Ah, cheers hans. My memory playing tricks here it seems. I just checked and found this -
https://www.faa.gov/foia/electronic_...TS_Summary.pdf. Safety Item #2, page 7. Semreh, my apologies to you - it was my poor memory after all!
As an aside, I don't recall seeing the FAA doc at the link so may be of interest to others - unless it was only me who missed that too!! It seems quite comprehensive (at first glance) covering both tech and administrative issues (such as FAA oversight). Anyway, back under my stone before I confuse people even more.
