I was sitting in the right seat of an MD83 about 15 years ago, when the old guy misjudged a visual approach and put it in a full-rudder-deflection sideslip to lose altitude on finals...
Whilst he did it smoothly enough so i didn't worry about structure, and had enough speed on not to worry too much about stall margins, I SWEAR i saw the EGT of the "downwind" engine rise about 100 degrees, enough to start me sweating... something else to think about when u sideslip an airplane with this kind of engine configuration...
