Two minutes is not all that long
It's £6 to a rental pilot.
Yeah, but the time is still going in your logbook...
I was once flying somewhat line astern in my 150, behind a buddy in his 150. His vortex stood me hard on my wingtip, and spit me out - I learned! Same weight aircraft is all it takes to put you over. If not "at altitude", you're in big trouble!
Vortex avoidance is one thing which a good crosswind greatly aids. Many has been the time I have satisfied myself as to the direction that the vortex has been blown, and I've operated well to the upwind side, with no problem. In the video clip, it is apparent that there is little to no wind, so the vortexes will just hang there stationary, until the dissipate - probably in £6 or so.....
It's interesting to observe while a pax in a window seat, behind the wing on an airliner, that once a whole lot of flap is extended, the vortex is generated off the outboard end of the flap, rather than the wing tip. This has negligible bearing on avoidance though....
