1,2,4
Q4. Variation is defined as the angle between:
TN and MN.
Q5. An aircraft takes-off on a runway with an alignment of 045°. The isogonic line on the area chart indicates 0°. The compass deviation is 0°. On a take-off with zero wind, the northerly turning error:
is such that the compass will indicate a value noticeably below 045°.
Q6. If the CH = 220°, var. = E12, dev. = W2, what is the corresponding TH?
TH = 230°
Q7. In a steep turn, the northerly turning error on a magnetic compass on the northern hemisphere is:
equal to 180° on a 090° heading in a right turn.
Q8. In the Northern hemisphere, during deceleration following a landing in a Westerly direction, the magnetic compass will indicate :
an apparent turn to the South.
Q9. In the northern hemisphere, during deceleration following a landing in an Easterly direction, the magnetic compass will indicate :
an apparent turn to the South.
Q10. In the Northern Hemisphere, a magnetic compass will normally indicate a turn towards North if:
An aircraft is accelerated while on an east or west heading.
Q11. During deceleration following a landing in Northerly direction, the magnetic compass will indicate :
no apparent turn.
Q12. A pilot wishes to turn right on to a northerly heading with 20° bank at a latitude of 40° North. Using a direct reading compass, in order to achieve this he must stop the turn on to an approximate heading of :
330°
Q13. The compass heading can be derived from the magnetic heading by reference to a:
compass swinging curve
Q14. In the Northern Hemisphere, a magnetic compass will normally indicate a turn towards North if:
an aircraft is accelerated while on an east or west heading.
Q15. A pilot wishes to turn left on to a northerly heading with 10° bank at a latitude of 50° North. Using a direct reading compass, in order to achieve this he must stop the turn on an approximate heading of :
030°
Q16. Concerning magnetic compasses, deviation is:
The angular difference between magnetic North and compass North.
Q17. A remote indicating compass has usually less deviation error than a panel mounted compass because:
it is normally mounted in a part of the airplane where magnetic interference is minimal.
Q18. In the Southern hemisphere, during deceleration following a landing in an Easterly direction, the magnetic compass will indicate :
an apparent turn to the North.
Q19. The main reason for having the centre of gravity below the pivot point in a card-type magnetic compass is:
To compensate for the vertical magnetic component Z such that the magnet system is within approx. 2° of the true horizontal between 60° N and 40° S.
Q20. During deceleration following a landing in a Southerly direction, the magnetic compass will indicate :
no apparent turn.
Q21. Among the errors of a magnetic compass, are errors:
in North seeking, due to bank angle and magnetic heading
Q22. When turning onto a northerly heading the rose of a magnetic compass tends to “undershoot;” when turning onto a southerly heading it tends to “overshoot”: 1) these compass indications are less reliable in the northern hemisphere than in the southern hemisphere. 2) these compass oscillations following a lateral gust are not identical if the aircraft is heading north or south. 3) [truncated/omitted in text]. The combination of correct statements is:
2 and 3.
Q23. The quadrantal deviation of a magnetic compass is corrected by using :
soft iron pieces
Q24. The purpose of compass swinging is to determine the deviation of a magnetic compass :
on any heading
Q25. The purpose of a compass swing is to attempt to coincide the indications of:
compass north and magnetic north.
Q26. A pilot wishes to turn right on to a southerly heading with 20° bank at a latitude of 20° North. Using a direct reading compass, in order to achieve this he must stop the turn on an approximate heading of :
210°
Q27. In the vicinity of the magnetic North Pole the magnetic compass is useless because:
The horizontal component of the magnetic field is too weak.
Q28. Magnetic compass swinging is carried out to reduce as much as possible :
deviation.
Q29. What should be the indication on the magnetic compass when rolling into a standard rate turn to the right from a south heading in the Northern Hemisphere?
The compass will indicate a turn to the right, but at a faster rate than is actually occurring.
Q30. A pilot wishes to turn left on to a southerly heading with 20° bank at a latitude of 20° North. Using a direct reading compass, in order to achieve this he must stop the turn on an approximate heading of :
160°
Q31. The quadrantal deviation of the magnetic compass is due to the action of :
the soft iron pieces influenced by the geomagnetic field
