Problem 20BSC

Redundancy in Aircraft Radios The FAA requires that commercial aircraft used for flying in instrument conditions must have two independent radios instead of one. Assume that for a typical flight, the probability of a radio failure is 0.0035. What is the probability that a particular flight will be threatened with the failure of both radios? Describe how the second independent radio increases safety in this case.
