How do I know that stored INS align is possible?

[darkman222]

As I can save time starting up the F16, how would I know that I can use stored INS align?

I read that it can be set as an option in mission editor. Where is that option?

 

If I fly on a public server I would bring the replay file in the mission editor and check if the slot I select has it set. Then I'd know next time.

At the moment, Stored Heading is always available at mission start. There may be an option for this added later in development like the Harrier has, but it doesn't exist now.

What would be great is if we could cock the jet for a future stored heading alignment in the same session. Right now, If you shut down using the stored heading alignment, and then start the jet back up, the stored heading coordinates revert to where the jet was when you started the mission. So.... What you can't do is fly across the map, shut down, and then fire back up after eating lunch to fly back across the map using a stored heading alignment. It would be nice to see that modeled.

Can't you just enter the new coordinates manually?

No, it won't take them currently on a stored heading alignment. Whatever you type in will be kicked out, and the location where the jet started will be displayed again.

You can re-enter your current position if you do a full INS alignment.

The -1 has a procedure for shutting down the jet where it will be ready for a stored heading alignment the next time you start -- but it doesn't take in DCS. If memory serves me right (which it probably doesn't) -- you are supposed to cock the alignment by going from NAV to Stored Heading for 10 seconds and then to off. I honestly don't remember, but i spent a few attempts doing the checklist procedure from the -1, and DCS always replaces where you should be with where the jet started in the mission.

Not sure if it's a "Bug" or another half-implemented system. I'm holding off on making a bug report until the team starts really working on the avionics.

Thanks, that's good to hear!

How do you use store heading in Viper? In Hornet there is OSB button but I didn't see such a thing in F-16. When I do align INS it always takes 7-8 minutes, I assume it's a full alignment.

You turn the INS mode selector knob to Stored Heading, should take a couple of minutes or so to align (only to 1.0 quality though, compared to 0.6 of a full alignment).

 

Just be careful when setting the mode when done, I always mistakenly right click it once, which puts into the regular ground alignment and if I'm not fast enough I have to do the alignment all over again.

Thx. I found it myself when I jumped into the cockpit right after my last post. Don't know how I missed it before?!

 

I've noticed there is also In Flight Alignment. Does it work the same way as IFA in Hornet, updates itself with GPS data?

AFAIK, nav is what you should use in flight, and it does use GPS corrections.

 

I'm fairly sure IFA in the F-16CM is just for alignment, and you switch it to NAV when done. (I think you have to fly in a straight line for it to work properly, though I'm not sure INS implementation is complete).

+1

 

And IFA actually is implemented as you state.  If you need to re-align in the air, you set the switch to IFA, set/confirm your heading in the DED, and fly straight until aligned, then back to NAV.

That's what I thought, thanks for confirming 

 

It is not like the Hornet where NAV is used for just INS and IFA is used for INS/GPS (INS updated by GPS).

I just flew from Kutaisi to Senaki on standby gains (INS never turned on). I then did a stored heading alignment which completed to status 10 in 1.5 minutes. This should have completely failed I think since heading was way off. I don't know if 20nm is a problem for convergence on the position solution. Looks like stored heading always works even when it shouldn't. This makes "cocking" impossible to test because it works when you do the right procedure but also when you don't.

 

F-16 INS/GPS (I think it's not actually an EGI technically) has coupled and uncoupled modes but the setting for that is buried in the DED menus and not the NAV/IFA switch like the Hornet.

 

If you enter new L/L during a stored heading align you're not doing a stored heading align anymore. Those actions change it to a BATH align.

Yeah, we don't have EGI our jets.

 

I haven't tested in DCS, but in the real jet, you're supposed to be able to do an in flight align on the ground in lieu of cocking and stored heading align, and have it sort it all out for you.  Not sure if that's for the EGI models only though.
