2018 Provisional ATC Developments
The following new class structures were voted on by EphMRA/PBIRG in May/June 2017 and agreed in principle. These structures will now be used in the next part of the development process which is the detailed refinement of the rules. Please note that these new class structures are provisional at this time.
