Vortices
What better place to ask this question ?
Some years ago flying night freight ( E110 Bandit ) into Frankfurt we had a rather nasty experience ...on approach to 27L ...737 ahead almost at touchdown and us 6 miles out....fierce winds ...50+ knts, 50 Deg off at 2000 ft.... suddenly we're out of control...doing a wingover and losing 7 to 800 ft breaking away to the left...turns out that there was a heavy 3 miles ahead on 27R and his vortex had been pushed across by the wind...I'd never heard of this during training or in any crew room chats...any of you excellant ATC types had experience of this happening... any of you aware that it could happen.. ?
