What is the relationship between % and ° for the stabilizer

[bycomet]

I am learning to fly BF109F4, in the specification I note that the stabilizer(or called elevator trim?) should be set to +1° for taking off and -4° ~ -5° for landing.

But in game, when I adjust stabilizer, it will give a range from -100% to 100%.

So how can I match these two means of reading, what percentage is the equivalent of +1° and what is  -4° ~ -5°?

When you say -100% to 100% I assume you are reading the tech tips in the GUI?  To see the trim setting in degrees you need to look at the actual trim indicator in the cockpit: it is on your lower left next to the big wheels that change flap and trim setting. When you press the key and see the trim wheel move you will notice the number in the cut out hole changing.

Cheers.

% is simply the axis of the game. What you are looking at for those degree values is this (using a DCS K4 screenshot here because I don't have access to the game where I am right now):

Those should indicate the stab setting in °

Understood, thanks all. It's the first time I can land it steady, so excited.

Nope.. you were correct the first time... It's actually "stabilizer-trim".

When you use trim on the 109 and 190, the whole h-stab pivots up or down - there are no in-flight adjustable trim-tabs on the elevator itself (or on any other control surfaces) of these two planes.

That's why the label you'll see next to the flap- and trim-wheels on some 109 variants says "Flosse" - literally meaning "flipper" or "fin", but in this case it means horizontal stabilizer. Elevator would be "Höhenruder" (literally: "altitude/height rudder") while the horizontal stabilizer is called "Höhenflosse" ("altitude/height fin").

 

Good job on your landing BTW...

This is only valid for 190, Bf 109 has a fixed horizontal stabilizer.

No, it does not. You can actually see that in game, the stab angle difference between nose down and nose up trim is large enough. And of course you can check drawings/manuals to verify.

What JtD said.

 

Also: Check this pic. Hidden as spoiler for obvious reasons...

You're right, but starting with F2 the stabilizer is fixed, see the photo.

 

No, it's not. That's a fairing, not a fixation. See any manual.

I think you should remove your picture man..

How many times do I have to repeat myself. 109 and 190s stabiliser trim moves whole stab. It is the very same tech that modern jets use as elevator or yaw controls since when you move the whole surface you do not suffer from comptessibility.

 

[II/JG17_HerrMurf]

Yep, put it in a spoiler tab or a Mod is gonna remove it anyway. 

 

 bycomet, what are your issues on landing? I regularly stick landings in combat trim configuration (mostly because I’m lazy).

[SvAF/F16_Goblin]

From the K4 manual, the tailplane control rod.

Ok, I deleted the photo, but the plane is exposed in a museum in Canada, and the discussion is about the technique not ideology.

You can either blur the tail marking or put the whole pic behind a spoiler tag. Deleting is not absolutely necessary. Rulz is rulz.

Seems obvious to me and everybody, don't worry !

The problem is that the thread can get closed if it contains such a photo.

 

As said by Murf, no need to delete though, just paint it or make it a spoiler.

Happy new year fellas !

[YR-DAN55]

Sascha, you are right  the system acts on the stabilizer.

We know, but there are rules (well, to be more precise, there are some laws in some countries against swastikas, and this forum can't make an exception)

You can post some, but under a spoiler, like 1Sascha did in his post

  I did not know how to "hide" the photo, I deleted it, closed case.

A good year
