Data collection

• From 11 July 2011 0630UTC to 12 July 2011 0645 UTC, the ADS-B system saw 524 targets, including: 502 aircraft (429 entered Singapore FIR) 20 ground vehicles 2 test transponders

• For the analysis, we do not consider ground vehicles and test transponders

• In terms of movement, we see a total of 1,282 aircraft movements of which 996 entered the Singapore FIR
