Alternate air control lever not moving
-
Hi there,
I use the Honeycomb Throttle quadrant. Now i anti-ice mapped to a switch on the throttle quadrant. Do you mean there is another bind for the alternate air control lever?@Pilottom The Alternate Air lever in this aircraft is the same as Carb Heat, and it is controlled by the ANTI-ICE ON/OFF/TOGGLE commands, or by pressing [H] on the keyboard.
-
ANTI-ICE ON/OFF/TOGGLE commands doesn't work for me.
I even tried to find the related LVARs with AxisAndOhs - nothing works to move the Alternate Air lever :(
I can only operate it with the mouse.@Steku same here. I had everything working just fine prior to UP5, now Alt Air LVAR does not work anymore. Same for the air flow controls.

@anderson Was it working before SU5? What function you used to assign the alternate air (carb. heat) to the physical button?
I hoped that 0.9.0 update will fix this - unfortunatelly - the issue is still present in 0.9.0.
The:
ANTI_ICE_SET (0,1)
when assigned produces sounds of moving the Alternate Air lever, but the lever in the cockpit is not moving and I can't see any impact on engine RPM or mainfold pressure.
Even operatin the lever by the mouse (the Alt. Air. lever moving then) has no effect on the engine. Should It be like that? I have no experience with constant speed prop., in simple plane with fixed prop the RPM drops when carb. heat is enabled. -

I have opened a ticket.

Having the exact same issue. This was most definitely working before SU5, as I had assigned buttons via SPAD.next to ANTI_ICE_SET_ENG1, alternating between 0 and 1. Now the exact same command does update relevant simvars in the background and even generating the button sounds, but the button animation itself no longer works. MSFS cockpit is set to legacy mode.
Hoping that @anderson's ticket has a happy ending.

Turning alternate air ON does bypasses the air filter and provides heated air to the engine intake manifold, but because this engine is fuel injected, and has a constant speed prop, you won't see any change in RPM like you would with a simple carburated engine with a fixed pitch prop.

@retiredman93231 Is there any (noticeable) effect on manifold pressure and/or EGT?

@retiredman93231 Is there any (noticeable) effect on manifold pressure and/or EGT?
@corvus5624 No, not that I am aware of. The unfiltered heated air is not really hot enough to affect the EGT. It might reduce the manifold pressure slightly, but not enough to really notice.

@retiredman93231 Using hot (less dense) air should in principle reduce engine power, as there is less oxygen in the cylinder. I was wondering if this had any effect on the engine parameters. I think it should have, but perhaps it is simply not modeled?

@corvus5624 You are correct, but the RPM won't change regardless, because it is being maintained by the constant speed prop.

@derek Thanks a lot, ticket submitted. I'll post an update here to all if anything comes up.

@anderson
We don't release upodates for our products to a timetable. If something is broken and can be fixed, or something can be enhanced or an update to the host game means a change is required, then we will release an update. The regularity of updates bears little relation to the priority of the product. Also, I guess it depends what you mean by priority. For some of our team, the priority is for stuff that we haven't released yet. Others are working on stuff we released some years ago. -
