correct as-is DCS MiG-29A Flight performance and air drag seems weird

It's a known claim but no. Already solved in Ru part of forums with SME and mechanical scheme. There is phisically two positions for flap, and leading edge - leading edge is scheduled independently for optimal performance at all times.

So the third button (Land) positively has no effect or function and is not tied to anything whatsoever?

Are you saying they have reported the issue on the Ru side?

I believe what was meant was that this was already discussed and cleared up on the Ru side. I read the same thing on a separate English forum that there is a misconception among us users about the flap panel, ie. people think its 3 buttons that only do 2 settings versus the reality of it being 3 buttons with 3 different settings as per some Mig-29 manual or documentation (Up, TO Flap + TO Scheduled Slats, LDG + LDG Scheduled Slats rather than what some assumed was just Flaps Up or Down with an unused middle button). 

It's more a comment on how the misconception above has been explained on the Ru side, perhaps worth making a note of this in the manual later down the road as it is both a very relevant system and of course just interesting technical knowledge (if its correct of course)!

Hi, 

takeoff and landing schedule the leading edge flaps differently. 

I would really love clarification for this. Becuase as far as I can tell in my testing, the leading edge flaps are down all the time with both settings. And nothing I could do could make them go up in “takeoff” flaps. And the LEF only have two settings, down or up.

Perfect, thanks

Happy to try and help.

The G manual says

- maneuvering LEFs come down whenever necessary (AoA greater 8.7° and M less than 0.8 {+/-} and retracting when above said Mach or below 7° AoA)

- LEF come down with flaps selected down

- LEF come down with gear selected down (gear down overrides flap up)

There's no mention of different LEF schedules and it just mentions one UP and two DOWN buttons.
"Pushing either DOWN button extends all flaps. Pushing the UP button retracts flaps and LEF, provided gear is up."

Or the aero manual.

So it is three buttons for two functions.
And as the flaps are blown up by airloads, they could have just left out the entire box and tie them to the gear-handle

It's soldered to the same cable as second button. Pilot in Ru forums said you can normally use either button but for consistency of procedures everybody agreed to use button 2 both for takeoff and landing. The block is re-used from MiG-23 where takeoff and landing settings were indeed different.

No they don't. See the following for a description of the proper operation.

If this is the case, then we really need this to be cleared up in the module's manual, as I've seen different takes from within the forums which are causing confusion. I understand the manual is probably a low priority at the moment but if there is a good clear source on how the system works I think we'd all love to have it even just marked as a special note where the panel is described, at least for the time being. It would greatly help those of us with lesser knowledge of the aircraft to study it and learn it more correctly!

@NineLine Hate to bother you with something that I can probably do, however, I don't know how to mark or unmark my comment as a solution, and with the added info above that would make my understanding of previous comments incorrect. Is there anyway to "unmark" my comment as a solution?
