I’ve been looking through the forums and haven’t found a direct answer.
Apparently no word has been said about removing this restriction since 2016. As others have stated years ago, this was meant to be a temporary rule. Again, I’m not 100% sure if this is still in effect but I would like to know plans for it. Thanks.
(If you didn’t read the title, I’m referring to the restriction of 550GS below FL400).
