I’ll disagree a touch and argue that in a thread headlined ‘long flight over water’, ETOPS (AKA Engine(s) Turn Or Passengers Swim), while a piece of jargon, isn’t an obnoxious or unexpected one. And at least the pilots in the thread have been sparing with the jargon so far. YMMV.
Question I had for them was in the twin engines, takeoff regime, and an engine fails. There is a minimum flight speed below which the airplane may be above stall speed for a particular configuration, yet may not be able to maintain roll or yaw control. Having only one engine only producing thrust, and that asymmetrically to the centerline for the vast majority of twins, induces a yaw and a roll moment to the aircraft. My question is: do those moments increase appreciably with increased thrust, such that the speed at which roll and yaw control may still be maintained also changes appreciably?
IOW, if Vmc for a particular twin is (total WAG) 70 knots, does that speed vary appreciably depending on whether the engine is making 50 percent power, or 120 percent+ rated power?
Just trying to figure out if there’s a time where passing Vref, the aircraft rotates, gets up in the air, then loses the engine, where opening the throttle all of the way might cause more problems than it solves.
