Care to enlighten us how ETOPS can kill a four-engine aircraft?
Its a very very simple concept that is proving correct.
In a nutshell the largest advantage quads had over twins is diminishing. ETOPS is at a point that there is almost no where an Quad can fly that a Twin can't.
If you look at the routes long haul twins are flying today, a lot of them were once strictly a quad preserve, due to ETOPS limitations.
As I tried to explain on the forum.... quads are no longer a necessity for long haul.
Twins are the new kids on the block and they're here to stay.
And the fabulously stupid idea that quads are cheaper to run that twin is very wrong. There are a few advantages with a quad...
But as this article highlights Twins are now the prefered long hauler for their superior economics
