What happens if FCPC's/ELAC's stop receiving CG info? Do they revert to some default gains, or work on last received CG?
That would mean dual FCMC, dual FMGEC and degraded (DIRECT) control law as FCSC in MASTER.
(as you can see in the diagram there is NO GW/CG connection to FCSCs).
Gains are defaulted at a safe value and depends on S/F position.
The FM section memorizes the last GW/CG value for internal purposes in case of power shutdown of FMGEC but
AFAIK this is not available to other equipment.
