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.When using the ILS, a false glidepath is: - ✔✔always found above the real glidepath. When data are published for an hyperbolic navigation system, they are valid: - ✔✔for users at sea level. What is the range of long range ground radar? - ✔✔300nm The sky search carried out by a GNSS receiver: - ✔✔is done when the receiver position is in error. The SHF band has been selected for Airfield Surface Movement Indicator (ASMI) radars in preference to the EHF band because: - ✔✔the attenuation caused by precipitation is greater in the EHF band and reduces the radars effective range and usefulness. What are the primary navigation inputs used by RNAV system? - ✔✔Nav Aids, INS, FMC database. The ICAO designation for VOR is: - ✔✔A9W When considering the propagation of ADF transmissions night effect is most pronounced: - ✔✔at dusk and dawn. Using a 5 dot CDI, how many dots would show for an aircraft on the edge of an airway at 100 nm from the VOR beacon? [Show More]
