Alessio75 3 Posted April 29, 2020 Share Posted April 29, 2020 Hi, During my short flights (i.e. LIMC-LIRF) the Perf MCDU page often calculates a cruise of FL370. But at that altitude I get only a short cruise (the descent CL triggers very soon). Thus often I decide to fly at FL300 or so. Why MCDU calculates so high FL? Does it consider only the airctaft weight? Link to comment Share on other sites More sharing options...
SpottyMCapt 1 Posted November 5, 2020 Share Posted November 5, 2020 The FMS computes a parabola as the most efficient profile. Air traffic control would think differently. Link to comment Share on other sites More sharing options...
