In the examples you quoted and that I mention, even with more complex instruments reading sim data that you now mention (not from files!) then I still see absolutely no discernible difference in operation or indeed in execution in Air Manager - apart from a more confusing way to write the code - so I stand by what I say unless I have it on some real authority.
Oh, I fully understand the differences between synchronous and asynchronous by the way
