Thanks for the reports.
1. INIT page B is only available when the engines are not running. You need to fill it in before the engines are started.
The A320 model was originally purchased from Aerosoft but has had many changes since then. Aerosoft is not involved in the development of our A320.
We have a large fleet of aircraft and all need to be addressed at some point. I cannot spent all my time on the A320, otherwise we would not have the Boeing 777 and 787 and Q400 by now. This is also a default aircraft not an add-on product. One add-on is usually more expensive than our entire simulator. You cannot expect the same level of detail from a default aircraft. Compared to other default simulator aircraft I think our A320 holds up quite well. Of course if you compare it to add-on aircraft of companies that spend 3+ years just on the A320 then you'll find some things that are missing.
2. Regarding the airbrake issues: Currently the slider only changes airbrakes when you have the assistance auto-cockpit enabled. The assistance also disengages when you manually set airbrakes so the throttle slider no longer does things to the airbrake automatically when you moved the lever in the cockpit. I'll add clickspots for the MB339 and F15 airbrakes.
Seeing that the officials have not been properly aware of the problem of the brake slider, I exclaimed that sometimes people to people communication is so difficult to understand
