The issue isn’t that I black out. It’s that I black out with no warning. Ever since the update where ED changed the G effects I’ve had this issues. I’ll be in a constant pull to track a bandit I just merged with and then just black out with very little indication I was pulling to many Gs.

Not the first time in the plane, I've had it sense release day. The issue I'm having is after the new G effect ED added, you get almost no warning before G-loc. my screens only goes slightly grey before I black out now. No close in or any other effects making it very difficult to tell when I'm pulling to many Gs. When I'm in a dogfight I'm not looking at my G meter so this lack of effect makes its difficult in a turn fight to avoid G-loc.

Is anyone else having issues with blacking out instantly while pulling G's? Other platforms like the F-16 have my screen gradually go grey and close in as you I get closer to blacking out but the tomcat only goes slightly grey and then I instantly blackout. I've died to G-loc more now than the enemy. I think we need some more indications your about to black out before it happens.

I’ll try to make a video showing the precision alignment technique I got to work for me. 2.3 km drift in 30 min is at the high end but still close to what the ED advertise drift rate is. It is interesting that some alignment techniques work for some people but not others though. As for the drift of 1.563km in 45 min in jubuttib’s second test that seems pretty good based on EDsh claimed 4km drift rate per hour which seems correct for a 1980 INU. What Direction I’m flying when the drift rate is decreased seems to be dependent on your initial alignment heading.

For anyone else having this alignment issue I have found a working solution although it doesn’t make any sense to me why it works. Do the alignment as stated in the manual with the motors off till you see the flashing INU PERC or INU NORM button signaling the alignment is complete. Do not hit the button to finish the alignment, just start up and get everything else ready to fly like normal. Then once both motors are up to full speed and you have both gens on and producing power, now confirm the alignment buy hitting the flashing button. I’ve tried to three times in a row now and all three times ive had a good alignment throughout the same 10 minute flight test I’ve been doing. This procedure makes zero sense to me why it works but it does. For everyone that keeps complaining about how long the alignment takes, I’ve attached a short video explaining all the the steps in a INU alignment.

I am now convinced there is a serious bug with the INS alignment. I have followed your video exactly and had a good INS alignment once. Then the very next time I started off to the exact same procedure and failed and started drifting at well over 4 km per minute. ill try to make a trk file i can attach but thy keep going over 5mb

I’m not sure what the exact parameters are that cause the light to pop but if you do a normal or a precision alignment the light won’t pop even if you start pulling some hard turns because the The NAV system is using the accelerometer data.

Accelerated alignment and normal alignment use the same procedure for the gyrocompass (figuring out the aircraft heading). It simply uses the last recorded heading which is why you’re required to realign the HSI to the mag compass. They also both spin up the other rings used for determining pitch and roll. Normal alignment also adds the alignment of some accelerometers to sense aircraft motion in the X,Y, and Z axis. I not sure what the Aircraft is using to determine acceleration data when you do a accelerated alignment since the accelerometers are not aligned. My guess is air data and Doppler. That’s why when you start turning hard after doing a accelerated alignment you’ll get a AC nav Calc warning light.

Please do! I hope it’s just something I’m doing wrong.

My results were pretty close to yours when I didn’t confirm the alignment till after both motors were running. Did you use external power during the alignment? edit- disregard I just tried it again without using external power during the alignment and my results are the same with the extreme drift rate.

After doing some more trials with the new INU, I have found that if you follow the manual and do the precision alignment procedure with the engines off you will have a substantial drift that’s correlated to your initial heading used for the alignment and the speed and heading during the aircraft's first movements. I did the tests by doing several 10 minutes flight around some landmarks in Tbilisi and had observe drifts of 91 to 23 km after those flights depending on what the aircrafts heading was during the alignment. I measured the observed drift by just finding the distance between my position and the INU calculated position so it’s not actual drift rate but total INU error. That means the actual drift rate is probably much worse. I then tried the alignment procedures with the engines off but didn’t complete the procedure until after I had the motors on. I then repeated the flight and has a observed INU error of just about 1km. This confirms to me at lest that there is something bugged with the precision alignment. I have not tried this with normal alignment but if I get some time I’ll try to. I do have a few saved track files if anyone would like me to attached them. -Rob

I’m beginning to think there’s a bug with the normal and precision alignment. Whenever I start up with a precision alignment facing south at Kobuleti, the system works fine with no noticeable drift during flight. But if I do the exact same startup procedure facing north, as soon as I start moving the INU starts drifting at a extreme rate. Over 5 Km per minute to the south typically. I get that most people don’t want to do the full alignment but I would like to know how to do the full startup myself including the alignment. I’m not asking for a quick alignment cheat, just for the normal and precision procedure to work. -Rob

I think a cool idea would be to have the option to show to the aircraft with the alignment already done. They already have an option to choose what quality of alignment was accomplished if you spawn in hot. I doubt the real pilots just sit there for 20 minutes before every flight. They probably have the ground crew do the alignment as part of the preflight checks and then show up when it’s done.

It just depends on what kind of mission you want to do and how you like to fly the bird. If you are like me and use lots of target points and data link points then having a good alignment is necessary. Going with the accelerated alignment leads to much quicker INU drift, especially if you are doing a lot of hard turns. You will even see a warning light pop on the overhead when you do anything more than a shallow bank. Normal alignment allows time for the alignment of more than just pitch roll and hdg. The only real difference I can see between normal and precise alignment is precise finds the aircraft heading for you.

I am wondering if anyone has been able to get the normal or precision alignment to work correctly. I’ve been following the steps in the manual but I’m still having issues. I got the accelerated alignment to work just fine but the other methods have a serious drift issue once I start moving. I can get the alignments to complete correctly and have a stable position in the start spot but as soon as I start taxing or flying, the INU starts drifting a few kilometers per minute. The faster I was going the worse the drift. Im assuming it has something to do with measured absolute Inertial velocity because i dont have this issue with the accelerated alignment. Any help would be appreciated. -Rob
