There's an excellent post on this forum for calculating percentage complete. After scratching my head figuring out why this wouldn't work for me, I realized that xacars, and subsequently kacars as well, does not calculate distance remaining. Which explains why this data never shows up on my map. I modifed ACARS.PHP to manually calculate the distance remaining no matter what client you're using. I've only tested this with xacars client. I'll also post the percentage complete code here as well as I've modified that slightly.

ASCARS.PHP located in core/modules/ACARS

For the animated percentage bar, place the three gif's (bar.gif, bg_cover.gif and bg_bar.gif) in your lib/images directory. Also, keep in mind I'm not using the variable flight.distremaining on the TPL's (templates). I'm using <%=flight.distremain%>.

If anyone finds this information useful, let me know.

I have a slight problem when using this. I already use dd, dt and dl in my css, and it is interfering with my registration and log-in pages. The forms on those pages are showing the images from your css code.

width:200px;        
height:25px;        
background:url(/lib/images/bg_cover.gif) 
repeat-x;        
top:0;

}

My css that controls the forms on registration and log-in

dl { position: relative; width: 730px; z-index: 100; clear: both; }

dt { clear: both; float: left; width: 180px; padding: 0px 0 2px 0; text-align: left; font-size: 12px; font-weight: bold; }

dd { float: left; width: 520px; margin: 0 0 8px 0; padding-left: 6px; font-size: 12px; }

dd button { }

dd p { margin-top: 0px; }

dd input { width: 300px; padding: 3px; margin-bottom: 3px; z-index: 500; }

How can I solve this so they aren't conflicting each other?

I have a slight problem when using this. I already use dd, dt and dl in my css, and it is interfering with my registration and log-in pages. The forms on those pages are showing the images from your css code.

You can rename them in the css and your template file.. Try this:

percentdd{
width:216px;
height:41px;
background:url(/lib/images/bg_bar.gif) no-repeat 0 0;
position:relative;
}
percentdd span{
position:absolute;
display:block;
width:200px;
height:25px;
background:url(/lib/images/bar.gif) no-repeat 0 0;
top:8px;
left:8px;
overflow:hidden;
text-indent:-8000px;
}
percentdd em{
position:absolute;
display:block;
width:200px;
height:25px;
background:url(/lib/images/bg_cover.gif) repeat-x;
top:0;
}

And change your ascars.map file to:

<percentdd>
		<span><%=flight.percomplete%>%<em style="left:<%=flight.percomplete * 2%>px"><%=flight.percomplete%>%"></em><%=flight.percomplete%>%</span>
</percentdd>

That should solve any conflict. I believe you can name the css tag to just about anything you want. I should have realized that someone might be using those tags and made something more generic.

Using XAcars with X-plane 9.70

Dont work for me :( I can get the Time remaining <%=flight.timeremaining%> and Bar Graphics to work. The Distance Reaming works good.

I replace core/modules/ACARS acars.php (In your post says ASCARS.PHP but i think is not the right file name) file with the code you post, Add the css to my liv/skyns/CGA ( the name of my Skyn is CGA)css and add the Gif files to lib/images directory.. and acarsmap.tpl to the core/templates.

Any idea,
