air temperatures at cruise altitude?
vapilot2004:
Thanks for your insights and your list of airlines currently operating the RR-equipped 777-200ER. I note that Air New Zealand also operates this type/engine combination; eight of them I believe. Which brings me to a question I'm hoping some of you pilots can answer for me (I'm not a pilot and so thanks for allowing me to participate in this thread without hopefully generating too much eyerolling from you):
In terms of typical cruise altitudes and air temperatures at those altitudes, are there any significant differences between the northern routes on which the BA and Delta rollbacks occurred, and NZ's AKL-YVR cross-equatorial route which they fly non-stop with the 777? This is a 14-hour ETOPS route.
