Mother of crap, let's just agree to disagree. I don't have an opinion on heavy aircraft doing this, but I've had to use the technique in a C310 twice, and I know I was pushing the limits. I simply pulled the left engine to idle over the numbers, left the right engine at approach power(18"/2300RPM), and wrestled her down. Obviously this is a right crosswind(BKL in the middle of winter, winds off the lake from the NW)

To solidify the many clarifications, yes I added additional airleron force to the right, due to airspeed reduction and the additional left yaw now available. Would I do it again.....probably if I was still flying boxes, and only if I was as proficient as I was when I was flying every night in the same planes.

I feel neither technique at X-winds above 25(or 30 for the heavier stuff) is probably anywhere considered smart for Pax operations. Pending your ability to get the mains down and have aligned to the runway with minimal drift is really what will make or break you, unless you have underwing engines that just got an asphault sandwich!

Good luck to all of you, just know your abilities and keep the dirty side down
