What is MTBF?

(a) Mean Time Before Fracture

(b) Minimum Time Between Failures

(c) Maximum Time Between Failures

(d) Mean Time Between Failures

I got this question during an interview for a job.

Question is taken from Redundancy and Failure Survival in FBW topic in section Fly by Wire Flight Control of Avionics

Correct option is (d) Mean Time Between Failures

Easiest explanation: MTBF is abbreviated as Mean Time Between Failures. It is the predicted time between two inherent failures of a system. The mean time between failures, or MTBF, of a single channel FBW system is in the region of 3,000 hours. The FBW system must thus possess redundancy with multiple parallel channels so that it is able to survive at least two failures if these very low failure probability figures are to be met.
