Flight Plan Changes

ICAO Flight Plan and ATS Message Changes effective 15 Nov 2012

ICAO have announced changes to the ICAO model flight plan form and ATS Messages in Amendment 1 to 15th Edition of PANS ATM Doc 4444  which will become applicable 15 Nov 2012.

The nature and scope of the amendment is to update the ICAO model flight plan form in order to meet the needs of aircraft with advanced capabilities and the evolving requirements of automated air traffic management (ATM) systems.

Changes are required to ATC flight data processing systems that check and accept flight plans and related messages, use flight plan data in displays for controller reference, use data in ATC automation and affect information that is communicated between ATC units as the flight progresses.

The Amendment contains a number of significant changes involving the length and content of Flight Plan Items.

Summary of Changes

  2. Item 10a –Radio Communication, Navigation and Approach aid Equipment and Capabilities
