Tops and bottoms/flex
Two numpty questions I'm afraid.
What are tops and bottoms (e.g. 'bottoms full and free' and 'my tops')? Probably a very quick answer to a silly question but I've just never used these terms first hand so far in my training. I could make assumptions but I'd rather ask, and know for sure.
Secondly, I've heard "N1's achieved" and "Flex achieved" during the take-off roll. Do they mean the same thing or is there a subtle difference?
Thanks, I think I've shown my naïvety quite enough now.
