Nice explanation, but one point to correct. Flux valve sensors are suspended in the sealed case as indicated in the video. Since it is gravity which keeps the sensor axis vertical in order for it to accurately sense the horizontal component of the earth's magnetic field, it is free to move out of vertical with any acceleration force. It is susceptible to turn and acceleration errors, just as a floating compass card is. That is why the slaving rate of the gyro precession motor is kept slow. Most maneuvers which produce turning or acceleration errors are completed before the slaving motor can move the card more than a couple of degrees from an accurate heading. When the aircraft resumes unaccelerated flight, the flux valve will resume sensing accurate magnetic heading, and the slaving circuit will correct the card position by slaving the gyro, again at a slow rate, and usually without the pilot noticing the operation. However, when these systems are installed in a jet aircraft, the sustained acceleration of the aircraft during and after takeoff can cause substantial errors in any gyroscopic system, which will be corrected automatically after unaccelerated flight is achieved. Some AHRS systems use flux valve sensors, but they are not subject to acceleration errors because the system contain three-axis gyroscopes and accelerometers and a computer for instantaneous corrections.
Im currently studying for my instruments exam and this is literally the best explanation of the remote indicating compass I could find
This channel is just pure gold! Thanks for your effort! 👏
total layman, watched this for fun, still understood most of it bc it was so comprehensively explained
Outstanding explanation. Very concise. Thank you :)
Really well explained indeed. Many thanks.

Inertia navigation system
I use to struggle to understand this until i watch this video. Thank you so much !!!
형님 진짜로 유용한 정보를 알려줘서 고마워. 항공기를 공부하는 군인으로써 항상 고맙게 생각해.
I just join the membership. This helps me a lot with my study and teaching.
Thank you so much for your support! It helps a lot to keep this project moving forward.
Thanks for the very well explained video, I hope it helps with my Instrument exam for the ATPL!
This is an extremely useful video. Thank you for making it!
You are doing a great job! Keep it up!
Excellent explanation!
I have been blessed with your video, can you please upload video for Aircraft navigation?
Sure Edwin, I´ll upload videos about general navigation after finishing with the instrumentation ones.
amazing stuff! i don't know how i got a CPL without understanding this prior! thank you!!
Same here, amazing to know how this instrument works. I wish it was in more aircraft (especially those without EFIS displays)!
Perfectly clear
thanks a lot , well explained
Outstanding!
great!!! explanation
well done.
Very nice
just great
It is nice
upload more videos
Amazing explanation!
