King Air Autopilot IAS hold

kityatyi

I wonder which MSFS assignment works for the IAS hold function of the King Air's autopilot.

I tried several potential ones but none seems to work. I found that the TOGGLE AUTOPILOT FLIGHT LEVEL CHANGE toggles the King Air's CLIMB function of the autopilot but I want to assign the IAS mode.

Does anyone happen to know the answer, please?

Here is the code from the behaviors XML. Hopefully you are using something like Spad.next, or FSUIPC so you can just copy this code as-is. If you need further help, let me know.

(A:AUTOPILOT FLIGHT LEVEL CHANGE, Bool) if{
	(L:var_iasHoldMode, bool) if{
		(>K:FLIGHT_LEVEL_CHANGE)
		0 (>L:var_iasHoldMode, bool)
	}
	els{
		(A:AIRSPEED INDICATED, knots) (>K:AP_SPD_VAR_SET)
		1 (>L:var_iasHoldMode, bool)
	}
}
els{
	(>K:FLIGHT_LEVEL_CHANGE)
	(A:AIRSPEED INDICATED, knots) (>K:AP_SPD_VAR_SET)
	1 (>L:var_iasHoldMode, bool)
}

Thank you for your kind reply, Nick. I never heard of that SPAD thing, and as for FSUIPC, I do not use it, I used to use it in P3D and FSX.
I assume none of the default bindings work for the IAS hold function of the AP then. No big deal, I will continue "clicking" the button. Slightly cumbersome but it is what it is.

Unfortunately, that is the case. The default control bindings are very limited, so almost all hardware users pair their setup with some 3rd party control binding software with MSFS. Several of them have online repositories of configurations that users have made for almost every aircraft, including mine. If you ever do want to give that a shot, you can often select the cockpit button you wish to create a binding for from a dropdown menu, and you're done.

Thanks for the information! I will have a look, I've seen this SPAD.next name buzzing around in the community for a while so I guess it's something very popular - it would be sheer stagnation on my end not to learn this new tool of the trade. :-)

EDIT: Didn't know it was a payware item. Do I need the "Complete Edition" or will the (cheaper) MSFS/FSX/P3D edition suffice, please?

@kityatyi, the MSFS/FSX/P3D version will be adequate to get you started. There is a 14 day free trial so you can try it out before spending the money for a license.
