Revert cowl flaps to auto from manual - radiator flaps

[Bucic]

How it's done? There's no "back to auto" keyboard binding in-game. Also, wasn't "cowl flaps manually fully open" part of the Take Off procedure around 2015?

I believe cranking them down to minimum is supposed to re-enable the auto mode.

As for the pdf manual, it's an outdated hodgepodge of often confusing or contradicting data so I wouldn't put too much attention to procedures written in it. I stopped tinkering with manual radiator mode long ago. In typical combat scenarios it wasn't really needed with old cooling system simulation and isn't needed (in my opinion) with the new one.

There is no auto mode. Theyre always in auto mode. You only set the thermostat to have them open to a certain temperature really.

You can observe this, by crusing at normal temps/rpm and then manipulating the knob.

The gills will close/open briefly but then go back to the position at which they give the minimum temperature that is ideal to cool the engine, if that makes sense?

So eg if the thermostat is set to cool up to 120, your temps are 100, and you crank them open, they will open but revert to old position as its the "ideal" for a certain threshold.
You of course can over ride this but crankin them more open or closed, but again, theyre always on auto really.

The minimum will close them totally and let them there, which will fry your engine in seconds. 

I use my virpil throttles ring decoder to set the temps and just count the inputs back and forth really.

I agree. I'm only asking for the purpose of combat emergency where the engine starts to misbehave right after I take hits. I'd crank them open, climb, heading home and only then I would like to slowly "get back to auto" and observe the engine parameters.

That non-feathering propeller is a bummer since dora has a high aspect ratio wings and would glide pretty far.

So it would seem the knob doesn't command the position but rather the thermostat setting. So:

fully closed position is 1000 deg Celsius

fully open is [still around 100 deg Celsius with flaps automatically closing to whatever position gives 100 deg Celsius]

 

How about the takeoff procedure? Am I dreaming this up? There was never anything about radiator flaps in the DCS takeoff procedure?

[Doughguy]

I never operate them on the ground. They open themselves if you reach a temp of about 80 / 90 degrees.

If your engine seized you can close them anyway, they might be closed by now anyway for mechanical reasons or stuck.

The cowlflaps are a bit weird and poorly explained but thats about how they work.

I dont really touch them only i combat i tend to give the engine a quick cool down between fights. i just open them a bit and then revert back

There is some speed penalty with opened cowls tho.

You revert back by the feel of your physical controls. I think I can only only achieve that by diving down in the cockpit. Just stating the obvious

[Doughguy]

oh well.. i had them on the keyboard before. yea its tedious, but again, you dont really need to manipulate them

I'm going to try this out:

My procedure to get them back to auto:

-throttle back to low power setting (2000 - 2200 rpm)

-close radiator flaps completely -> now it's automatic again

 

Works all the time for me, I don't know if this is the right real life procedure...

Some pilots never touched the radiator control, others used manual control to slow down in combat situations...

 

Also found anothr thread.

 

 

 

Recent bug being hunted down

 

 

More findings

 

 

 

 

Even more

 

I guess a shoddy manual does translate into higher post count.

I never touch the cowl flaps and also never had any problems with the auto settings. Also never experienced engine problems with the Dora (except for being hit there, of course). But I use the MW50 very, very seldom and then only for seconds. No reason, the Dora is the fastest bird in WWII DCS anyhow.

Okay, today I experienced an engine failure without reason. 

[Doughguy]

Just had to jinx it

Same here after the update. Grab short track files gents!
