Hi Guillaune, thank you so much again for your help, I reviewed the links you have sent me and they are very useful, but as you could see on the Cessna 3D Cockpit, the flight instruments are analogous - the altimeter for example -, but on some variants of the aircraft the flight data are displayed on an integrated flight instrument –garmin 1000-, so I would like to know if I could create, edit or modify my own Primary flight display and Multi-Function Display to full simulate inside X Plane this specific aircraft instrument.
Thanks
Regards
