Hi everyone,´
I have build a three brake pressure A320 gauge, obviously to be operated with mobiflight. The pressure gauge is made of three mini servos and is working almost perfectly with the exception of what I am going to explain. When the aircraft is powered the application of parking brake sends a signal to the pressure gauge, changing the values shown. So basically it shows the same value/movement than the VR cockpit gauge.
The problem arrives when the aircraft is unpowered, basically cold and dark cockpit. In this situation the VR cockpit shows a gauge with its needles showing zero, since essentially there is no electrical power to the system. While this happens it does not mean there is no pressure in the brake system, simply it is not shown since there is no electrical power. And here does the problem start, at each application of the parking brake lever, the servos move! even the aircraft is electrically unpowered. A closer look at MF shows the flight sim values to show the pressure in the system, and here is where the problem basically is. MF is doing the right thing, by providing the actual brake pressure value, but there is no separation for an unpowered aircraft or a powered one.
Any help is appreciated.

Thanks in advance,

Daniel
