For the Cessna Caravan (Cargo Medium missions), the pre-made flight plan always has a cruising altitude of FL 450. This is craziness because the service ceiling of the Caravan is 25,000 ft. You either have to manually edit the cruise altitude and file it to the ATC before every mission, or keep hearing “please expedite your climb to FL 450” for hours on end.
Almost every aircraft I’ve flown in Career mode have completely wrong cruising altitudes set in the EFB before missions. This was clearly never tested beforehand.
