Quelch, I'm confused!!????? Why does a pilot flying on a CAA/FAA licence need an FAA BFR? So far as I'm aware, an FAA BFR is not required except for somebody flying on an FAA Licence. Us Brits only need to ensure that we have the CAA/JAA BFR and a current medical to ensure that our licence is current and then get an FAA conversion in the USA at a Flight Standards Office. An FAA BFR counts for nothing because without the UK BFR on our CAA/JAA licence, the FAA conversion is not valid anyway.
I've posted this same question on an identical posting of yours - Nothing to do with uplift aviation by any chance are you?
