Va - what's it all about?
In my ATPL groundschool notes, I have Va as the design manoeuvre speed.
I can only think Va is nominated during design/certification stages to cover a set of arbitrary manoeuvres at the given speed.
After all, I'm sure it's more than possible for pilot induced structural failure below Va.
Can anyone expand on how Va is established?
