The minimum requirement for BRNAV is a VOR/DME -based system
capable of storing at least 4 waypoints.

I have European approval on my Piper Turbo Arrow with a
King KNS-80 as the RNAV box.


Yes, the KNS-80 RNAV was OK for this, but not any more because it does
not meet the CAA FM Immunity requirements. (this requirement claims to
address the proximity of the FM broadcast band to the FM aviation
band; not that anybody has ever come across any problems but the UK
CAA says so...)


That's taken care of with a suitable preselection filter from King.

The airplane (OH-PYM) is BRNAV capable and approved now.
