Just for the GA aircraft and a few really well simmed A/C, P-charts would be nice, to calculate T/O distance etc. Is there anyway to get them online?

Hey Connor. I'd be interested too, some of the payware stuff does include this sort of detail but you have to wonder just how closely it matches either the real world or what they've modelled.

GA , unless badly maintained act as close as possible and compared in FSX , the best and most honest answer is to fly a regular FS from your or well known airport or field , really get to understand what all areas from its entirety then try it out for real , you will be surprised how close it is .

Do a google of the aircraft your interested in, you'd be surprised at how much info is online for free.
You can buy flight manuals and performance info for everything but you might just find the info your looking for with a patient search.

I often Google the aircraft type and add 'pilots operating handbook' or 'flight manual' you can often discover some good information. Some of the more friendly GA manufacturers actually have their handbooks and/or performance data on their websites and other have responded to a politely phrased e-mail.

If you have a nearby flying club, pay them a visit and talk to the pilots there.

Whenever I do a real world paint and I can actually get hold of the owner (which is most of the time), then the owner is always a mine of information.

For all their sins, Carenado often have performance charts.
