1 - According to ICAO 8168, what is regarded as the maximum safe deviation below the glide path during ILS approach? Three quarter scale deflection. One quarter scale deflection. Full scale deflection. Half scale deflection.

2 - Which of the following equipments uses primary radar principles? Distance Measuring Equipment (DME) Secondary Surveillance Radar (SSR) Global Positioning System (GPS) Airborne weather radar (AWR)

3 - Regarding the DME system, which one of the following statements is true? The transponder reply carrier frequency differs by 63 MHz from that of the interrogation signal. When passing overhead the DME station the DME will indicate 0. The DME measures the phase difference between the reference and variable phase signals to calculate the distance. The four letter SELCAL code

4 - What is the cross track deviation (XTK) indicated on an RNAV system? The distance between the actual position and the great circle track between two active waypoints. The distance between the air position and the planned track The distance between the air position and the great circle track between two active waypoints. The transmitter moves toward the receiver

5 - The ISO-ECHO facility of an airborne weather radar is provided in order to: Give an indication of cloud tops Detect areas of possible severe turbulence in cloud Extend the mapping range 666 km

6 - Basic RNAV requires a track-keeping accuracy of: +/- 3NM or better for 90% of the flight time +/- 5NM or better for 95% of the flight time +/- 5NM or better throughout the flight 1090 +/- 0.3 MHz

7 - Instrument Landing Systems (ILS) Glide Paths provide azimuth coverage (i) ..... ° each side ofthe localiser centre-line to a distance of (ii) .... NM minimum from the threshold. (i) 8 (ii) 10 (i) 5 (ii) 8 (i) 35 (ii) 25 550 FT/MIN

8 - In relation to radar systems that use pulse technology, the term 'Pulse Recurrence Rate (PRR)' signifies the: The number of cycles per second Delay after which the process re-starts Ratio of pulse period to pulse width UHF

9 - What type of satellite navigation system NAVSTAR/GPS receiver is most suitable for use on board an aircraft? Multiplex Sequential Any hand held type Multichannel

10 - Which facility associated with the ILS may be identified by a two-letter identification group? Locator. Glide path. Outer marker. "Request QDR".
