Question : 1 - 20 21 - 40

Question 1 - 5 of 20 (10 points each question)

1) In the base of a Direct reading compass are 4 magnets. The purpose of these is to: Report

Damp the movement.

Correct for coefficient A.

Correct for coefficients B and C.

2) When swinging a standby compass, errors on North are usually removed by Report

rotating the compass around its vertical axis

adjusting the compensator magnets

adjusting the azimuth card

3) During a compass swing Coefficient 'A' is calculated so that the compass can be adjused for: Report

Deviation errors on West and East.

Deviation errors on North and South.

Mechanical miss - alignment of the compass with the aircraft center-line.

4) When making correction adjustments on a Direct Reading compass you should always: Report

Use a tool made from a non - magnetic material.

Ensure that the aircraft is on a North heading.

Ensure that all electrical systems are switched off.

5) Compass swings are carried out to Report

minimise the errors in calibration of the aircraft compass system.

eliminate all the errors in calibration of the aircraft compass system.

ensure that the aircrafts compass system is accurate on N,S,E,W only.

6) When carrying out a compass swing it is important to ensure: Report

Only that the aircraft is fully fueled.

Only that the control locks are installed.

The aircraft is as close as possible to its normal level flying configuration.

7) When using a Datum/Landing compass to carry out a compass swing on the aircraft, how do you ensure the Datum/Landing compass is accurate ? Report

By checking its calibration date.

By observing a distant object and taking a reading and comparing that with the bearing on a chart.

Datum/Landing compasses are far more accurate than aircraft compass systems and therefore they are accurate.

8) When carrying out a compass swing with a Datum/Landing compass on a light aircraft it must be aligned with the compass on every sighting.This can be achieved by: Report

Lining up the Vertical Stabilizer with the center of the cockpit window in the sight.

Lining up the left wingtip with the anti collision light in the sight.

Either (a) and (b)

9) Compass Swing procedures for a Direct Reading compass for a Remote Reading compass are: Report

Different in that remote reading compass swings, must be carried out using an electronic test set.

Different in that a remote reading compass must be checked at intervals of 30 deg.

The same.

10) A Compass Deviation (Steer by) card: Report

Must be completed after a compass swing and stored away as a record of the compass swing and the compass accuracy.

Must be completed after a compass swing and attached to, or near the compass.

Is used to record the readings of the Datum compass as we carry out the compass swing. These values are then used to calculate coefficients A, B, C.

11) Remote Reading compasses are so named as they have: Report

Remote sensing units called flux valves.

They are mounted remotely in the cockpit.

They can be operated remotely.

12) Remote Reading Gyro - magnetic Compasses: Report

Use a directional gyro to stabilise the magnetic heading information from the flux valve.

Stabilise the gyro with information from the standby compass.

Stabilise the magnetic compass with information from the flux valve.

13) A Flux Valve can be described as a: Report

A wheel shaped device made of ferrous material with three spokes and the rim cut into three equal parts.

A fluid filled device, with a magnet suspended on a jewel pivot in the centre of the device.

A valve that opens and closes causing a magnetic flux to be generated.

14) In a fixed wing aircraft the Flux valves are typically located. Report

At the wingtips

In the avionics bay

In the HSI (Horizontal Situation Indicator)

15) A Compass Coupler, is designed to: Report

Determine the aircraft heading by measuring the output of the flux valve then precess the directional gyro to synchronies it with the aircraft heading.

Cross couple both number one and number two compass systems in the event of a failure of one system.

Connect the output of the directional gyro to the RMI (Radio Magnetic Indicator) and HIS (Horizontal Situation Indicator).

16) The two adjustment screws in the front of a direct reading compass are used to calibrate the compass. These screws achieve this by: Report

Moving the jewel pivot up and down causing the compass card to be deflected.

Moving the jewel pivot left and right causing the compass card to be deflected.

Moving two magnets under the compass and therefore causing the compass to be deflected.

17) Which two common cockpit instruments receive heading information signals from the flux valve/DG (remote) compass system? Report

R.M.I and H.S.I.

A.D.I. and V.S.I.

H.S.I. and A.D.I.

18) Correction charts are commonly used with Report

compasses

attitude indicators.

altimeters.

19) Flight Data Recorders are generally located in the Report

avionics compartment

cockpit

rear of the fuselage

20) Flight Data Recorders (FDR's) record Report

audible sounds in the cockpit

multiple aircraft parameters

the cause of aircraft crashes.
