All,
To quote Joe Sutter, late of Boeing some years ago, when I this asked the question, the answer was: “if the manual doesn’t prohibit it, the can do it”.
It was prohibited on the 707, because at that time SFAR 422B Certification did nt include it, any wiping engines of a pylon in an unintentional slip was demonstrated on more than one occasion.
All the 747's, up to the 744 slip quite nicely, and the quite moderate actual angle of bank and out of balance forces than can produce quite a useful increase in RoD, if you get it right, won’t spill anybody’s G&T.
All the rules you were taught in basic training still apply, regardless of the size of the aircraft.
As for the suggestions that a missed approach is the “professional” answer, firstly I hope nobody is suggesting continuing this or any similar maneuver within the “stable approach” envelope, usually 1000 agl and down.
Secondly ATC planning only ever accommodates a missed approach a second best option, ATC can suffer from getinitis as badly as a pilot.
Tootle pip !!
