ACAS inop
Hello,
Our MEL accept an INOP ACAS.
As far as know ACAS is mandatory since Jan 2000 in EU airspace for Aircraft heavier then 15000kgs.
I found an exemption form for test, delivery and maintenance flight.
So assuming that our ACAS is U/S the Aircraft should be grounded. Isn't it ?
Any document on this ?
Thanks,
