Subject: MIL STD 471 - M. Demo
I'm planning a Maintainability Demonstration. There are MTTR and MaxTTR requirements at each of 3 levels of maintenance. I wanted to use Test Method 8 in MIL-STD-471A in hopes of avoiding 50 observations on 6 different specifications (which the other methods seem to require). However, the DS-level MTTR spec. is 2 hours (greater than the 100 minute limitation called out in the second paragraph of the method). I can't figure out how important that 100 minute limitation is. In other words, is it possible to "cheat" by 20 minutes, or is there a workaround for longer MTTRs? Anybody know?
