Notes

FSFO includes internal normalization and recognition tolerance for a few phrases, especially around radio tuning and squawk entry. The primary user-facing phrases on this page are the ones you should document and recommend first.

If a command is not working, confirm that speech recognition is active, the selected speech engine is configured correctly, and that the command category is not disabled in Settings.

Radio and transponder commands can be blocked by the Disable Radio Cmds setting.
