Even single handedly control an aircraft with engine failure at take-off.
meaning???
Yeah obviously YOU control the aircraft on an EFATO, assisted by the Captain/First Officer. But I can guarantee you that no one I know during my course or who flies for other airlines have had a practice at an EFATO whilst the Captain/First Officer gets incapacitated at the same time.... Yeah during the T/O roll maybe, and whilst already single engine, but not when the EFATO happens.
