Aircraft Performance Aviation Lore
 

I'm doing a short presentation on Aircraft Performance and trying to throw in some comments on where did it all came from. I've got pretty good documenttation on where much of the TO Performance came from - Specifications from TWA for what turned out to be the DC-1.

I recall reading (I think in PPRUNE) about the 35' above the takeoff surface coming from ground effect being considered to be 1/2 the wingspan and the DC-1 had a wingspan of 70'. That was a great story until I read that the wingspan of a DC-1 was 95'.

Does anyone have information on this or a link to a thread on it.

Great thread from the true Performance Gurus of the industry.

Thanks for any suggestions or information.
