Beat that stuff to death, eh? Well, next on the setup is the Mep. SOP tells me to select both F/D's to ON. When I do, I get the pitch and roll bars on my ADI. Where do they come from') Always?
The F/D signal comes from whichever FCC is selected on the INSTR SOURCE SEL panel. -ormally, the Capt is set to the L, and the FO is set to the R, but you can choose whichever FCC you want (L, C, or R) to provide your F/D. (Remember on UAL's configuration, an FCC is restricted to EITHER coupling to its autopilot servos OR providing F/D signals).
