ATSEP BASIC - All in one Quizzes And Answers

ATSEP BASIC - All in one Quizzes And Answers 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? LOC, GP and markers or DME What information does the pilot get from the glide path? The correct vertical decent profile Of what use, if any, can a military TACAN be used by civilian aircraft? Civilian aircraft can use the DME part What is EGNOS? European satellite augmentation system for GPS/Galileo What navigation system can operate without external sources? INS What airborne augmentation technique uses additional satellites to determine the integrity of the GPS before it is used for navigation? RAIM (?) What is the major difference between RNAV and RNP? RNP requires on-board performance monitoring and alerting What time system is used in aviation? UTC time What is one of the key tasks of an ATSEP? Performing maintenance on CNS/ATM systems and equipment
