1. The Audio Tab
Here you can choose the audio device you wish to use for your microphone to talk to pilots and controllers, and the audio device to use as the output device for listening to voice transmissions from them. If the device is not yet plugged in, you will need to close the Settings window, plug in the device, and then re-open the Settings window.
2. The Push to Talk (PTT) Tab
In the Push to Talk (PTT) Assignment section, you can choose which keyboard key or joystick/yoke button you wish to use for PTT. Simply press the button labeled "Set new PTT Key or Button" and then press the keyboard key or joystick/yoke button that you want to use for PTT. The Pilot Client will detect the keystroke or button press and update the "Current PTT Assignment" accordingly.
3. The Model Matching Tab
Generally you only need to change the settings here if you want to change your default model. Please note - Depending upon the simulator you are flying this may display as 'Model Matching (MSFS)' or 'Model Matching (FSX)
3.1 The Advanced Tab
This section allows you to exclude models (either individually or as an entire folder) from use in model matching. You can also prioritize folders by rearranging them in this list using the "Move Up" and "Move Down" buttons. Folders higher in the list will be searched first for models to use to represent aircraft you encounter while flying online.
3.2 The Advanced Tab
Here you can add a custom model matching rule set by loading the file from your computer's hard drive. You might do this if you created your own file, or if you received a file from another user, or downloaded it from your VA's website. Custom rules files can be re-ordered to set the priority with which they will be used for model matching. Custom rule sets always take priority over the models found when the Pilot Client automatically scans your hard drive for installed models.
4. The Performance Tab
Here you can limit the number of aircraft that the Pilot Client will inject into the simulator. If you find your frame rate suffering when in a crowded area, reduce these numbers.
5. The Miscellaneous Tab
Here you can choose to have the Pilot Client automatically squawk Mode C when your aircraft becomes airborne. You should leave this checkbox unchecked if you are using an add-on aircraft that features SquawkBox transponder integration, since the Pilot Client will then be able to read the transponder mode directly from the aircraft's panel.
The checkbox labeled "Show incoming text messages in simulator" allows you to have any incoming radio messages or private messages displayed as text within the sim. This can be handy for users with a single monitor when the Pilot client is obscured by the simulator window.
