What is windshear
Does anybody have a definition of windshear. We often report to ATC windshear on approach when really it was probably just turbulence. Different authorities define it differently - FAA,CASA,CAD etc.
But what is it. 15 knots or greater sounds familiar but over what period of time.
any thoughts.
And while i am in a posing question mood, what is freezing fog.
Does temp below fzg combined with fog constitute fzg fog. A meteorologist would say no, it depends on things like the moisture content of the air and the liklyhood of super cooled water droplets.
But from an aviation point of view (A330 ground ice shedding proc) when do we consider fzg fog?
