Yes, given that (possibly) worst case scenario it would be problematic. Generally you're not re-making "Blue Thunder" in combat helicopters though :)
Neither would such a low frame-rate of 14 fps be practical with Track-IR either. But in general it's adequate. 15 is better, 20 great, 25+ and you're laughing. :lol:
Pilots wouldn't perform such crazy manuvers when visual feedback was so poor, equate low FPS with thick fog. You fly in 'response' in a helo rather than in 'command', meaning your environment dictates your actions much more so than open skies. That applies to physical environments and simulated feedback I think.
14 fps is far from ideal, I'm just stating that it's the lowest practical rate for helo flight in my experience, of course situations will vary that's a given. Personally I can't maintain a manual hover without one external fixed reference point and a min FPS of 20 (even then it gets messy). Not to mention the powered descents into the ground I make when lots of dust gets kicked up and the frame rate drops to a level where I don't realise it's happening until it's pancake time.
