Re: Pratt & Whitney R-1830 performance chart
Franek,
I have the original 'Operators Handbook' (Not a copy) for the Pratt & Whitney Twin Wasp C4 R-1830 Engine which gives various charts on the engine performance. If you would like scans of the charts please PM me with your email address.
and in the next couple of days I'll send them on to you.
Regards
Peter.
