1.	What is the failure probability figure of a commercial aircraft?(a) 1×10^-4/hr(b) 1×10^-6/hr(c) 1×10^-11/hr(d) 1×10^-20/hrThe question was asked by my college director while I was bunking the class.The origin of the question is Redundancy and Failure Survival in FBW in section Fly by Wire Flight Control of Avionics
Answer» CORRECT choice is (b) 1×10^-6/hr Easiest EXPLANATION: The statistical level of safety currently being achieved with civil aircraft transport corresponds to a figure of around 1 × 10^-6/hour. This figure is derived from the TOTAL number of civil aircraft crashes OCCURRING in a year from all causes divided by the total number of aircraft flying and their annual operating hours.
