I managed to install Pilot2ATC + Navigraph, I established established Pilot2ATC connection with X-plane. I enter the Pilot2ATC flight plan, validate it and request clearence.

A voice repeats to me all the time "..i need yours breaks OFF.", I release the brakes, while the engine is not started, the plane backs up alone until it puts in a position lambda in full middle and there silence over "..i need yours breaks OFF."

I do not understand absolutely anything that causes this. Please, if you could help me?

That's probably not P2ATC that is sending you that message, what plane are you using? What other plugins do you have installed?

Sounds like a ground handling program trying to do a pushback. 

Exact !!! thank you very much for giving me the track.

Here is what happened.

Two years ago when I bought X-plane and joystick, I gave the joystick keys the pushback functions of X-plane. I have never used it because I have better pushback and I forgot.

When I configured Pilot2ATC, it asks to give joystick keys. There, I attributed the same keys as those given to the pusback of X-plane !!!

So when I activate the joystick Pilot2ATC worked and the plane was doing a pushback !!! That's why a voice asked me: "i need yours breaks OFF".

I corrected this mistake and everything works fine.

Thank you very much and very much.
