Projects determined to be eligible under the AIP are programmed by the FAA with input from state agencies into a "Capital Improvement Plan" commonly referred to as the CIP. The CIP is dynamic in that it often changes depending on several factors, including, but not limited to, the availability of funds, sponsor priorities, and readiness of the project sponsor. Given this uncertainty, it is important to limit the "out year" programming in order to maintain the integrity of the plan, and for this reason, the CIP is limited to 5 years.
The FAA Regional Office, with input from the Sponsor and the MassDOT Aeronautics Division, develops the CIP for Primary, Reliever and General Aviation Airports. Programming of discretionary funds is based on a priority system whereby airports compete against each other on a national basis.
