Thanks for the feedback folks. With the age of our FMGCs and the lack of spares this issue is becoming real ugly real quick here with little support from Airbus in terms Flt Ops concerns re Safety.
As you all agreed, into busier dest'ns, below 10000, I just don't see how you can operate without relaxing a level of safety.
New or upgraded units are something like a 1/4 mill apiece so you can imagine the reaction to the obvious solution in recessionary times. Still fighting for it though.
Anyway's, thanks again for the feedback. Twas much appreciated.
