And again, without a precise description of the problem, it's impossible to say what the problem really is. Like which airplane is used, if you have a custom profile for it, which scenery, if you have a custom profile for the airport. Everything.
Please don't repeat "all airports and all aircrafts", it's just not possible. Maybe you meant "the few airports and the few aircraft I tried" but, without knowing all the details, it's impossible for us to help you.
