* Termination switch channel
*
* Use this channel to trigger flight termination. When flight termination is activated,
* PX4 disables all controllers and sets all PWM outputs to their failsafe values.
* This channel triggers irreversible flight termination:
* All outputs are disabled and set to their failsafe values (disarmed by default)
* and MAVLink parachutes are triggered.
*
* Note: Flight termination is irreversible—once triggered, it cannot be undone.
* This is unlike a kill switch, which can be toggled back. Use with caution.
* Unlike a kill switch, this cannot be undone until system reboot. Use with caution.
