- Reverse-engineering a three-axis attitude indicator from the F-4 fighter plane (righto.com)
We recently received an attitude indicator for the F-4 fighter plane, an instrument that uses a rotating ball to show the aircraft’s orientation and direction. In a normal aircraft, the artificial horizon shows the orientation in two axes (pitch and roll), but the F-4 indicator uses a rotating ball to show the orientation in three axes, adding azimuth (yaw).1 It wasn’t obvious to me how the ball could rotate in three axes: how could it turn in every direction and still remain attached to the instrument?
