Thanks for the suggestion. I have a few friends who are airline pilots or just have an ATPL. I'll ask them as well and see what they say.
As mentioned before, I don't have the luxury of time of going and visiting the end users even if I ever get access to speak to the people I need to speak to - i.e the guys who do the maintenance or maybe the pilots. That's why I am using the forum as the next best thing, if not better.
