There’s no real way to measure “gravity” in a plane, unfortunately.
AoA is about airflow directions anyway, so wind angle plays a role too, beyond just plane angle to the ground.

- zamfi 8y ago> Suspended mass inside container fixed to plane structure, measure angle of mass relative to container? Unfortunately not! This measures acceleration of the airframe, not gravity. Was a huge challenge in the early days of flight, and there’s a great history online that I can’t find right now. Anyway, this might be useful reading: https://en.wikipedia.org/wiki/Attitude_indicator https://en.wikipedia.org/wiki/Attitude_indicator > That doesn't sound desirable though, is it? Given that wing-angle-to-airflow is what matters when it comes to stalls, I’d say it’s eminently desirable?
- peteradio 8y agoThat is how lift is created. Air currents are not consistent over the plane. Sometimes they could more downward which would require a pitch up of the wings to catch and create lift. This is not the same as perpendicular to gravity which is easily measured in the plane. This is an entirely different animal.
