Wouldn't it be great if it was all so black and white.
A couple of points - ETOPS - Extended Range TWIN-engined Operations. The A380 is a quad. therefore is exempt from TWIN rules. Let's drop the ETOPS rubbish now - it doesn't apply to a quad. That means the A380 can divert wherever the hell it likes - not directly to the nearest ETOPS airport.
Second - consider this. A twin has to be able to take off using one engine. That means each engine is overpowered for normal operations by at least a factor of 2. What impact does that have on (a) fuel burn and (b) maintenance costs? A quad has to get up on 3 engines, so has a much smaller level of required exceedance for each engine. There is, of course, a penalty in fuel burn and maintenance cost. What's better - 2 massive engines or 4 smaller ones?
So Focal, you reckon that anyone operating a quad is an idiot as well, then, do you? Twins have their place, as do quads - let's just face it. Want to be free of ETOPS constraints? A quad is your only option.
Personally I'm happy to trudge the Northe Atlantic in a twin. Am I as happy to go over the Pole? No I am not!
