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