Status of Canadian AMDAR Program Development 24 -25 August 2005 EC GLFE-TAMDAR Presentation 2

Development with First Air • TAMDAR/ISAT/Internet proof-of-concept system on test B 727 producing data to CMC • Ground-based QA/QC of TAMDAR data conducted by Skytrac • An Air. Dat engineer to calibrate TAMDAR before CMC evaluate quality of data • If test is positive plan is to deploy 7 more aircraft by 31 March 2006, and 7 remaining aircraft by 31 March 2007, each to be calibrated and tested before becoming operational 24 -25 August 2005 EC GLFE-TAMDAR Presentation 3

Typical daily coverage - test B 727 24 -25 August 2005 EC GLFE-TAMDAR Presentation 4

Development with AC Jazz • Jazz contributing about 25, 000 daily AMDAR observations of wind and temperature from a fleet of 25 CRJ-200 and 32 upgraded DHC-8 -100 and -300 aircraft to 67 destinations in Canada and the United States (4 August 2005) • Sabre C&C not expected to work fully before October 2005 • DHC-8 temperature data quality depends on phase of flight. Is believed to be due to T smoothing algorithm. Next upgrade opportunity by Universal Avionics is August 2006 • 25 Air Canada CRJ-100 s and 8 CRJ-200 from Independence Air to go to Jazz • Jazz acquiring 15 brand new CRJ-705 by 31 December 2005 with an option for 8 more. Rockwell Collins to extend AMDAR with access to roll and pitch angles to the CRJ-705 • By mid-May 2006, Jazz to operate 68 DHC-8 and 73 CRJ aircraft, all AMDAR-capable 24 -25 August 2005 EC GLFE-TAMDAR Presentation 5

Aero. Mechanical Services • Alternative AMDAR system using AMS’ Automated Flight Information Reporting System (AFIRS) / Uptime installed on 3 Hawkair DHC-8 and 2 Canadian North B 737 -200 • AMS deployed Harco temperature probe on the DHC-8 and CMC receiving data only from 1 of the 3 DHC-8. Not enough data collected yet to evaluate the quality of T • The 2 equipped Canadian North B 737 -200 s servicing the North display extremely high wind bias resulting from both the aircraft’s navigational equipment and the way the aircraft are navigated in Northern Domestic Airspace. Solutions may not be economical 24 -25 August 2005 EC GLFE-TAMDAR Presentation 6

Development with Westjet • West. Jet now ready to join the Canadian AMDAR Program • ACARS-based with SITA service • Will be operating 54 B 737 -NG by end of 2005 • However 12 -month delay expected in delivery of upgraded FDAMS/ACMS by Honeywell 24 -25 August 2005 EC GLFE-TAMDAR Presentation 7

Monitoring of GLFE-TAMDAR at CMC 24 -25 August 2005 EC GLFE-TAMDAR Presentation 8

• TAMDAR wind and temperature • Monthly mean values of observation minus first guess • Observations for all monitoring period (December 2004 - July 2005) • Slight deterioration of wind data from April to July 24 -25 August 2005 EC GLFE-TAMDAR Presentation 9
