Radio Navigation - ATPL - Airline Transport Pilot Licence

Test 10 domande Radio Navigation, tempo libero

1 - According to ICAO Annex 10, in which frequency band(s) does a locator normally transmit? MF/HF HF LF/MF HF/VHF

2 - How does the Electronic Flight Instrument System display of a B737-400 respond to the failure of a VHF navigation (VOR) receiver? The pointer rotates around the display and a VOR 1 or 2 failure warning bar appears It removes the associated magenta deviation bar and/or pointer from the display The pointer flashes and a VOR 1 or 2 failure warning bar appears The deviation bar and/or pointer change colour to red and flash intermittently

3 - In relation to the satellite navigation system NAVSTAR/GPS, the term 'inclination' denotes the angle between the: Horizontal plane at the location of the receiver and the direct line to a satellite Orbital plane and the equatorial plane Horizontal plane at the location of the receiver and the orbital plane of a satellite It varies, depending on the time and observer's location

4 - The two signals transmitted by a conventional VOR ground station are 90° out of phase on magnetic: South West East Slant range.

5 - In relation to the NAVSTAR/GPS satellite navigation system, 'Search the Sky' is a: Procedure performed by the receiver to recognise new satellites becoming operational Continuous process by the ground segment to monitor the GPS satellites Continuous procedure performed by the receiver that searches the sky for satellites rising above the horizon Geometric height above ground

6 - In relation to Area Navigation Systems (RNAV), which of the following is an Air Data input? VOR/DME radial/distance Inertial Navigation System (INS) position Doppler drift 760

7 - A ground radar transmitting at a PRF of 1200 pulses/second will have a maximum unambiguous range of approximately: 135 NM 67 NM 27 NM 400 FT/MIN

8 - 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)

9 - In relation to the NAVSTAR/GPS satellite navigation system, what is involved in the differential technique (D-GPS)? Receivers from various manufacturers are operated in parallel to reduce the characteristic receiver noise error The difference between signals transmitted on the L1 and L2 frequencies are processed by the receiver to determine an error correction Signals from satellites are received by 2 different antennas which are located a fixed distance apart. This enables a suitable receiver on the aircraft to recognise and correct for multipath errors Monitor the orbital planes of the satellites

10 - Which component of the Electronic Flight Instrument System generates the visual displays on the EADI and EHSI? Flight Control Computer Flight Management Computer Navigation database 17 NM
