ÅTERSTART pushbutton not usable?

[TOViper]

Hello!

 

is it just me :dunno: , or is the ÅTERSTART pushbutton not usable?

Regarding the ermergency checklist for "engine flameout" this pushbutton must be depressed for 2 seconds (just in case the engine doesn't come online on its own).

If I try to depress the pushbutton (e.g. via the mouse), the click just moves the throttle lever, no matter if the throttle lever is near this button or not.

 

I often managed to restart the engine via the START SWITCH, so its not a big issue for me, but indeed would be interesting to know.

 

Thanks for any info on this!

Haven't had any luck with it either

I have had the same experience. Starting using the normal start switch works, but "återstart" only moves the throttle to high pressure fuel valve off.

Thanks for the quick answers guys! :thumbup:

 

So let's consider the pushbutton doesn't work.

I wasn't able to find any detailed infos on this pushbutton in the whole Viggen Forum.

Would it be a good idea to write an official bug report or does LNS already know about?

[IonicRipper]

You could but im positive LNS knows about it. Just didnt have time to finish it before the release.

Cobra, is there any news on the implementation of the ATERSTART pb?

Thanks for any infos.

Hi,

 

I just found out that not only does the ATERSTART button close the HP fuel valve, it also prevents further engine restarts even if you unlock the throttle by clicking on it.

 

It seems like after you presed ATERSTART, the fuel valve is permanently shut no matter what you do next. :huh:

IIRC the emergency checklist says to depress it 2 seconds.

Hm ... have you tried it in this way?

When using a computer screen having the power lever in ground or flight idle, the mouse area for the ATERSTART button is the same as for the fuel shut off function of the power lever, thus it might happen that the lever is then put to shut off.

 

Today I did a test, the ATERSTART has no effect, it doesn't re-light the engine, but after pressing it, I was still able to restart the engine with the normal START switch, so the second statement is wrong.

@Zabuzard  Can you confirm that ÅTERSTART pushbutton currently has no function in DCS? If so, I would label the switch in the manual with [no function] ... Thanks!

I believe I've successfully used it for in-air restarts in the past (though always through keybind, not pushing with the mouse)...
Unless I'm completely misremembering.

[Zabuzard]

The button has function, it is not ineffective. However, in most cases in practice, its function is identical with the built-in flame-out detector (automatic engine start mode). If you ceize your engine by flaming it out, that detector will already prepare the air-start, i.e. what the switch would do. Hence it appears that the switch would not do anything by itself, since its function is already covered by that detector in most situations in which players would want to do an air-start.

Thank you for clarification!

Interesting, thank you. I'm wondering in which situations you would need the switch then if there's an automatic system.

Would be great if the manual covered these details as well, I find the current manual a little "thin" on the technical side of things on the Viggen for us nerds.

[TOViper]

In case the automatic flame-out detector isn't working ... ??

[Volator]

Sure, but just because of a system failure, or are there conditions in which the detector is unable to detect a flame-out, that's the point of my question.

[Zabuzard]

Yes, the detector has some conditions and can fail to check it. It mostly triggers when the engine is actually dead (low RPM, flame out, ...) and if TÄNDSYSTEM (ignition system switch) is in AUT(omatic). If thats not the case, you need the air-start switch to prepare the start.

You can also see whether the detector worked or not by the presence of the TÄNDSYST (ignition system) warning light on the right panel. It will illuminate when the detector or the air-start switch prepared the ignition.

[TOViper]

Think I will put this story to the manual with the next update...
