In this episode, we break down how modern aircraft determine attitude and heading, and why today’s systems are far more reliable than the spinning gyros of the past. We explore the evolution from free gyros to solid-state Attitude and Heading Reference Systems (AHRS), explaining how laser-based sensors and magnetometers work together to provide accurate pitch, bank, and heading information without the risk of tumbling. You’ll learn how the flux gate compass senses the Earth’s magnetic field, how remote indicating compass systems reduce magnetic interference, and why slaved gyros automatically stay aligned while free gyros demand constant pilot attention. We also cover common limitations and errors, from precession and vacuum failures to startup and taxi checks, and tie it all together with real cockpit instruments like the HSI and RMI. This episode is a practical, pilot-focused look at the technology quietly keeping you oriented in every phase of flight.
