ATSEP BASIC EXAM
ATSEP BASIC EXAM QUESTIONS AND ANSWERS
GRADED A+ LATEST UPDATE.
What type of surveillance is regarded non-cooperative,
independent surveillance? ANS >> PSR radar
What surveillance technique is ADS-B? ANS >> Cooperative,
dependent surveillance
What is an example of Cooperative, Independent surveillance?
ANS >> SSR radar
How is an aircraft detected by the PSR? ANS >> By reflected
electromagnetic energy transmitted from the radar
,ATSEP BASIC EXAM
What is radar clutter on an ATM radar? ANS >> Unwanted
targets
What is a limitation to the PSR radar? ANS >> No identification
of received echoes
What is meant by PRI? ANS >> Pulse repetition interval
What is the purpose of the duplexer? ANS >> To alternately
switch the antenna between receiving and transmitting
What is the operating principle of the aircraft transponder?
ANS >> 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?
ANS >> Pressure altitude
What is it called when replies from 2 aircraft overlap causing
errors in extracting the included data? ANS >> Garbling
, ATSEP BASIC EXAM
What is a disadvantage of the classical SSR radar? ANS >>
Garbling can occur if 2 aircraft are close in slant range and on
the same bearing
What is a feature of Mode S? ANS >> Selective interrogations
to reduce FRUIT
What is provided with Mode S enhanced surveillance? ANS >>
Downlinked aircraft parameters
What is a feature of the Monopoles SSR radar? ANS >>
Improved azimuth resolution and fewer pulses needed to
determine position
ADS (automatic dependent surveillance) is a surveillance
technique for use by ATS in which: ANS >> Aircraft
automatically provide, via data link, data from on-board
navigation systems
What is a feature of ADS-B? ANS >> High update rate and
simple, omnidirectional receivers
