ATC has always been most cooperative in sorting out any confusion and will quickly intervene if a safety issue arises.
Why should they have to sort anything out at all? If we all spoke the same language then there would be nothing to sort out.
the overhead break at 250 kias that would be an issue at most civilian airports
And the reason for that would be????? Have you ever flown one bearcat88?? If everyone knows where everyone else is (ie hearing and speaking the same language) and are flying the appropriate altitudes then there is no conflict. Any ATC worth it's weight in salt should be able to handle an overhead break.
Back over to you
