Question 1

Your aircraft is heading 075°M. The OBI is set to 025°. The VOR indications are 'TO' with the needle showing right deflection. Relative to the stations, you are situated in a quadrant defined by the radials:

Accepted Answer

205° and 295°

Answer

025° and 115°

Answer

295° and 025°

Answer

115° and 205°

Question 2

A secondary radar can provide up to 4096 different codes. These 4096 codes can be used in:

Accepted Answer

All modes

Answer

Mode S

Answer

Mode C only

Answer

Mode A only

Question 3

A radio beacon has an operational range of 10 NM. By what factor should the transmitter power be increased in order to achieve an operational range of 20 NM?

Accepted Answer

Four

Answer

Eight

Answer

Six

Answer

Two

Question 4

Which of the following statements about the accuracy that can be obtained with the LAAS (local area augmentation system) of the satellite navigation system NAVSTAR/GPS is correct?

Accepted Answer

The closer the receiver is to a LAAS ground reference station, the more accurate is the aircraft position fix.

Answer

A LAAS cannot correct for satellite timing and orbital position error.

Answer

The increase in accuracy of position fixes is independent of the aircraft position in relation to the LAAS ground reference station.

Answer

A LAAS corrects the position of the aircraft by relaying the information via a geo-stationary satellite.

Question 5

In a Satellite-Assisted Navigation system (GNSS/GPS) a position line is obtained by:

Accepted Answer

Timing the period that is taken for a satellite's transmission to reach the aircraft's receiver

Answer

The aircraft's receiver measuring the phase angle of the signal received from a satellite in a known position

Answer

The aircraft's receiver measuring the time difference between signals received from a minimum number of satellites

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 6

Which of the following is the ICAO allocated frequency band for ADF receivers?

Accepted Answer

190 - 1750 kHz

Answer

300 - 3000 kHz

Answer

255 - 455 kHz

Answer

200 - 2000 kHz

Question 7

What is the cross track deviation (XTK) indicated on an RNAV system?

Accepted Answer

The distance between the actual position and the great circle track between two active waypoints.

Answer

The distance between the air position and the planned track

Answer

The distance between the air position and the great circle track between two active waypoints.

Answer

The distance along a track between two waypoints

Question 8

What is the approximate angular coverage of reliable navigation information for a 3° ILS glide path out to a minimum distance of 10 NM?

Accepted Answer

0.7° above and below the glide path and 2.5° each side of the localiser centreline

Answer

0.45° above the horizontal to 1.75° above the glide path and 8° each side of the localiser centreline

Answer

1.35° above the horizontal to 5.25° above the horizontal and 8° each side of the localiser centreline

Answer

3° above and below the glide path and 10° each side of the localiser centreline

Question 9

Which one of the following is an advantages of a multi-sensor system using inputs from a global navigation satellite system (GNSS) and an inertial navigational system (INS)?

Accepted Answer

The GNSS can be used to update a drifting INS

Answer

The average position calculated from data provided by both systems increases overall accuracy

Answer

The activation of 'Selective Availability' can be recognised by the INS

Answer

The only advantage of coupling both systems is double redundancy

Question 10

Given: W/V (T) 230/20 KT, Var. 6E, TAS 80 KT What relative bearing from an NDB should be maintained in order to achieve an outbound course of 257°(M) from overhead the beacon?
