B737 Question about FAC & G/P FMA
Currently trying to get some pre-studying done before I go for my initial type-rating next week, I noticed an image of the PFD DU with FAC (Final Approach Course) in the roll mode and G/P (Glide Path) in the pitch mode on the FMA.
I can't seem to find any detailed information about this, and was wondering if there by chance is someone that knows more.
I've been told it has to do with something called IAN (Integrated Approach Navigation?), but don't have knowledge about this either.
Having never flown transport aircraft previously either, I am still trying to wrap my head around the documentation.
Thanks!
