visionOS dev tools suggest 'Travel Mode' for airplanes

Strings found in the developer beta of visionOS suggest that Vision Pro will require entering a “Travel Mode” to operate on an airplane. This mode requires the user to remain stationary, disables the realtime digital persona representation, and disables ‘some awareness features.’

The text strings also include a message warning that the current fit could reduce gaze accuracy, though it is unclear if this is related at all to travel mode or simply poor headset fit.

Personally, I’m curious if travel mode will increase battery life by any significant amount. With the 2 hour battery life cutting things close when watching a movie, extending that runtime to 3 hours or so would be excellent. It will remain to be seen how much Vision Pro sacrifices in travel mode, and how this affects the experience.
