Question 1

In order to plot a bearing from a VOR station, a pilot needs to know the magnetic variation:

Accepted Answer

300

Answer

At the half-way point between the aircraft and the station

Answer

At the aircraft location

Answer

At both the VOR and aircraft

Question 2

In a 2D RNAV system you have entered the DME and VOR data for two waypoints. What do you use to work out the cross track errors when en-route from one to the other?

Accepted Answer

Use the automatically computed values on the CDI/HSI.

Answer

The pilot takes the VOR and DME information and computes it himself

Answer

The pilot is presented with VOR/DME information which must then be correlated to the pressure instruments to determine the effect of altitude

Answer

The four letter SELCAL code

Question 3

The Flight Management System (FMS) is organised in such a way that:

Accepted Answer

The navigation database is read only to the pilot.

Answer

The pilot is able to modify the navigation database in the FMC between two updates.

Answer

The navigation database of the FMC is valid for one year.

Answer

Timing the period that is taken for a transmission from the aircraft's transmitter/receiver to reach and return from a satellite in a known position

Question 4

In the NAVSTAR/GPS satellite navigation system, receiver clock error:

Accepted Answer

Can be minimised by synchronisation of the receiver clock with the satellite clocks

Answer

Is the biggest part of the total error

Answer

It cannot be corrected

Answer

Is corrected by using signals from four satellites

Question 5

If you are flying a back course ILS, you are flying a:

Accepted Answer

Non precision approach on the reciprocal runway of the precision approach runway

Answer

Precision approach on the precision approach runway

Answer

Precision approach on the reciprocal runway of the precision approach runway

Answer

Figure 2

Question 6

A typical frequency employed in Distance Measuring Equipment (DME) is:

Accepted Answer

SHF band and uses frequency modulation techniques

Answer

100 MHz

Answer

10 MHz

Answer

100 GHz

Question 7

The distance between a NAVSTAR/GPS satellite and receiver is:

Accepted Answer

Determined by the time taken for the signal to arrive from the satellite multiplied by the speed of light

Answer

Determined by the phase shift of the Pseudo Random Noise code multiplied by the speed of light

Answer

Calculated, using the WGS-84 reference system, from the known positions of the satellite and the receiver

Answer

4

Question 8

The reason why the measured distance between a NAVSTAR/GPS satellite navigation system satellite and a receiver is called a 'Pseudo-Range' is because the:

Accepted Answer

Calculated range includes receiver clock error

Answer

Measured distance is based on the Pseudo Random Noise code

Answer

Movement of satellite and receiver during the distance calculation is not taken into account

Answer

7500

Question 9

What airborne equipment, if any, is required to be fitted in order that a VDF let-down may be flown?

Accepted Answer

VHF radio

Answer

VOR

Answer

VOR/DME

Answer

None

Question 10

Factors liable to affect most NDB/ADF system performance and reliability include:

Accepted Answer

Static interference - night effect - absence of failure warning system

Answer

Coastal refraction - lane slip - mountain effect

Answer

Height error - station interference - mountain effect

Answer

Static interference - station interference - latitude error
