Per a new "Appendix K" to the FAA regulations, effective no later than Jan 1 2015, all new production Part 25 passenger aircraft will be subject to "ETOPS", regardless of the number of engines
Thanks tdracer, didn't know that.
It seems that some regulators come to similar conclusions as i pointed out earlier concerning extended operations for the multi-holers.
Now why would that be? Maybe because there were some decisions when losing one of four that needed a little looking into.
This what i slightly criticised and what you can abundantly read on this site: Some jockeys and operators are a little overconfident when it comes to the capability of their 4-holer limping on three. The regulators feel the need to intervene and put in some rules.
Never nice, but mostly provoked.
