And the TB20 can fly on UL94 as well.
Have you got the ref for that?
I recall seeing something recently which suggested the IO540-C4 might be fairly close to it, but it was a bit ambiguous.
It's not the TOTAL UL91 though, which is the stuff everybody (well, Rod1
) in the UK is banging on about. Who is actually proposing to sell UL94 in Europe?
