Forum members, Lend me your ears.
I am reviewing RTCA/DO-160C qualification data for some aircraft engine monitor gauges (rpm, temperature at various points). These devices date back ten years, plus they were qualified by similarity to an earlier design - how much earlier is not stated. My question is whether any forum members have a feel for how tight this TSO process really is. It is hard for me to imagine that every part in these gauges is built exactly like it was ten years ago, or more. I can see where the individual component part numbers would need to be the same, but is there any guarantee that the dc/dc converter manufacturer is building his product the same way, even if he uses the same part number? What about integrated circuits in general over such a span of years?
