Hello,
I apologize English is not my language
This is why you have certainly understood that I did not know how to operate the airbrakes, in reality it is since a Microsoft update that the lever has become inactive, how can I put it? It has become like an inoperative decoration.
Whether with the mouse or the programmed buttons or the keyboard, it no longer works.
On the 747 - 787 and other aircraft such as the CRJ or the Longitude, it can be operated with the mouse or the buttons, everything works.
