Maybe the people at the FAA in the 1950s who wrote the so-called 60-minute rule missed your point, but I don't know what to tell you.

Maybe the people at the FAA in the 1950s who wrote the so-called 60-minute rule missed your point, but I don't know what to tell you.
- mannykannot 6y agoThe 60-minute rule does not explain or justify your 133% claim with respect to four-engined aircraft - in fact, it is evidence against it: in practice, four-engined airliners, unlike twins, could tolerate more than a single engine failure.
- nickff 6y agoI just looked at a few airliners, and the 2-engine aircraft all had significantly higher power to weight ratios than the 4-engine aircraft.
- mannykannot 6y agoThat does not justify your 133% figure, nor the explanation you gave for it. That explanation implied that four-engined airliners could only tolerate the loss of a single engine.
