Free : Boeing 777-200LR Derate Calculator

777-200LR Derate Calculator table

Already author of a preflight briefing tool for PMDG 737 NGX, Lasse Kronborg came today in PMDG forum to announce the release of his Derate Calculator table for Boeing 777-200LR. The XLSX file can be used in Microsoft Excel, or other free solutions like Google Docs web app or Open Office software. For now, it’s able to indicate if the runway length and ground conditions, combined with your takeoff weight.. allow a takeoff derate. “Fooling around” the TO derate  and the assumed temperature by yourself, you can find the best combination until there is a 77W profile for TOPCAT.

It looks like other forum members are giving a hand to turn it as an EXE file not to need a table environment, and for a better user interface. Nice work guys !
