The author discusses the disassembly and reverse-engineering of an attitude indicator for the F-4 fighter plane, a complex instrument used to show the aircraft’s orientation in three axes, including azimuth. The post explores the mechanical and electrical construction of the indicator, highlighting the rotating ball mechanism and the motors responsible for its movement, controlled by servo loops. The post delves into the amplifier assembly and pitch trim circuit, explaining the pilot’s ability to adjust the indicator for different flight scenarios. The post concludes with a comparison to modern digital cockpit displays in newer fighter planes.
