Re: Cross controls on a 747 or other big jet/turbo prop
I don't think it would be greatly effective or advisable on a 747, but on a 737 Simulator all engines out glide landing practice, I was very high, with the instructor and copilot very amusedly waiting for the inevitable. Full speedbrake and telling them 'I have one more trick up my sleeve!' and doing a strong cross control brouoght us down onto the threshold a treat. No reason why it shouldn't work, but the 747 with full flap would be draggy enough.
