I see from your screenshot that you have multiplayer up and running.

Have look at this thread as it may be related to the issue you are describing:

A quick way to check if you are affected by this multiplayer issue is to go to options>data>multiplayer and set it to off.
With multiplayer off launch the same flight and see if you run into the same issues.
