Also, aircraft are certified to be able to complete take-off with one engine failure.
Thus, twin engines have to have basically 100% reserve, while the 4 engines only need to have 33% reserve (to make up for one engine failing).
- youngtaff 8y agoNorwegian currently have a 787 stuck in Iran with a broken engine, so I'm not sure they can take off with only one engine
- FabHK 8y agoFrom what I gather, certification requires that they can take off successfully if an engine fails during the take-off run (after V1). I doubt that they're allowed to leave with half the engines inoperational already.
