Two of the key activities in programs to develop higher levels of helicopter equipment reliability are test activities: reliability problem-identification testing and reliability demonstration testing. This document introduces the variables that must be dealt with in testing: demonstrated mean time between failures (MTBF), desired level of confidence, demonstration duration, and probability of passing. It also explains their relationships and the testing strategy which derives from the fact that helicopter hardware must have a real MTBF greater than demonstrated MTBF in order to have a resonable probability of passing a prescribed demonstration.
