When Pilot2ATC connects, there will be 3 lines in the Speech Text Window at the bottom right and the Connect button will turn green and the text will change to Connected. The last line in the Speech Text Window will be "Grammars Loaded".
“Simulator Disconnected” will appear on the second press of the Connect button as it disconnects from the SIM.
Also, the Yellow aircraft representing your aircraft will be visible on the map.
Here are the most common things to check when you get a partial connect:
⦁ If connected but the radios aren’t working, check the Battery and Avionics switches on or the “Ignore battery” and “Ignore Avionics” options are checked in P2A Config
⦁ If it seems to partially connect but the Connect button does not turn Green, set the Weather option to a different source such as NOAA Real Time Weather and try again.
⦁ still won't fully connect, try deleting the AppConfig.xml file. You will lose your Config settings, but some users have reported that this fixed their connection issue. The file is located at:
where <UserName> is your PC user name. Portions of the path may be hidden by default, so be sure Windows Explorer has Show Hidden Items checked in the View tab.
⦁ If connecting to MSFS, one user reported that setting FSUIPC WASM to Enabled fixed it for them.
If none of the above does it, try deleting your current installation and installing the full version to a fresh location.
