Now that would have been something to see.
Folks,
The B767 side-slips very nicely, indeed it even does it on auto-pilot coupled approaches with a cross-wind, as did the L1011.
The B747-400 was mix and match, on a coupled approach it was part side-slip and part offset heading for drift, as too much "wing down" could result in a serious seniority scraper. Hand flying, it side-slipped very nicely.
There are no AFM side-slip limitations for either of the above.
Tootle pip!!
