Dave,
Fully familiar of the difference between the ETOPS 140/180 minute rules. My question is how that affects the 1 hour ETOPS distance... Say we call the ETOPS distance 400nm the max ETOPS diversion distance is 3x400=1200nm for 180min or 14/6*400=933nm for the 140min rule. In my mind though, that doesn't affect the 1 hour ETOPS distance which would stay at 400nm.
Also... I've flown many 787's with Trent TEN and pack B engines with no limitation below 180min, and also many pack C engines (obviously with less than 300 cycles on them) which were also 180min so where broompusher stated the limitation for all Trent 1000's on a 787 is 352nm it raised my curiosity level.
