ACCELERATE TO STOP and ZERO THRUST in the AFM?
 

Hello all.
Got a question for the forum.
Does anyone know what year the C337 AFM included "Accelerate-Stop" chart and "Zero Thrust" chart? I found that the 1971 C337 AFM has both. But since I own a 1965 C337 these item are NOT included. So if I can get this info from a AFM closer to my airplane I think my MEI/DPE will accept it.
Many Thanks.

It's not required for your plane. It was not in the certification.

I did my training in our 1967 337b in 1989 I found some training notes I made

Zero Thrust
Full forward Pitch
Adjust RPM with throttle 1950 Front & 2200 Rear

ACCELERATE TO STOP and ZERO THRUST in the AFM?
 

Thanks guys for the replies. Frank I saw the same in the 1971 AFM, so two year difference between our models isn't too bad. The main reason I'd like to know this info is my MEI asked me if I knew the "Zero thrust" settings? And for the Accelerate-to-stop info is basically in a "NOTE" in my AFM that states: "Accelerate from standing to 85 MPH and decelerate to a stop with heavy braking within 2300 feet at sea level". Although I'm sure that the book standard is NOT achievable with our old airplanes so with a safety margin of plus 50% or about 4500 feet is achievable--YES or NO?
Thanks again! BILLS

Frank or anyone. Any chance you could send me a copy of the "Zero Thrust" portion of your AFM? Appreciate it.

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.
