Hey there!I've been searching some code to increase/decrease the angle of the ATT Hold A/P function in a previous post in this forum but found none. Does some one know how to modify the (A:AUTOPILOT PITCH HOLD REF, degrees) and want to share a workable XML code?. Thanks for your replies.Javier

I looked for a solution a while back. I couldn't find any in xml, but did find two discussions with possible ideas;http://forums1.avsim.net/index.php?showtop...p;hl=pitch+holdhttp://forums.flightsim.com/vbfs/showthread.php?t=211296If you find a solution would you post it, please? F-4Js only had Pitch/Roll/Yaw in their AFCS...Don

Hi Don!Oops, sorry but don't understand C, looks like you have to indicate what is what you want to modify before you can modify the parameter, kind of when you want to change the frequency, you got to indicate which radio you want to retuned.Any how V/S can still be use to get the ATT Hold using the same trigonometry used to calculate the FPA, after all a FPA can be translated to a V/S.JavierPS posted a moment before the reply below, I tought that it doesn't but seems like ATT Hold works.

hi,don't have code here, but these work:SYNC_FLIGHT_DIRECTOR_PITCHand thenAP_PITCH_REF_INC_DNAP_PITCH_REF_INC_UPor something like thattested it years ago, but don't use it anymorewhen time i shalll try to findjan

Thanks!! I never would have found that. I thought the AP_PITCH_REF_INC u/d were for reference on the Attitude gauge!...Don

hi,It was:(>K:AP_PITCH_REF_SELECT) (>K:SYNC_FLIGHT_DIRECTOR_PITCH)and hereafter(>K:AP_PITCH_REF_INC_DN)and(>K:AP_PITCH_REF_INC_UP)does change the pitch attitude.jan

Hi!Kind of weird you got to indicate you want to change the pitch angle prior to any modification, but well, I suppose it is another kind of parameter. I was thinking in using V/S to make the aircraft climb/dive until the required pitch angle is reached then sync and hold ATT.Don, Jan thanks for taking the time.Javier

This is what xml I got to work this AM. Just a quick test was OK.

<?xml version="1.0" encoding="utf-8"?><Gauge Name="Pitch Hold Toggle" Version="1.0">  <Element>	<Select>	  <Value>(L:PitchHoldDCB, number)</Value>	  <Case Value="0">		<Image Name="F4_AFCS_Switch_Off.bmp" Luminous="no" ImageSizes="22,34" />	  </Case>	  <Case Value="1">		<Image Name="F4_AFCS_Switch_On.bmp" Luminous="no" ImageSizes="22,34" />	  </Case>	</Select>  </Element>  <Mouse>	<Tooltip>%Pitch Hold</Tooltip>	<Area Left="0" Right="22" Top="0" Bottom="10">	  <Cursor Type="Hand" />	  <Click>1 (>L:PitchHoldDCB, number)  (>K:AUTOPILOT_ON)		  (>K:SYNC_FLIGHT_DIRECTOR_PITCH)	  (>K:AP_PITCH_REF_SELECT)	  </Click>	</Area>	<Area Left="0" Right="22" Top="10" Bottom="20">	  <Cursor Type="Hand" />	  <Click>0 (>L:PitchHoldDCB, number)  (>K:AUTOPILOT_OFF)</Click>	</Area>	<Area Left="0" Right="11" Top="20" Bottom="34">	  <Cursor Type="DownArrow" />	  <Click Event="AP_PITCH_REF_INC_DN" />	</Area>	<Area Left="12" Right="22" Top="20" Bottom="34">	  <Cursor Type="UpArrow" />	  <Click Event="AP_PITCH_REF_INC_UP" />	</Area>  </Mouse></Gauge>

I had to fool around with the AP on/off for stand alone gauge, but if you engage AP Alt Hold it switches off. I still need to work on the visible switch change so it turns off with AP and Alt hold also...DonBTW thanks to all for their ideas/input
