B737 Cg/mac?
Good afternoon,
I'm interested to know a bit more about CG/MAC as it is used on the B737. First off, how is the figure calculated? Does it go straight from the loadsheet into the FMC? By inputting the CG/MAC % into the FMC does it then calculate all takeoff/cruise/landing trim settings automatically or do these figures still need to be manually calculated? Last question, is CG/MAC basically the same thing? Is it still generally known as a MAC on the B737 or CG? (I know it’s stated as CRZ CG on the PERF INIT page).
Any help would be greatly appreciated!
Cheers
