I having the same problem with my map, its set to 720/12 hours and they still show up, all i know is when they do go away it was a week later when one of my pilots aircraft on there finally went away..
Well i know for a fact i have seen it on the map where it says status is “Arrived” and it still doesn’t go away, i changed my settings to 480 for 8 hours and i have already seen one pilot status go away…maybe this will work?
Hm, you know guys. My math might have been wrong.. LOL.
I said 720, /60 would give the hours, but instead I divided by 12, to give 60 hours. I mean to divide by 60. D’oh!! I must not have been thinking… way to confuse myself.
So set it to 144, that’ll give you a 12 hour timeout (just do the hours by 12 for now). I’ve fixed that…
But if you wanna leave it at 720, check core/common/ACARSData.class.php, line 184ish, change the 12 to 60.
