For the moment, ATSIN 8 is a UK difference, to take account of the fact that states outside the UK refuse to believe that level busts are a safety issue.. .. .ICAO phraseology is all very well, but it's ICAO who gave us different languages, the Streamline fatality at CDG being one consequence (RIP).. .. .ICAO also offer us 'Holding positions', an accident waiting to happen.. .. .There is no point standardising with that which is unsafe. At least, we should drop the desire to be standard ICAO, and should pursue the elimination of all that makes standard ICAO so risky, before re-joining the ICAO process.. .. .It's no joke - lives depend on this.
