They aren't spring loaded to any position (no springs) but they do operate automatically and independently. On the ground (three point attitude) you can push them in and they will stay up or you can pull them down and they'll stay down, try it the next time you're in a museum displaying a 109 (and ready to leave). I've always thought it might have been a good idea to reduce the deployment angle of the slats and then run a small cable between them to make them deploy/retract together, but then they wouldn't have been operating as efficiently ...

No springs at all. Its just there on roller slide or, in case of before the late 109F, a swing arm. The slats are simply sucked out into their open position by the airstream pressure due to their aerodynamic form.

You can actually push them in or pull them out with a finger on the ground.

That depends how hard the pilot yanks on the stick.

(played with slats on CAF 109)

So it looks that even 109 slats in COD are screw.

1C really have much work to do in near all areas of these game :(

The slats keys are for the Tiger Moth which had manually adjustable ones ;)


From what i've seen when flying the 109 the slats deploy all right, just not as much forward as in IL2.
I don't know if this has any effect on the actual FM or if it's just a graphical glitch and we get the full benefit of having them.

In any case, i wouldn't draw any conclusions yet just because they seem a bit "stiff".

Interesting stuff. Thanks for enlightening me guys.

I think BF109 can deploy manually the slats. Anyway it's clear that they are not modeled in the flight model.

And how did you get that idea???
The slats are there!
They deploy automatically!
I can't test it in the FM as there is no option to have them not engaging in the right situation. ;-D

my slats seem to work fine :)

Yes, they are there, but there is no feedback in the Flight Model. The sltas were a really smart way to improve the low speed or near stall handling capacities of a plane. Even in the historical books they talk very good things about them. The BF109E3 response in CoD is like a plane without slats. Like FW190 or P51 in IL2.
