I'm about to change aeroplanes so, as I am based within the Luton Zone I have to change out the Narco 810 that works perfectly well..... Thanks for nothing EASA
A bit of research has turned up the following:
Dittel Avionik KRT2 - £999
Funkwerk ATR 833 - £1,194
Becker AR6201 - £1,434
All fit a 2 1/4" instrument hole which is handy but will leave a Narco 810 sized hole in the panel.....
