OQAR
KLM have OQAR's fitted to some of their fleet. I know this as I was involved in installing them in 2 of their a/c. This was a full upgrade on their -5/6/700's aquired when they merged with Air UK, including additional wiring for extra parameters.
However, I have a feeling there is a slot in upgrade, where you take out the old floppy style QAR and just put in the new OQAR.
Check out Boeing for a relevant STC.
Why they can't just integrate the DFDAU and OQAR I will never know!
