[NO BUG] compass heading unconsistent with dcs heading

The heading displayed by the compass is not the same than displayed on dcs F2 view ( a 40 degrees difference)

Saw this on PG, carrier cold start and human rio

It's the boat. Launch and it will square up.

From the manual:

"Note that you will get erroneous heading readings on a carrier, even if fine align is complete. The heading can deviate up to 20 or 30 degrees, depending on the parking position on the carrier and the carrier’s heading, due to the carrier’s own magnetic field and induced magnetic field. It is important that the flight crew know the carrier’s BRC. The magnetic variation caused by the carrier’s magnetic distortion will go away shortly after take off. This magnetic distortion does not impact the alignment quality."

Ok thanks, I clearly missed that one !:doh:

No worries, the INS is very complex and modeled very accurately to its real part, also in terms of simulating the single parts in the background liky gyros, accelerometers, etc, the effects of earth curvature, drift, proximity to big metalic structures (ships), and much more. it can be a bit confusing at times for sure.
