I'm curious if the INS heading drift is accurate or currently still bugged. Regardless of human RIO or Jester it is common to find the heading error reaches a maximum of approximately 20° within about 60 seconds of any pitch or roll deviation greater than 0°.

 

Perhaps real tomcat crews had to deal with such inaccuracies, but as a commercial pilot who has navigated some inhospitable terrain, I would say that such a navigational error with such a rapid and continuous onset would be untenable as a navigational source. I would rather use my magnetic compass than such a system. Flying in IMC on instruments would be (is) completely unreliable and dangerous with this sort of error.

 

Is there something I'm configuring wrong? I've tried every switch on the compass panel to no avail (I don't believe those are completely implemented yet?) as well. In coming up on 1.5 years of flying the DCS: F-14B I've never found a solution to this constant problem.

Do you mean the heading is subject to major changes after take-off from the CV?

 

In the vicinity of the CV there will be some magnetic disturbance on the AHRS.

 

Apart from this, I unfortunately cannot answer your question as I am puzzled myself. But maybe I can connect your question with some things I noticed:

 

I did notice the heading is not accurate most of the time, wether one is close to the CV or not. And I do notice on the Compass control panel there's a desync between the AHRS gyro and magnetic azimuth. I can see the AHRS heading is wrong when I compare with the one shown for my auircraft on the F10 map.

Nah, I'm aware of the carrier magnetic field. Just fly away from the carrier and enter a turn of about 30°. The heading error will reach a large deviation rather quickly in my experience.

 

For reference the F10 map is true heading not magnetic heading. You have to subtract/add the magnetic variation to find what DCS is saying your magnetic heading is (which is the actual heading used by pilots and indicated by instruments in the jet).

I'm seeing this too. Immediately after a supercarrier takeoff the compass sync goes full deflection left andI'm about 40 degrees out. No other warnings or indications. Very frustrating! Happening everytime on OCG through the inferno server from cold start

Ok on re-reading the manual and thinking it through there is no issue here. To resync the AHRS there must be no acceleration - so level flight, at steady speed. Pressing the adjustment knob in for ~15 seconds brings everything back into alignment.

 

I don't remember this ever being an issue before the supercarrier though?
