I'm not talking about minor flaws, but like BA 747 departing on 3 engines, selecting to continue to destination after complete electrical failure...and such. I'm fully aware, that it is absurd to delay a flight due a light bulb malfunction, but where is the limit? which bulb will be the ONE factor, to give a go/no-go signal to the crew?
you must certanly agree, that complete electrical failure is not something minor...
