charraeus Posted June 4, 2016 Report Posted June 4, 2016 Hi, ... did not find it in the "charts-document". How can I determine/calculate the optimal cruising flight level when the route distance is given?
mgeiss Posted June 4, 2016 Report Posted June 4, 2016 (edited) I don't know if it's optimal, but I use the following as a roule of thumb and it works fine for me: Short flights under 180-200nm: Flight level = distance rounded up and adjusted to even/odd thousands for westbound/eastbound ops Longer flights: FL180 or FL190 if heavy, FL200 or FL210 if light Edited June 4, 2016 by mgeiss
Tchou Posted June 4, 2016 Report Posted June 4, 2016 Simbrief will give you a nice optimal cruise FL, also with Cost Index and such things like wind component and ISA dev (those thinks you never know what to put in) Fuel Calculations and so on. Optimal FL takes into account the distance, the Weight of the plane the CI, and the winds. www.simbrief.com (it's free, you have to register to let it save your flightplans and your preferences and also your fleet).
charraeus Posted June 4, 2016 Author Report Posted June 4, 2016 Thank's a lot. The rule of thumb is very helpful. And I will check Simbrief.
