I switched off engines 3 and 4 just after lift off and returned to the airport. Aircraft is over max. landing weight, there is no time to dump fuel.
Note: We train this in the “real” simulator . However, it is manageable only after lift off or during very low speeds in the take off run… If 2 engines fail on 1 side between V1 and Vr you will loose control over the aircraft, immediately veer of the runway and hopefully have the time for your last PA call : “Crash!”
