In flight INS alignment

[Steel Jaw]

For some reason I lost my alignment in the air on mission, how can my INS be realigned please?

1. Land
2. Input coordinates of your parking position into WP0
3. Perform a new alignment

Oh thats no good.  No other options from in the air?

Not if you "lost" your alignment.

If you just have accumulated some INS drift, then you can do a nav fix on the HSI page. IIRC the button was labeled "UPDT" and is on the bottom row. This is still WIP though AFAIK.

The INS dumping was definitely not a thing that happened when I actively flew the Hornet. Is this a new feature (simulated failure) or a bug?

Can you describe that? I never heard of "INS dumping"

TACAN fix, GPS IFA (and radar PVU but that's not modeled)

Flip to IFA and if there's GPS it will be fixed in some 10min.

It's when the INS fails entirely or "dumps" the alignment. This is a scenario when an actual in flight alignment may be necessary in most platforms.

And when does this happen? I've never encountered that.

There may be some miscommunication here I'm afraid. INS 'dumping' or actual INS failure is a malfunction that can happen to real aircraft. As I'm not an actual pilot, I've also never encountered that in real life, but there are plenty of first hand accounts of this happening. There's also a very harrowing tale in the Approach magazine about this happening to a Charlie Hornet pilot near the boat at night.

 

This has never happened to me in DCS, but I haven't flown the Hornet in quite a while, which is why I asked if this is a new failure being simulated or a bug or perhaps user error. Hope this cleared up the misunderstanding.

Oh, I see. Yeah, I was exclusively talking about DCS and there aircraft systems don't just stop working for no reason.

And don't forget to set your parking brake before doing the alignment.
