i tried researching using '' coarse ''
i understood a few bits of the system is that when there is a disgreement between the altimeter reading and the ADC the coarse mode takes over , and that a coarse mode provides more of an altitude increment when its synchro rotor is spun through 360 degrees than the fine mode .
but nothing much i could find about it, there is a lack of information in google about this subject .
i tried going back to my EASA 66 notes to check it up but the notes werent very enlightening in this topic,
its really confusing i just want someone to explain to me this system in a brief manner without using big words like '' coarse staircase '' so i can comprehend.
i know how a control synchro works i know how the ADC works and i know the principle of an altimeter its just this little part is creating a confusion to me .
