1 - The BFO selector on an ADF receiver is used to: Hear the IDENT of some NDB stations radiating a continuous wave signal Find the loop 'null' position Hear the IDENT and must always be switched ON The GNSS can be used to update the FMS position from a drifting IRS.

2 - Which of the following is one of the functions of the Computer in a basic RNAV system? It transfers the information given by a VOR/DME station into tracking and distance indications to any chosen Phantom Station/waypoint It calculates cross track information for NDB approaches It automatically selects the two strongest transmitters for the Area-Nav-Mode and continues working by memory in case one of the two necessary station goes off the air VOR/DME Area Navigation computer is receiving neither radial nor distance data information from VOR/DME stations.

3 - The amplitude modulation and the colour of an outer marker (OM) is: 3000 Hz, blue 400 Hz, blue 400 Hz, amber DME callsign was not transmitted, the distance information is sufficient proof of correct operation

4 - Which of the following data, in addition to the Pseudo Random Noise (PRN) code, forms part of the so called 'Navigation Message' transmitted by NAVSTAR/GPS satellites? Time Data to impair the accuracy of the position fix Almanac data 6

5 - One of the tasks of the space segment of the satellite navigation system NAVSTAR/GPS is to: Transmit signals to suitable receivers and to monitor the orbital planes autonomously Compute the user position from the received user messages and to transmit the computed position back to the user segment Transmit signals which can be used, by suitable receivers, to determine time, position and velocity Monitor the satellites' orbits and status

6 - What approximate rate of descent is required in order to maintain a 3° glidepath at a groundspeed of 90 kt? 450 FT/MIN 700 FT/MIN 600 FT/MIN Stop the loop rotation

7 - Under CS-25 colour code rules features displayed in cyan/blue, on an Electronic Flight Instrument Systems (EFIS), indicate: Engaged modes The flight director bar(s) The sky Flight envelope and system limits

8 - What is the colour sequence when passing over an Outer, Middle and Inner Marker beacon? Amber - white - green Blue - amber - white Blue - green - white White - amber - blue

9 - Which of the following statements concerning the variable, or directional, signal of a conventional VOR is correct? The transmitter changes the frequency of the variable signal by 30 Hz either side of the allocated frequency each time it rotates The transmitter varies the amplitude of the variable signal by 30 Hz each time it rotates The receiver adds 30 Hz to the variable signal before combining it with the reference signal The rotation of the variable signal at a rate of 30 times per second gives it the characteristics of a 30 Hz amplitude modulation

10 - 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
