AA62,
I was only trying to clarify what you were taking about. I have dealt with civil aircraft for some years now. ADR - to me - means Air Data Recorder..a totally different thing.
My only dealing with similar systems in the military involved two (Mk1) Chinooks which were fitted with HODR in the 80s, (Helicopter On-board Data Recorder) but both proved hopeless as they relied on "bog standard" cassette tapes which sadly melted just when at least one was needed, but, instead of upgrading the system to a metal media "they" just scrapped the idea. Or that's how it seemed to me at the time. As far as I know there is still no FDR or CVR systems fitted to Chinooks, the one helicopter that is regulary described and the most inherently dangerous (not by me though).
