Radio Navigation - Level 4(QUESTIONS &ANSWERS)

Document Content and Description Below

The purpose of mode S is: - ✔✔for data linking, ATC surveillance and reduced R/T communications and use by TCAS II. If a radar beam, at a frequency of 10.000 MHz, is radiated from a parabolic di ... sh of diameter 15 cm, the azimuth target discrimination angle is: - ✔✔14° In a primary radar system: - ✔✔all radio frequency energy is produced by the radar located at the radar site. A pilot wishes to obtain the magnetic bearing of his aircraft from a VDF station. Which of the following terms would he use: - ✔✔QDR A frequency of 295 KHz would be described as: - ✔✔LF. In order to have good sensitivity to water droplets in cumuli type clouds, the wavelength of an AWR should be: - ✔✔approximately 3 cm. When a maximum range and altitude is published for a VOR? - ✔✔The reception from this VOR is guaranteed free from harmful interference from other VORs when you are within this airspace. An SRA may be flown to: - ✔✔2.0 nm using QFE unless the pilot advises the controller the approach is to be flown on QNH. A ground radar transmitting at a PRF of 1200 pulses/second will have a maximum unambiguous range of approximately: - ✔✔67 NM. For a 3° ILS glidepath the approximate angles of lower and upper vertical coverage are: - ✔✔1.35° - 5.25° . Assuming sufficient transmission power, the maximum range of a ground radar with a pulse repetition frequency of 450 pulses per second is: (Given: velocity of light is 300 000 km/second) - ✔✔333 km. In an AWR with a 5 deg beamwidth, how do you orientate the scanner to receive returns from clouds at or above your level? - ✔✔2.5 deg uptilt An aircraft is flying a constant heading with 8° right drift and is making good a track parallel to the centre line of an airway but 5 nm off to the left of the centreline. The ADF reading of a NDB on the airway centreline 42 nm ahead of the aircraft is: - ✔✔015° Relative. [Show More]
