Radio Navigation - ATPL - Airline Transport Pilot license

Test 10 domande Radio Navigation, tempo libero

1 - Airborne weather radars are generally based on the use of: Secondary radar in the SHF band Primary radar in the UHF band Secondary radar in the VHF band C/A- and P

2 - A pilot flying an aircraft at FL 80, tunes in a VOR which has an elevation of 313 m. Given ISA conditions, what is the maximum theoretical distance at which a pilot might expect to receive the VOR signals? 180 NM 151 NM 120 NM 160°

3 - Which of the following is an ILS localiser frequency? 109.15 MHz 112.10 MHz 110.20 MHz Phase difference between emitted wave and reflected wave

4 - Which of the figures depicts an Electronic Flight Instrument System (EFIS) display in Expanded (EXP) VOR/ILS mode with an VOR frequency selected?

Figure 4 Figure 1 Figure 6 Figure 5

5 - In a Satellite-Assisted Navigation System (GNSS/GPS), a fix is obtained by: Measuring the time taken for a minimum number of satellites' transmissions, in known positions, to reach the aircraft's receiver Measuring the pulse lengths of signals received from a minimum number of satellites received in a specific sequential order Measuring the time taken for an aircraft's transmissions to travel to a number of satellites, in known positions, and return to the aircraft's receiver Inhibit unwanted ground returns

6 - The different segments of the satellite navigation system NAVSTAR/GPS are the: Control, space and user Atomic clock, power supply and transponder Antenna, the receiver and the central control unit (CDU) L2-coarse acquisition (C/A)

7 - In which frequency band do Satellite-Assisted Navigation systems (GNSS/GPS) provide position information that is available to civil aircraft? UHF VHF EHF Continuous automatic position reporting using Global Positioning System (GPS) satellites and collision avoidance using TCAS II

8 - In which frequency band do most airborne weather radars operate? UHF SHF VHF 550 FT/MIN

9 - Which one of the following inputs to an Area Navigation System (R-NAV) comes from an external, not on-board, system? Inertial Navigation System (INS) position Magnetic heading Pressure altitude VOR/DME radial/distance

10 - An aircraft is on radial 120 with a magnetic heading of 300°, the track selector (OBS) reads:330. The indications on the Course Deviation Indicator (CDI) are 'fly': Left with 'TO' showing Left with 'FROM' showing Right with 'FROM' showing 180°
