This page records changes made to the Black/Grey list since the 23rd May 2019 white list. It is maintained for information.

26th Mar 2020:

It was decided to add Embraer aircraft with RIU-4010 equipment to the list of avionics with performance concerns as they are observed to have a high PA rate, but the data is only available for aircraft on the SITA network and there is insufficient data to meet the ' 250 hours sample size' criteria.


16th Mar 2020:

It was decided to make BCS1 and BCS3 aircraft types (Airbus A220) with Rockwell Collins RIU-4010 with Data Link Communications Application (DCLA) version 810-0315-100 and Integrated Modular Avionics (IMA) version 810-0311-2B0005 eligible again for the Logon List as their recent performance seems acceptable. Their performance will be monitored.

4th Mar 2020:

It was decided to allow aircraft with the Thales EVR-750 (L22 version) and 'Amendment J' to join the Logon List. Amendment 'J' is a optimised configuration of the radio which Thales believe will perform better. Their performance will be monitored.

17th Oct 2019:

It was decided to add the Thales EVR-750 (L22 version) to the Black list, since it is observed to perform poorly on both the SITA and ARINC network and there is sufficient data to meet the defined criteria for black listing.

31st July 2019:

It has been decided to add the Thales EVR-750 (L22 version) to the Grey list, since it is observed to perform poorly on the SITA network. It does however perform relatively well on the ARINC network so the issue may not be an issue with the avionics but rather a combination of the avionics and the SITA network.

27th June 2019:

It was decided to black list B748 aircraft with RC 2100 VDRs and CMU900 CMUs. These aircraft are observed to have a high PA rate, despite the avoinics performing satisfactorily in other configurations. The poor performance is observed across different operators and different ANSPs.

23rd May 2019:

Following feedback from Rockwell Collins and some consequent analysis it been decided to change the Black listing of aircraft with RIU-4010 equipment from all aircraft with RIU-4010 installed to be just aircraft types BCS1 and BCS3 with an RIU-4010 and Data Link Communications Application (DCLA) version 810-0315-100 and Integrated Modular Avionics (IMA) version 810-0311-2B0005.

10th May 2019:

It was decided to remove the CMU900 before version ending -505 from the Black list. It had originally been included because the -505 version was identified as 'best-in-class' in the ELSA study, but in-service performance data shows no significant difference between the -505 version and earlier versions.

15th May 2019:

Following feedback from Rockwell Collins and some consequent analysis it been decided to change the Black listing of aircraft with RIU-4010 equipment from all aircraft with RIU-4010 installed to be just aircraft types BCS1 and BCS3 with an RIU-4010 and Data Link Communications Application (DCLA) version 810-0315-100 and Integrated Modular Avionics (IMA) version 810-0311-2B0005. Not all aircraft with an RIU-xxxx installed will have the DCLA and IMA installed, but for those that do we require new white list applicants to advise which version of each is installed on their aircraft - this is to help monitor the performance of the different configurations and provide feedback to the manufacturer.

June 2017:

It was decided to remove aircraft fitted with Garmin avionics from the 2nd June 2017 white list as they had been observed to suffer a higher than average PA rate. Garmin have subsequently stated that they believe aircraft fitted with Garmin Integrated Avionics version 7.72.x. or later should perform better and so aircraft fitted with this version are now eligible for the white list. Their performance will be monitored.

June 2016:

Version CSB8.3 of the Airbus ATSU is known to significantly reduce the number of provider aborts suffered. So in June 2016 the ANSPs decided that Airbus aircraft with an ATSU older than CSB8.3 would no longer be eligible to be added to the white list and also that aircraft already on the white list should be updated to CSB 8.3. A deadline for the update was initially set for the Sep 15th 2016 white list, however at the review of the September 2016 white list the ANSPs decided to extend the deadline for updates to the Feb 2017 white list (cut-off date for applications/ updates is the 11th Jan 2017) in recognition that some operators have experienced genuine difficulties meeting the date.
