The CAA has published an amended version of its Wake Turbulence Categorisation Database. The database should be used by ATC service providers in conjunction with the wake turbulence categories in Appendix B to the MATS Part 1 (CAP 493) to determine the required wake turbulence separation.
Version 2 of the database includes a new tab providing details on amendments made to the database. Note that, amongst other amendments, Version 2 introduces 3 new aircraft types, and revises the wake turbulence category of the A139 helicopter from UK LIGHT to SMALL. Version 2 of the database is effective on publication.
