You need to turn off AI Copilot ATC radio handling assistance, and only turn them on when you want it to.
For me, when I’m cold and dark, I always check to make sure my AI Copilot ATC radio handling assistance is off before I even turn on the battery. So after I turn on the battery, the Copilot stay silent while I do all the tasks. Then I request pushback and once the engine start and ready, that’s when I turn on the AI Copilot ATC radio handling assistance so they can take over the handling from that point on.
And at the end of the flight, just before I park the aircraft turn off the AI Copilot ATC radio handling so that it doesn’t carry over into the saved config file for the next flight.
