 ohms and Q has a value of 100 ohms. What is the value of the unknown resistor?

0.5 ohms.
5 ohms.
50 ohms.

pB1B2 asking:

how?

Module 1. Mathematics

Find the curved surface area of a cylinder diameter 20cm and length 10cm.

200 cm^2
628 cm^2
400 cm^2

Daivaras asking:

Please write your question here.

Module 3. Electrical fundamentals

In the circuit shown, impedance will be

5 ohms.
9 ohms.
7 ohms.

pB1B2 asking:

???

Module 3. Electrical fundamentals

To supply a 24volt output with a transformer with a 5:1 turns ratio, the input required is

4.8
24V.
120V.

pB1B2 asking:

help me pls

Module 8. Basic aerodynamics

The relationship between induced drag and airspeed is, induced drag is

directly proportional to the square of the airspeed.
directly proportional to airspeed alone.
inversely proportional to the square of the speed.

JD2016 asking:

Induced drag results from production of lift. Lift depends on airspeed squared, not 1 over airspeed squared.

Module 3. Electrical fundamentals

Total resistance in a parallel resistor circuit, of R1 and R2 is

RT = 1/R1 + 1/R2.
1/RT = (R1 * R2) Ã· (R1 + R2).
1/RT = 1/R1 + 1/R2.

pB1B2 asking:

i think the answer here is wrong! the true answer is RT = (R1 x R2) ÷ (R1 + R2)

Module 17. Propeller

If the tip of an electrical overshoe is torn

it may be cut back.
it may be classified as acceptable damage.
it must not be cut back.

ibrahimsoubra asking:

can someone explain this, i dont get what the question means by "cut back"

Module 9. Human factors

The blood/alcohol limit is

40 milligrams of alcohol per 100 millilitres of blood as the single universal limit applying equally to commercial aircrew, air traffic controllers and all maintenance engineers.
20 milligrams of alcohol per 100 millilitres of blood as the single uniform limit for commercial aircrew, air traffic controllers and licensed aircraft maintenance engineers alike.
20 milligrams of alcohol per 100 millilitres of blood for commercial aircrew, air traffic controllers and 80 milligrams of alcohol per 100 millilitres of blood for maintenance engineers.

zyle asking:

at my knowlegde second answer is correct? is it?

Module 13. Aircraft aerodynamics, structures and systems

When approaching the speed of s

pressure above the wing the wing in places
pressure above the wing equals the pressure below the wing
pressure above the wing can never exceed the pressure below the wing

Dusiata asking:

Can somebody place full question and answer? Should it be "speed of sound"?

Module 13. Aircraft aerodynamics, structures and systems

The ATC aerial has a polar diagram which is

directional
omni-dirrectional

Dusiata asking:

Directional? Maybe they have in mind radar antenna?

Module 13. Aircraft aerodynamics, structures and systems

With a bonding meter

the long lead is attached to the aircraft air frame and short lead to item
the short lead to the aircraft airframe and long lead to the item
it does not matter which lead goes where

Dusiata asking:

Could you show which lead is longer on most common T477W bonding meter? I hope there won't be such questions on real exam...
