Hi Tony,
Which model Ercoupe and with which engine?
For the 65 and 75hp C Models you pretty much have to work from data
given in the Ercoupe Instruction Manual and mark up a 415-D Manual.
The latter figures are derived at a gross weight of 1400 lbs., so are
conservative at 1360 (Light Sport STC) or 1260 lbs. (415-C gross).
Since it is relatively rare to have to land or take off over a 50'
obstacle these days, you may want to know minimum landing ground roll
and minimum take-off run. The "bottom line" is that you have to work
out a way of measuring that which you and your plane can accomplish.
Some of Fred Weick's papers show a "minimum take-off run" of 728' for a
415-C with a wood Sensenich prop (performance corrected to standard day
conditions) at 1400 lbs. and 75hp. I seem to recall that factory test
pilots could land and stop without damage on a paved surface in about
300', but that may have been at 1260 lbs. gross.
Regards,
William R. Bayne

Can anyone tell me how I can do a performance chart for take off's and
landing's in a Ercoupe? What information do I need and where can I get
it. Any help would be great.
Thanks You,
Tony
