Are slats shy ?

[Crumpp]

I just mean that partial deployment is a neat trick, but who'd ever think about it in combat? And would there ever be a need to conscientiously try to get a partial deployment?

I agree. The point being that the slats work as required AND if they are correctly modeled, the pilot can precisely control their deployment.

It is a function check not a combat tactic.

It's hard to ctrl the amplitude of the slats opening.

Once the slats start to deploy, the gap btw the slat and the LE (leading edge) is the path of the accelerated flow that will impart the equilibrium tending to accelerate any tendency either of opening or closing.

It's hard to ctrl the amplitude of the slats opening.

I never had any trouble, although what you are saying makes sense. It is however balanced by the weight of the aircraft such that the slat only open as required.

TomcatViP,

To clarify..

If you compare the initial opening of the slats and controlling them from the open position, you are correct.

The initial opening is much harder in comparison. It is still controllable but the level of skill required is much higher.

[TomcatViP]

Yes that's what I mean.

Never had to fly with slats until now so it is just my view of how it shld works.

Note = Modern slats on fighters are power ctrled so we can't make any comparison. Tht's why your vid is interesting to watch.

The current il2CoD bf-109 flight model files include the following entry:

LeadingEdgeSlats Mechanical Automatic Move 0.1 sec ResponseRange 15.0 to 15.01 deg

(personal note: when the BF109E stands on the ground, the AoA is 16 deg.)

Following the entry, the slats should function manually and/or automatically.

Looking at the current 15.0 to 15.01 deg AoA, the flaps should not work seriously.

Happy landings

For me it only means that they were not satisfied with the result and blocked it without cancelling the code (for a latter revue ?)

Nice found Varra - a bit scary but nice

Slat operation (or lack of early enough operation) has been snagged with the devs a while a go. That find in the FM probably explains why we are seeing what we are.

i dunno about slats,but sluts sure aren't................

I made an offline test with an E4 today (long time I did not hve tried) and the slats seems to function on that model. I was able to turn 360 with the slats opened.

The E4 is also much easier to handle in high G moves. It might be that the last patch has introduced some significant changes.

Varra in what plane's FM did you found those lines of Codes ?
