So as promised - Tried the Approach on RW27 at EGLC in the 737-800 simulator and lets just say we made it in but it weren't pretty! PM was calling unstable most of the way down the approach!! I think our VSI was around -1200ft or more, Flap 40 and Airspeed sat around 119kts!! Tanks were a tad over a tonne, I'll keep trying with some legal amounts but don't fancy my chances :-)
