Ah, no chance of it being relevant to me then - thanks for clarifying! No way I would have been able to figure it out on my own. Just for future reference, is that timescale published on the EASA website somewhere? I can see mention of 'Q2 2018' as the point for the 'Decision' milestone, but cannot find anything to suggest why it would be the end of 2018 that such a change would actually take effect.
