Almost all the FAA guidance about en route wake avoidance is information about head-on or same direction flight paths. What about perpendicular courses?
At FL400 ATC advises of a A380 11'oclock 7 miles 1000 above us "caution wake turbulence." At the time our flightpath would have us passing 3-5 miles behind it perpendicular to his track. What is the best course of action here? Maintain course and take the wake on directly? Take a turn to hit it at a 30 degree offset of its path? Being only a few miles away would it be better to turn towards the direction of the crossing aircraft path or away from its direction of flight putting you further behind the aircraft?
My current knowledge of wake vortices are 3-500 fpm decent up to about 1500ft. Then it stops descending and just spins itself out. We made a call that, looking back on it now, I think was the wrong call. However, we passed through the flight path of the aircraft without incident and did not encounter the wake. But I believe it was luck rather than "our"/"PF's" decision. So with that being said, what is the consensus here? I don't remember any guidance or procedures from my time at the regional level. And we haven't discussed it at during any of my biz-jet training. Can I not find any FAA information on it because it's a non-issue?
