Just a quick, hypothetical question.
If the engines MUST meet required standards of SAY, 1 failure per 100,000 hours, and there are two aircraft, both brand new- one twin and one quad.
MAthematically, they will BOTH not have a failure in the 100,000 hours prescribed, but, once both aircraft have done the 100,000 hours, and PRESUME that they are running on the same engines as when new, then they could BOTH expect to have A failure.
IF however, after 100,000 hours, the engines WILL have a failure, then of course, the quad will have twice as many failures than the twin, hence twice the probability.
Of course if ALL engines fail at 100,000 hours, then both aircraft are in the
.
The question is : if they lose all six engines, what is the probability that they will run into each other on the way down? (presuming that the quad will fall faster than the twin due heavier weight)
