A300 v1.13 - cannot release parking brake

[APFV]

Hi.

I´ve got an issue with the parking brake of the A300: I have prepared the plane completely in any aspect (loading, FCU, MCDU) and I am ready to taxi but the parking brake cannot be released. If I press the "v" key on the keyboard the parking brake handle twichtes a little bit, but it does not release the brake. If I simultaneously press the brake pedals while pressing the "v" the handle came out completely but does not turn and release the brake, but goes back into the set position.

The strange thing is that releasing the parking brake works without any problems in codl and dark state (and maybe somewhere between this state and fully prepared). Even if I release the parking brake in cold and dark state and secured the plane by the chocks somewhere in the prepeartion phase of the MCDU, the FMS, EFB or whatever the parking brake automatically activates and I cannot release it.

I would appreciate any help.

Hi @APFV, 

Firstly welcome to the forum 🙂 

Please take a video then upload it for us to review. 

Please also try and remove any key bindings and reattempt.

Cheers.

Hi Brad,

thank you!

First of all, the problem seems to be fixed. But nevertheless, something is weird.

The problem obviously is the calibration of the T.Flight Rudder Pedals (Thrustmaster). I assigned the toe brakes to them but there seems to be an issue with the end points. Even if the pedals are fully released there is so much brake power that the plane does not move even on full thrust. Recalibration does not fix it. Perhaps a custom curve does.

Additionally I misinterpreted the set position of the parking brake handle so the parking brake was NOT activated, different to what I wrote in the first thread. But the problem why I could not set the parking brake was the brake pressure coming from the pedals.

I did not know that the A300 automatically releases the parking brake when braking with the pedals. I guess you modeled that correctly. That is why I did not notice that there has to be brake pressure coming from the pedals. A modern Airbus does not have automatic release. Some flight simulation models does have and call it "intelligent parking brake".

Thanks for your help.

And by the way: these planes are an impressive work!
