ATALIS Ready for ICAO NEW Flight Plan



Egis Avia is proud to announce that ATALIS now implements ICAO NEW FLIGHT PLAN, according to official and latest ICAO and EUROCONTROL specifications.

The key point of this implementation is clearly to be able to handle migration steps smoothly, taking into account the fact that the worldwide migration to INFPL may last several months, and may not be consistent for all systems and countries at the same time.


ATALIS can dynamically switch to all required transition phases, without any loss of data or technical task, at the relevant time as wished by each ANSP.

ATALIS smooth transition to ICAO New Flight Plan

 At the beginning of transition phase (PRESENT state), the system will accept only PRESENT FPL.


 Then, ATALIS will accept both FPL formats, received from any external system.


 ATALIS converts FPL format from NEW to PRESENT, using official CFMU/ICAO mapping rules, when required (COMPATIBLE state)


 During migration (MIXED state), ATALIS will allow users to work with both FPL format at the same time.


 At the end of transition phase (NEW state), the system will only accept and work with NEW FPL.


 All backward and forward compatibility are provided during these transition phases.



ATALIS implements the advanced ICAO requirement, requesting the systems to be able to send the right format to the right destination.
Shortly, it means that ATALIS will not send a NEW message to a destination known as not migrated, even for internally NEW Flight Plan.

To achieve that, ATALIS Aeronautical reference database, already extensively used for message analysis and MMI lists of values and helps, has been enhanced to add that particular INFPL information .

Based on this, the system creates two set of messages for the same flight, one in NEW for migrated destination, one in PRESENT for others.

ATALIS INFPL release can be delivered to ANSP, followed by an according assistance and support.
