Taimoor Posted December 12, 2020 Share Posted December 12, 2020 Hello C130 professionals! In an E Model Hercules, Flight Director Flag (FD flag) came in view on Co Pilot side PFD on ground during normal checks. Against the defect, all associated LRUs were replaced/swapped with serviceable ones. Even the PFD was swapped with pilot side, yet the flag did not disappear. Continuity of wiring was also double checked and was found SAT. No visible issue was observed yet the flag did not disappear. Autopilot engages without any defect and is working fine. Any ideas as to what might cause this or any previous experience, please do share. Thanks! Quote Link to comment Share on other sites More sharing options...

Record all 6 digits in sequence of both left and right columns of the diagnostics data. Press and hold any 3 active MSP buttons for 2 seconds. The PFD shall display the REPORT MODE. Use the APP Pitch Wheel to select the codes. Munir Abbasi Quote Link to comment Share on other sites More sharing options...
