3WF is equipped with Garmin’s Electronic Stability and Protection safety system which is activated by default every time you turn on the avionics.
For any and all training flights with the intention to practice flight maneuvers please make sure to deactivate ESP (see the Pre-/Postflight section at the top of the Before You Fly 3WF… page) so as to avoid ending up in a fight with the Autopilot.
The feature will turn itself back on for the next flight, so don’t worry if you forget to re-activate it.
If you intend to fly X/C without maneuver practice there is no action item; ESP will simply be automatically ready to assist should the need arise.
For more information about ESP see chapter 8.10 in the G3X Touch Pilot’s Guide.
