How do you find the flight training device identification number?

To find the flight training device identification number (FTD ID), you can typically look on the device itself, as it is often displayed on a label or plaque affixed to the unit. Alternatively, you can check the device's operating manual or documentation, where the FTD ID is usually listed. If you're using a specific flight training software or simulator, the FTD ID may also be accessible through the system's settings or information menu.
