“Last I saw, the only twin engine airliner allowed to do that is the 777.”

OLD NEWS....
That hasn’t been the case for over a decade now.

Yeah, someone already pointed that out to me. Since I picked the wrong week to quit amphetamines, I forgot about my trip across the Atlantic on a 767. In fact, of all my trips across the Atlantic, only once was it on a 777.

So I looked into ETOPS. The 767 was the first ETOPS aircraft. Previous to ETOPS, twin engines were restricted to 60 minutes from a landing strip. In 1985, the 767 was allowed 120 minutes. In 1988, there was a 180 minute provision for aircraft with one year of trouble-free 120 minute ETOPS. The 777 was the first aircraft to have 180 ETOPS on entry to service.

Since 180 ETOPS covers about 95% of the world, I suppose that is where I bungled the 777 factoid. No more shootin’ from the hip for me.

And of course, ETOPS is for the US. The Euros were doing a 90 minute rule for the A300 back in the 70’s.
