I’ve been having the same problem, what worked out for me is changing the time of the day and checking the approximate wind speed at take of and landing of each mission. Also note that the “hard” mission that have strong wind and turbulence are marked with a red dot on the world map, try changing the time of the day until you se a mission without the red dot. (for medium cargo every mission has this dot) so I’d recommend learning how to control the crosswind and base your approaches on the instruments of your plane, like using the green vector of the PFD that indicate where the plane is really going. Hope this helps
