So I did a hop from Miami to a small Carribean island, 1390nm. My tanks read empty as a came in to land.The King air should be able to make 1500nm IIRC.I was cruising at FL290, 450lb/h fuel flow, 1600 RPM.Obviously I need to drop that, but by how much? What is a good throttle setting to maximize range?Thanks for any tips.

Try flying a bit higher (the King Air can do FL310 or something like that). If you're flying "realistically", I think the B200 is RVSM too. Try also 1700RPM and a power setting that gives you around 300lb/hr/engine. Watch your ITT and your torque at high altitudes.Best regards
