While flying for more than 30 years on jets I’ve been on 3-engine (DC-10, MD-11) and 4-engine (A-340) for more than 20 years. The only engine failure I encountered was on the MD-11 homebound from Singapore while cruising. Nothing dramatic, as we set MCT-power, kept flying cruise-level and I decided to land at Budapest instead of our destination Zurich.
But it will be different on a A-330, a plane that I flew for 7 years. Encountering a engine failure tracking over the atlantic not only makes you thinking about ETOPS requirements but also about your service ceiling. You will be going off-track and descending through several levels and end up maybe at FL 180 with considerable reduced range looking for a suitable alternate.
It was learned at my company that it would be a good idea to call for a MAYDAY with a engine failure on a 2-engine-jet as most probably assistance from ATC is needed...
By the way: terrain problems at Manchester?
