This question is specific to Bombardier C-Series aircraft which has three modes: Flight control computer normal mode, FCC Direct mode and REU direct mode: (I am not sure if other aircraft have an intermediate mode before switching to alternate law)
Control law gains are computed for both FCC normal and FCC direct mode even if the computer is in normal mode. Direct mode commands are outputted when the switch happens from normal to direct.
Fly By Wire Flight control computer switches from normal law to alternative law under certain conditions (when minimum required sensor set is lost for instance). So I assume the control laws are also switched from normal to direct. Are the direct mode control gains computed and monitored when the flight control system is under normal law?
