Message:
I appreciate if someone could provide the definition and its source for these terms below.
1. Mean Calendar Time Between Failure (MCTBF)
2. What is the terminology for 1/MCTBF?
3. What is the Mean Corrective Time Between Failures?
Thank you, Andy

MTBCF = Meant Time Between Critical Failure This is the effective MTBF of a system with redundancy. 1/MTBCF = effective system failure rate with redundancy. Mean Corrective Time Bewteen Failures may be the logistics MTBF. The system could be still running, but a redundant component could have failed.
