FAA Delays Domestic Use of ICAO Flight Plan Again


posted in

International Flight Plan Update
Notice Number: NOTC7186

The FAA held a two day meeting on May 23-24 with Nav Canada and vendors (Harris Corporation, CSRA and Leidos) to review testing results between all operating systems for implementation of the new FAA requirement for International Flight Plan (ICAO) format for all civil flights filed with Flight Service.*

To ensure a safe and seamless transition with full interoperability, the FAA has decided to delay implementation until the Fall of 2017. The additional time will allow all service providers to address required changes identified in testing and integrate enhancements to the international format, while avoiding system changes during the busy summer flying season.  The FAA will provide a 30-day advance notice to the public when a final date is selected later this year.
