Hope this helps.
I'm curious to why they call Precession a principle rather than just calling it an error. It makes it seem like it's necessary or a helpful thing for gyro operation. Wouldn't calling it One main principle and one main error make more sense than calling it two principle?
Also, I have never heard of Attitude Indicator error. This is facinating to me and I would like to learn more. Do you know where I can look this up? or find more about it? Especially the accerating/deccerlerating error.
