ATSEP BASIC - All in one Quiz-correctly answered

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
