I wouldn't worry about it at all. If you are, on an E145, I've seen the cockpit wide open before and after the flight on almost every flight - ask the FA if you can ask the pilots a Q and ask!
This is what I would do. Or if the pilots are hanging around after the flight, ask them. Whenever I ask a pilot a vaguely technical question I always get a friendly reply.
