1 - An aircraft is flying a 3° glidepath and experiences a reduction in groundspeed from 150 kt at the outer marker to 120 kt over the threshold. The effect of this change in groundspeed on the aircraft's rate of descent will be a decrease of approximately: 50 FT/MIN 250 FT/MIN 100 FT/MIN 150 FT/MIN

2 - Which one of the following correctly lists the major ground based components of a Microwave Landing System (MLS)? Separate azimuth and elevation transmitters, outer and middle marker beacons Separate azimuth and elevation transmitters, DME facility Combined azimuth and elevation transmitter, outer and inner marker beacons 140°

3 - The receiver aerial for a NAVSTAR/GPS system should be mounted: In the vicinity of the receiver to avoid long transmission lines Inside the tail fin to minimise the influence of reflections from the wing and fuselage Under the fuselage in order to receive correction data transmitted by D-GPS stations Only the 1575 MHz carrier wave and one code

4 - A weather radar, set to the 100 NM scale, shows a squall at 50 NM.By changing the scale to 50 NM, the return on the radar screen should: Decrease in area but not change in position on the screen Increase in area and appear nearer to the bottom of the screen Decrease in area and move to the top of the screen Increase in area and move to the top of the screen

5 - Which of these markers has the highest audible frequency? Inner Airways Middle Outer

6 - Which one of the following lists information given by a basic VOR / DME-based Area Navigation System? Crosstrack distance alongtrack distance angular course deviation 2500 MHz

7 - ILS is subject to false glide paths resulting from: Spurious signals reflected by nearby obstacles Multiple lobes of radiation patterns in the vertical plane Ground returns ahead of the antennas Back-scattering of antennas

8 - What is the maximum number of usable Secondary Surveillance Radar (SSR) transponder codes in Mode A? 3600 1000 4096 Frequency

9 - The influence of the ionosphere on the accuracy of the satellite navigation system NAVSTAR/GPS is: Minimised by computing the average of all signals Only significant if the satellites are located at a small elevation angle above the horizon Minimised by the receiver using a model of the atmosphere and comparing signals transmitted by the satellites Detect the larger water droplets

10 - The operating principle of a DME is the measurement of the: Frequency change between the emitted wave and reflected wave Frequency of the reflected wave Time between the transmission and reception of radio pulses 190 NM
