ATSEP BASIC - All in one Quiz What type of surveillance is regarded Non-cooperative, independent surveillance? - PSR radar What surveillance technique is ADS-B? - Cooperative, dependent surveillance What is an example of Cooperative, Independent surveillance? - SSR radar How is an aircraft detected by the PSR? - By reflected electromagnetic energy transmitted from the radar What is radar clutter on an ATM radar? - Unwanted targets What is a limitation to the PSR radar? - No identification of received echoes What is meant by PRI? - Pulse repetition interval What is the purpose of the duplexer? - To alternately switch the antenna between receiving and transmitting What is the operating principle of the aircraft transponder? - To code a reply on the 1090MHz frequency in response to a SSR radar interrogation What is transmitted on a Mode C reply from a transponder? - Pressure altitude What is it called when replies from 2 aircraft overlap causing errors in extracting the included data? - Garbling What is a disadvantage of the classical SSR radar? - Garbling can occur if 2 aircraft are close in slant range and on the same bearing What is a feature of Mode S? - Selective interrogations to reduce FRUIT What is provided with Mode S enhanced surveillance? - Downlinked aircraft parameters What is a feature of the Monopulse SSR radar? - Improved azimuth resolution and fewer pulses needed to determine position ADS (automatic dependent surveillance) is a surveillance technique for use by ATS in which: - Aircraft automatically provide, via data link, data from on-board navigation systems What is a feature of ADS-B? - High update rate and simple, omnidirectional receivers Which airborne equipment supports the 1090ES messages? - The Mode S transponder What is the dominant ADS-B data link technology in Europe? - 1090 extended squitter What is the purpose of Mode S Short squitter? - ACAS/TCAS interrogations What is variation? - The difference between true and magnetic north What is meant by instrument flight rules? - Flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals What is the most common geodetic reference system with global coverage? - WGS 84 What is meant by "dead reckoning"? - Determining position based on known speed, course and elapsed time What is meant by "course" in relation to aircraft movement? - The direction over the ground the aircraft is moving What is considered an integrity risk in relation to navigational performance? - That undetected navigational system errors results in hazardously and misleading information to an aircraft On what frequency band is the DME operating on? - UHF What is an advantage with the NDB? - The low operating frequency allow reception beyond line of sight How does the VOR create the different radials? - By transmitting 2 signals with different phases What information does the pilot get from a NDB? - Direction only to the station What is a disadvantage of the NDB? - The signal is subject to interference and reflections What airborne equipment is required to make use of a VDF? - A VHF radio What principle is used in VOR bearing measurements? - Phase comparison What elements are required for a ILS?
