Surface Deice no switch movement using L:var_SurfaceDeiceSwitch
-
The L:var_SurfaceDeiceSwitch does the job, the deice surface works as expected, but there is no visual switch movement in the cockpit when L:VAR value changes.
Is there another parameter to be changed that activates the switch movement?

From another post today:
I see the issue with the airframe deicing switch. That's something easy I will fix in the first update. In the meantime, if you also set L:var_airframeDeiceMode along with L:var_SurfaceDeiceSwitch, the switch will move with your setting.

@Black-Square thanks for the quick response.
This plane is fantastic! Congratulations! -
I was having the same issue so thanks for this post. I am still trying to understand the deice. It seems if the 3way toggle switch is lifted up it puts it in auto mode yet the toggle switch does not stay up and returns to center?! Pushing down does a manual one time trigger is what I get. If all of this is correct then how do you turn off the automatic wing boots?

From the POH:
Deice boots on the wing and empennage leading edges are
inflated by the two engine-driven pressure pumps. A
venturi, operated from the pressure pumps, supplies
vacuum for boot hold down at all times except during the
inflation mode. Through an electric timer,
solenoid-operated control valves cause all the boots to be
inflated simultaneously. The timer is controlled by a
three-position switch: SURFACE ONE CYCLE, and
MANUAL with off position centered. This switch is located
on the left sub panel. ONE CYCLE and MANUAL switch
positions are momentary. A gage is provided to indicate
system pressure. Momentary engagement of the ONE
CYCLE position will cause the boots to inflate for five to
eight seconds, then deflate to the vacuum hold-down
condition. The MANUAL position will inflate the boots
only as long as the switch is held in engagement; when the
switch is released, the boots deflate.This might sound a bit strange, like there is a three position switch to accomplish what you could do by holding down the switch for a few seconds. I haven't confirmed this with any Duke historians, but I suspect this was an unintentional "feature" held over from some other aircraft or system. Many other aircraft have multiple deicing zones. The TBM for example, has inboard wing boots, outboard wing boots, and tail surface boots. In those aircraft, manual mode will trigger all areas at once, in case the timing system fails. Automatic mode will inflate each section separately for a few seconds each. Inflating all at once can not as effective at removing ice, since it requires more instrument air pressure, which is simulated in my other aircraft. Lastly, automatic deicing boot actuation is a very rare feature in general aviation aircraft. You will have to wait for my Starship to see that feature :)
I hope that helps satisfy your curiosity!

Thats great info..thanks. I actually have both manuals printed out but with this plane, I still havent done my 1st official flight and it wont be until after all the hardware is assigned and I have the air manager gauges installed that I will finally be able to do a proper checklist flight and study up on all the systems.
Theres a learning curve of both whats modeled and how to assign things so I am kinda doing things a bit backwards of trial and error and then turning my focus on flying by the numbers with a checklist etc. But I'm having a great time discovering all these birds offer.

Hey, that just means you're flying like the real pilot that you are! I'm not going to fault anyone for having fun with flight simulator, but neither of us would choose to be PIC of an airplane that we had not fully acquainted ourselves with on the ground and in the literature first. It actually delights me to hear that you're taking the aircraft so seriously, because that's how it was designed to be treated.
