ACCELERATE TO STOP and ZERO THRUST in the AFM?

[JimC]

My 1968 337C Handbook says accelerate-stop (0->85 mph->0) is 2450 ft. No idea why it dropped on later models that got heavier. I sent you the page from the POH; I can't include the single page here (it's oversize.)

The industry seems to be moving towards an accelerate stops distance computation by computing the takeoff ground roll with two engines plus the stopping distance, it doesn't matter two engines running or not. If you wish to be more conservative compute the two engine takeoff distance to 50' plus the landing distance from 50' and that becomes Balance Field Length. It assures you won't run off the runway in these older aircraft. No Guarantees! Wet runways add 50%. Snow add 100% and Ice covered runways don't go!

Accelerate Stop - don't go there as it is not published

It's a general rule for GA aircraft that says if you haven't reached 70% of your takeoff speed by the time you've reached 50% of the length of the runway, you should abort your takeoff.
