CAWS AP DISENG should only last 30s fix (for Bert's mod)

I found this description in pilatus's manual (7-34-8):

Quote

A/P DISENG caution is delayed 3 seconds in order to prevent aural warning conflict with the autopilot system. A/P DISENG caution goes off after 30 seconds.

So I dig in the xml and RPN Scripting (and mostly by coping code from other place), to make it work like this.

in GAUGEPC12\Gauge_Anum_DOWN_PC12V4.xml:

under:

        <Image id="Gauge_Anum_PC12_BG" Name="Gauge_Anum_PC12_BGNOP">
            <Transparent>True</Transparent>
        </Image>

Add: (shold NOT included in <image>, I think it should start like line15 or so)

 		<Update>
			<Script>
(A:AUTOPILOT MASTER,BOOL) 0 !=
if{
	0 (>L:AUTOPILOT_MASTER_TIMER,number)
}
els{
	(L:AUTOPILOT_MASTER_TIMER,number) ++ (>L:AUTOPILOT_MASTER_TIMER,number)
}		
             </Script>
		</Update>

And then, find     <Element id="Gauge_Anum_PC12_AP_DISENG">  ,edit the whole <Element> entry into

		 <Element id="Gauge_Anum_PC12_AP_DISENG">
            <FloatPosition>0.000,0.000</FloatPosition>
            <Visibility>(A:AUTOPILOT MASTER,BOOL) 0 == and (L:AUTOPILOT_MASTER_TIMER,number) 0 &gt; (L:AUTOPILOT_MASTER_TIMER,number) 18 6 * &gt; (L:AUTOPILOT_MASTER_TIMER,number) 18 66 * &lt; and</Visibility>  
            <Image id="Image" Name="Gauge_Anum_PC12_AP_DISENG.bmp">
               <Transparent>True</Transparent>
            </Image>
         </Element>		

Also, to synchronize the Master Caution Light. go to GAUGEPC12\Gauge_Anum_MASTER_CAUTIONV4.xml ,find <!-- TEST8_MASTER_CAUTION -->

Edit them into

(A:AUTOPILOT MASTER,BOOL) 0 == 
(L:AUTOPILOT_MASTER_TIMER,number) 0 > (L:AUTOPILOT_MASTER_TIMER,number) 18 6 * > (L:AUTOPILOT_MASTER_TIMER,number) 18 66 * < and and
(L:PUSH_TEST8_MASTER_CAUTION,number) 0 == and
if{  1 (>L:TEST8_MASTER_CAUTION,number) }	
els{ 0 (>L:TEST8_MASTER_CAUTION,number) }

(A:AUTOPILOT MASTER,BOOL) 0 == 
(L:AUTOPILOT_MASTER_TIMER,number) 0 > (L:AUTOPILOT_MASTER_TIMER,number) 18 6 * > (L:AUTOPILOT_MASTER_TIMER,number) 18 66 * < and and !
if{ 0 (>L:PUSH_TEST8_MASTER_CAUTION,number) }

Now, when you (or something else*) disengage autopilot, the A/P DISENG light on CAWS along with Master Caution should only illuminate after 3 seconds of delay, and goes off 30 seconds later (with out this mod, the MC will go off 30s later in Bert's mod, that's where I got the code)

   (*Note, the AP should be disengaged when using pitch trim switch, it's not in the gaugue's logic, but I get it covered by assign both trim switch to autopilot_off control in FSUIPC.)

And don't ask why and how it works, I don't know, the RPN scripting drives me crazy....
