Thanks to all that have responded... some very useful tips... much appreciated... On the face of it it would seem a pretty spectacular piece of kit.. like most old F*rts I would still appreciate a dinner plate sized illuminated Red Button within easy reach that could be punched when I wanted some good old raw data and hands on flying... But I went through this distrustful mode when first dealing with EFIS years ago and got to love it ... once again... thanks to all...
