Investment Detail
The latest ROI calculation for the ASWON program was completed in May 2007 for the ASWON/ ASOS Pre-Planned Product Improvement (P3I) project. The Business Case Analysis Report (BCAR) calculated a Benefit/Cost (B/C) ratio of 9.5 for the work extending the ASOS weather system operational life. The primary sources of benefits were the Passenger Value of Time and Aircraft Operator Cost Savings. The ASWON/ ASOS P3I project was completed in 2012 and is expected to extend the ASOS life cycle beyond the 2020 goal.
