People are reporting that in 1.05 the INS doesn't drift. In fact, it does. HOWEVER, upon entering any new waypoints, the INS POS is magically corrected to the aircraft actual position. See how all 3 INS units, with POS mode selected, initially show different positions after arrival at the gate, but then, upon entering the correct position into WPT 1, the position values all update magically.

Noted for the team, thank you

I'm guessing there probably wasn't enough time for this to make it into the current patch, am I correct? Or should I put this to the test?

I'm guessing this line: "FIXED INS cannot check drift results post flight in INS due to wp parsing error" addresses it. I can only check it once I get back home.

Should be fixed in 1.0.6 but please check and let us know. The issue was already identified before it was reported here :)

Something is still going on. It's a bit hard to determine what the mechanism is. I just did a Seattle to Boston flight. Nearly 6 hours in the air. During the flight, I updated INS postions 1 & 2 as I passed over VORs. I did NOT update INS 3 during the entire flight.

However, upon arrival, INS 3 showed less than a mile of drift, whilst INS 1 & 2 showed 0.4nm and 3.1nm of drift respectively. (You can see this in screenshot 1)

In screenshots 2 &3, you can see the sensed position and actual position of INS 3.

Although the position is NOT identical to the real position, it does not seem quite right that it drifted so little. It still seems like it's getting a bit of a correction from some operation during flight.

I think this needs to be marked as unsolved again, and investigated a little more. Something still isn't right.

Can it be that INS 3 coincidentally drifted away and then back? Resulting in such good accuracy? Did you do more than one flight?

@Joshua Green If you can, at the end of the flight look up these variables in dev mode - Tools > Behaviours > Variables tab > uncheck "Only show variables..." > search for "drift" :

Include your OFP as well, for devs to investigate further.

Thanks!
