2. Check your aircraft's flight plan. Make sure that the flight plan is properly entered into the aircraft's navigation system. You can do this by going to the "Navigation" menu and selecting "Flight Planner." In the "Flight Planner" window, make sure that the departure and destination airports are entered correctly and that the route is set up properly.
3. Check your aircraft's trim settings. Make sure that the aircraft is properly trimmed for flight. You can do this by using the trim controls in the cockpit. The trim controls are usually located on the yoke or control column.
4. Check your aircraft's weight and balance. Make sure that the aircraft is properly loaded and balanced. You can do this by using the weight and balance calculator in the aircraft's manual.
5. Check your weather conditions. Make sure that the weather conditions are appropriate for flight. You can do this by checking the weather report in the aircraft's navigation system or by using a real-world weather app.
6. Reinstall. Reinstalling the program may fix the issue.
If none of the above solutions work, you may need to reinstall Flight Simulator X.
