Question 2

An aircraft is situated at 30°N - 005°E with a magnetic variation of 10°W. A VOR is located at 30°N - 013°E with a magnetic variation of 15°W. The aircraft is situated on the VOR radial:

Accepted Answer

285°

Answer

101°

Answer

281°

Answer

256°

Question 3

The DME (Distance Measuring Equipment) operates within the following frequencies:

Accepted Answer

962 to 1213 MHz

Answer

329 to 335 MHz

Answer

108 to 118 MHz

Answer

962 to 1213 kHz.

Question 4

How does a receiver of the NAVSTAR/GPS satellite navigation system determine the elevation and azimuth data of a satellite relative to the location of the antenna?

Accepted Answer

It calculates it by using Almanac data transmitted by the satellites

Answer

The data is stored in the receiver together with the Pseudo Random Noise (PRN) code

Answer

The data is determined by the satellite and transmitted together with the navigation message

Answer

The data is based on the direction to the satellite determined at the location of the antenna

Question 5

Airborne weather radars are generally based on the use of:

Accepted Answer

Primary radar in the SHF band

Answer

Secondary radar in the SHF band

Answer

Primary radar in the UHF band

Answer

Secondary radar in the VHF band

Question 6

How does a NAVSTAR/GPS satellite navigation system receiver recognise which of the received signals belongs to which satellite?

Accepted Answer

Each satellite transmits its signal, on common frequencies, with an individual Pseudo Random Noise code

Answer

Each satellite transmits its signal on a separate frequency

Answer

The receiver detects the direction from which the signals are received and compares this information with the calculated positions of the satellites

Answer

The Doppler shift is unique to each satellite

Question 7

The two main design functions of Secondary Surveillance Radar (SSR) Mode S are:

Accepted Answer

Air to ground and ground to air data link communications and improved ATC aircraft surveillance capability

Answer

Collision avoidance using TCAS II and improved long range (HF) communication capability.

Answer

The elimination of ground to air communications and the introduction of automatic separation between aircraft using TCAS II

Answer

Continuous automatic position reporting using Global Positioning System (GPS) satellites and collision avoidance using TCAS II

Answer

272°(M)

Answer

300°(M)

Answer

280°(M)
