Real mode rudder inputs

Are you sure?

To be honest: No. But I think it's reasonably plausible that HUD speed indication and auto hover rely on the same system. :-)

Besides, the link provided by EinsteinEP contains this:

The doppler navigation system is used to determine the speed and angle of drift of the helicopter.

If the above is true, then the Doppler Velocimeter takes longer than the INU?

That does seem a little weird. On the other hand, our INU comes online within seconds. I think I read that the real INU takes several minutes until it's ready (just like I remember it from the F-16 in Falcon). So if INU alignment was properly modeled, we probably wouldn't even know that the Doppler Navigation System also takes a good long while to align/get ready.

Well, true yes. I see the validity in having problems when rushing through things when flying with your buddies. But in this case while we were both trying to ascertain the cause of the problem, there was certainly no implied hurriedness going through the start up procedures and waiting for the INU to align.

 

There were actually quite a few times, after we'd both started our choppers where we were talking over TS for about 5 minutes before taking off.

I concluded your rushing through the startup from watching your uploaded track.

So, auto hover switching off the AP channels also happened 5 or more minutes after startup? Were the engines running at full power and generators on?

Another possible cause could be (though I'm not sure): on heavy maneuvers with full collective, it's possible to run low on power (the rotor RPM warning lights up, Shkval goes dark). After power is restored, it takes a while for the Doppler Navigation System to be ready again. Could this have happened?

From an experienced BS pilot, I'll take this as a reminder to go slower through the procedures. Thanks for taking a look at the track. ;)

Both LH and RH AC SYS GENs were on and the throttles were in auto (page up x2). I could be wrong, but I get the impression the bird needs to be in the air a few minutes before one can simply go into an auto-hover. I found that if I just didn't engage it right away and flew around a few minutes, the auto-hover was not turning off my AP functions.

At the time I wasn't performing any agressive maneuvers or inputting alot of cyclic commands so I'm not sure either. I've since remapped a hat switch to my ap modes for the, 'just in case', which seems to help. Though as I mentioned, giving the heli some time once in the air all seems to be working as it should be.

To be honest: No.

 

...

Yeah, it really is weird. It seems to conflict (per EinstienEP) and if the good 'ole OCD was a dash more severe, it would be causing sleepless nights. I too have read elsewhere that INU alignment isn't modeled realistically.

Still, I like how Viper worded it...

if relevant system is not online then AH will not function

EvilBivol-1 has stated it.

Viper has demonstrated it.

The rest of us can reproduce it.

I just did a little test flight. As soon as I have a HUD airspeed indication, auto hover works. Without airspeed indication, auto hover will disengage the AP channels. So I think it's safe to say that both auto hover and HUD airspeed indication rely on the same system, which would be the Doppler Navigation System.

At this point in time, I would like to change my original answer to: Yes, I am sure (that both auto hover and HUD airspeed indication rely on the same system). :-)

In the Sim, I would say that based on yours, others & my own tests, that your conclusion is rationally correct.

A developer has stated it's the INU. I mean, he was pretty direct in specifying exactly what the problem was & corrective action to avoid it. When he stated he was wrong (later in the same topic), it was the duration of time to wait for INU alignment, not which system did what.

The question here is: Does this reflect modeling in the actual aircraft? I honestly don't know. Others who are certainly a lot more smarter than I who have great working knowledge of these systems apparently agree that it's INU's "job". None argue that it's the DNS that measures ground speed.

So is it that the INU controls the auto-hover in the real-world aircraft but in the sim, it's modeled differently (DNS)? It's starting to seem that way based on the many conflicting answers given...but that could be my own ignorance scrambling to find logic.

It would be nice to get a clear answer & put this to bed.

I'll shake the tree and see what falls out.

Agreed.

Thanks!

Yes indeed. Thank you Viper.

Another auto-hover topic that identifies the DNS as the system that controls auto-hover.

It's the DNS that controls auto hover, in-game and real-world.

Was about to confirm but already addressed - Good.

In furtherance thereto - it takes the DNS 150 seconds from start-up to come 'online' for lack of a better word.......wait the period out and you should have ground-speed indication at lift-off and accordingly will be able to engage auto-hover immediately, altitude restrictions allowing.

That's great to know, thank you guys!

Fantastic.

Thanks guys.
