• Status of Canadian AMDAR Program Development

Development with First Air

• TAMDAR/ISAT/Internet proof-of-concept system on
  test B727 producing data to CMC
• Ground-based QA/QC of TAMDAR data conducted by
  Skytrac
• An AirDat 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

Typical daily coverage - test B727

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 CC 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-100s 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

AeroMechanical Services

• Alternative AMDAR system using AMS Automated
  Flight Information Reporting System (AFIRS) /
  Uptime installed on 3 Hawkair DHC-8 and 2
  Canadian North B737-200
• 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 B737-200s servicing
  the North display extremely high wind bias
  resulting from both the aircrafts navigational
  equipment and the way the aircraft are navigated
  in Northern Domestic Airspace. Solutions may not
  be economical

Development with Westjet

• WestJet now ready to join the Canadian AMDAR
  Program
• ACARS-based with SITA service
• Will be operating 54 B737-NG by end of 2005
• However 12-month delay expected in delivery of
  upgraded FDAMS/ACMS by Honeywell

8

• Monitoring of GLFE-TAMDAR at CMC

9

• 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
