Did Ju 52 trim/flaps wheel have "stops"?

[dbuile]

I can't recall if this in-game behavior was always there, or is only after Normandy release:  when jointly moving flaps/stab, and the flaps reach their full in position, movement stops at the point: that is, the animation for the trim wheel stops, and no change to the stabilizer occurs in that given direction.  However, the game still "registers" if additional input was given by the user, so that:  once flaps and trim are de-coupled, all that "stored up" input is applied to the stabilizer, including the animation of the trim wheel, although the user is not currently "moving" the wheel.

 

So, the question is:  in a real Ju 52, with trim/flaps coupled, once the flaps reach a fully in position, is the crew able to move the trim wheel, or does it stop?

The answer to your question should be YES, but I'll try it myself when next to the sim tonight :-), because on Dev blog #141 you can read:

"However, it is possible to unlink these controls and adjust the stabilizer without touching the flaps"

 

Yet, as per the same Dev blog, beware that:

"It is important to note that it is possible to render the system inoperable by deviating from this order so it won't be able to control either the stabilizer or the flaps. For example, if pilot the pitches the stabilizer all the way up with flaps retracted and then engages the link, the flywheel will be blocked because the fully turned down stabilizer and fully retracted flaps won't allow it to turn either way."

 

I found : Junkers Ju-52 Manuals | Page 3 | Aircraft of World War II - WW2Aircraft.net Forums

 

which actually also refers: Dev blog #141 / IL-2 Sturmovik: Great Battles (il2sturmovik.com) 

 

from where we get:

 

"The second interesting feature of this aircraft is that the flaps are operated using the same handle as the adjustable stabilizer. However, it is possible to unlink these controls and adjust the stabilizer without touching the flaps. There is a stabilizer control flywheel in the pilot’s cabin that is always linked mechanically to the stabilizer and the additional flaps link handle that connects the flaps to the same flywheel. Therefore, pilot can either use this flywheel to control only the stabilizer or the stabilizer and the flaps simultaneously."

 

And, last but not least:

Thanks, Cargini!  The links you include provide an answer:   

 

" the flywheel will be blocked because the fully turned down stabilizer and fully retracted flaps won't allow it to turn either way."

 

So, there's a physical stop.  I think this means the in-game behavior is a bug.  Ie, when the stab/flaps are LINKED, and either reach their limit of movement, any further input to the other item should be *discarded*.  Currently, the game stops the visual input, but "saves up" the button clicks to the stabilizer without applying them.  Then when the user UNLINKS the surfaces, the "saved up" inputs are mistakenly applied to the stabilizer.   Based on the real-life description, that cannot happen.    

 

I have not tested whether this happens to the flaps when the stabilizer reaches its limit.  

 

P.S.  thinking this through, I imagine this issue CANNOT be effectively avoided if the stabilizer is mapped to an axis.  It could be addressed if mapped to button presses, though might not be worth the effort...  as a player, I just have to turn on techno chat and stop pressing when linked stab/flaps reach, for example,  50% / 0%

 

Oh, actually, the game already doesn't apply axis differences until they "change" again... so, perhaps you only get the discrepancy after you've unlinked, and LATER touch the stabilizer axis.

 

Anyways, I shouldn't call it a "bug"... dev might be fully aware of the inaccurate behavior, but say it's currently functioning "as expected" based on game design limitations.

Exactly ?
