In revisiting FS98 I was stunned to discover that Proflight 98 came with a Learjet 35A with an apparently fully, or nearly fully functioning FMC panel (I was probably aware of it when I got ProFlight98 but just forgot about it over the years)!
A third party panel by Eric Ernst (which I picked up from FlightSim.com's file library) and modified by Sean Green, also has the Proflight98 FMC panel.
How does one add the Proflight FMC panel to an aircraft? I'd ask Sean Green directly, but he didn't include his email address in his readmefirst.txt file (chances are it probably wouldn't still be current anyway).
Incidentially, is there a way to update the database for the Proflight98 FMC panel?
