SC: "We do all understand the differences between ACMS, CFDS, CMS and ACARS don't we."
Yes, I used the abbrev. ACMS, a Boeing term, when it should have been CFDS. At least it was CFDS at A/B back in the beginning of condition monitoring. The two systems differed in construction, but the resulting output to the ACARS is effectively the same. Has A/B replaced CFDS with something else when I wasn't looking? ACMS and CFDS required different outputs from the LRUs, and so unique part numbers.
