- Nav Source Selector (p24) now fully drives the PFD: shared brg1/brg2 state (App ↔ RMU ↔ PFD). RMU has both pointer knobs — ◯ blue (OFF/VOR1/ADF1/FMS1) and ◇ white (OFF/VOR2/ADF2/FMS2). The PFD resolves each to a magnetic bearing (VOR bearing, ADF relative+heading, GPS bearing) and the HSI legend reflects the selected sources. - PFD FMA / AFCS mode annunciation bar across the top (lateral · AP/FD · vertical) reading the per-mode *_status datarefs — active green, armed white, matching the real Primus PFD.
