Performance graphs

This may be a dumb question!
Is it possible to enter the performance data for your a/c?
I'm thinking along the lines of hot & high, full fuel, full pax etc, it would be nice to be able to punch in your data like you do on the w&b screen and see if you're within the performance envelope.

I like this idea!

As I understand it now commercial jets have equipment that does this now and its called FMS. probably a little too much to ask for us kids with our toys!

This is an interesting idea but there are currently no plans for implementation.
