Craggy the Vasi is based on 2.8 for 13L but the actual angle assuming you cross DMYHL at 1000’ is more like 2.5 and is the reason why those unfamiliar on the bus using FPA screw it up as they go straight to 2.8 without ever considering the extra distance flown due to the turn.
Much easier on the Boeing..click off the AP and 500fpm till the Vasis look good then 6-700fpm at 145kts GS
