Similar learning experience as F/O PF, well anticipated by one of the older more wizened brigade of captain as was more common in those days. LGW, high traffic flow, the common "expect late landing clearance" i.e. around 200' and B747 lined up & cleared to go. Old wizened LHS warned to beware of turbulence and speed fluctuations as the beast ahead rolled. Don't over control on thrust nor flt controls. Firm and decisive. He was correct. Rock & roll <200'.
A message to pass on whenever I could.
Off thread, but there was also another message passed on, learnt from an interesting upset report, of medium a/c passing behind a heavy at crz FL. They had the mandatory separation, but hit the rough wake and went to significant bank angle. Not nice at night. After my first encounter of similar scenario, whenever I was vectored to pass behind a crossing a/c, I always asked what type, and if close behind a heavy nudged up 100'. It could also hit you if further away and 1000' below; a bit like being in trail on NAT tracks.
Sorry for the drift.
