Ty Klinefelter Posted March 5, 2020 Share Posted March 5, 2020 Not a C-130 problem, a C-12 compass problem on a CASA 212. I am a AF retiree working on an Army contract at Ft Bragg. Worked C-130 Comm/Nav and GAC for 19 years. We defined a problem with our C-12 compass system. Compasses are not synching. Still have a heading flag on the HSI when the needle is centered on the compass controller. At an aircraft heading of 0 degrees, the heading flag on the HSI does not go out until the controller is adjusted to 347 degrees. thank you in advance.

Jcapsparkchaser Posted March 8, 2020 Share Posted March 8, 2020 Tyrus have you done a check of the flux valve? sounds like 1 is lagging? We didnt have a rose at the Grove so everytime I changesd a flux valve, I made sure I scribed the old and new with a sharp point (ETCH) then have aircraft towed N-S-E-W and check how both sides sync. I also had Bear Kramer fly FCF and check it over the Grove. Good Luck Ty! I know you'll fix it! I know it was a pain working the C-12 when we went to Desert in 90-91 cause we had 5 WC-130s (Es) from Kessler with us at Thumb Rat! Quote Link to comment Share on other sites More sharing options...
