AH already has a warning... it is called a stall horn.

You have to be smarter than the computer… and much of that is learned “smarts”.
Remember, in actuality there is no runway in AH that is long enough for a B29 to take off legitimately. All you can do is A> make sure you’re on as long of a runway as possible; B> make sure there is clear space at the end of a runway; C> make sure you used WEP and flaps UP while taking off. Go ahead and use auto pilot until the last possible moment then manually float the plane out of danger. KEEP FLAPS UP!!! Speed is life.
When you’re able use the longer runway on a large field that is elevated and has a drop off at the end of the runway. If you’re using 40,000lbs of ord, and full fuel, it is almost mandatory.
