Tom,Can you take a peek at a section of my flight plan I posted here and help me trouble shoot a problem. I have created 2 additional layers for KCVG so that I could control parking locations of certain carriers. This much has been accomplished. The problem I'm having though is all of the DHL aircraft that I have programmed to arrive late in the evening and depart early in the morning is screwed up. From the flightplan below, you can see that I'm attempting to get all DHL aircraft arriving in Cincinnati after 11PM or so and back out before 7AM as in the real world. However, when I load flightsim, I can be at KCVG at 6PM and the entire DHL ramp is filled with DHL aircraft that are not due to arrive until after 11PM. Any ideas?Thanks,Mike----------------------------------------------------------------------AC#43,N34139,50%,24Hr,IFR,00:14:46,01:54:48,330,F,0197,3CVG,05:29:46,07:09:48,310,F,0497,KMCOAC#43,N33729,50%,24Hr,IFR,00:15:50,01:15:57,180,F,0146,3CVG,06:11:47,07:11:54,180,F,0446,KMEMAC#43,N32529,50%,24Hr,IFR,00:25:51,01:25:58,180,F,0157,3CVG,06:28:50,07:28:57,180,F,0457,KMEMAC#43,N33129,50%,24Hr,IFR,00:30:46,01:30:53,180,F,0187,3CVG,06:45:53,07:46:00,180,F,0487,KMEMAC#43,N33729,50%,24Hr,IFR,00:05:49,03:03:10,270,F,0106,3CVG,05:01:49,07:59:11,270,F,0406,KSLCAC#43,N32529,50%,24Hr,IFR,00:20:45,03:18:07,280,F,0108,3CVG,04:18:35,07:15:57,280,F,0408,KSLCAC#43,N34129,50%,24Hr,IFR,00:54:51,03:52:13,290,F,0107,3CVG,05:14:50,08:12:12,310,F,0407,KSLCAC#43,N34529,50%,24Hr,IFR,00:44:50,02:05:42,280,F,0137,3CVG,05:34:52,06:55:44,280,F,0437,KJFKAC#43,N00127,50%,24Hr,IFR,00:59:57,02:20:49,260,F,0163,3CVG,05:59:50,07:20:42,260,F,0463,KJFKAC#42,N00427,50%,24Hr,IFR,22:59:53,02:47:42,310,F,0101,3CVG,04:51:48,08:39:37,310,F,0401,KLAXAC#42,N33129,50%,24Hr,IFR,23:37:52,02:35:13,280,F,0125,3CVG,05:25:44,08:23:06,280,F,0425,KSLCAC#43,N00455,50%,24Hr,IFR,01:28:57,02:25:54,280,F,0105,3CVG,05:39:48,06:36:45,280,F,0495,KATLAC#43,N00564,50%,24Hr,IFR,01:05:56,02:19:56,290,F,0122,3CVG,05:41:44,06:55:44,290,F,0422,KSYRAC#42,N03127,50%,24Hr,IFR,00:35:52,02:37:30,290,F,0191,3CVG,05:04:59,07:06:38,290,F,0491,KMIAAC#43,N32127,50%,24Hr,IFR,22:28:47,00:07:55,260,F,0133,3CVG,04:29:50,06:08:58,260,F,0433,KBOSAC#43,N03427,50%,24Hr,IFR,22:27:54,00:20:45,280,F,0131,3CVG,04:39:51,06:32:42,280,F,0431,KIAHAC#43,N00177,50%,24Hr,IFR,22:42:50,00:35:42,290,F,0155,3CVG,04:57:47,06:50:38,290,F,0455,KIAHAC#43,N02127,50%,24Hr,IFR,22:59:53,00:11:37,210,F,0144,3CVG,04:41:47,05:53:30,210,F,0444,KPHLAC#43,N32127,50%,24Hr,IFR,22:35:49,00:15:50,290,F,0165,3CVG,04:44:46,06:24:48,290,F,0465,KMCOAC#43,N05427,50%,24Hr,IFR,21:28:50,01:30:43,310,F,0188,3CVG,04:56:44,08:58:36,310,F,0488,KOAKAC#43,N67127,50%,24Hr,IFR,00:06:52,01:05:13,260,F,0135,3CVG,03:45:00,04:43:22,260,F,0435,KIADAC#43,N00166,50%,24Hr,IFR,00:46:46,02:10:37,290,F,0153,3CVG,03:43:57,05:07:48,290,F,0453,KJAXAC#43,N00143,50%,24Hr,IFR,00:30:57,04:14:53,310,F,0185,3CVG,03:45:53,07:29:50,310,F,0485,KSANAC#43,N00321,50%,24Hr,IFR,00:31:49,02:17:49,280,F,0177,3CVG,03:49:56,05:35:56,280,F,0477,KDFWAC#43,N00275,50%,24Hr,IFR,01:53:55,03:40:16,280,F,0166,3CVG,06:19:52,08:06:13,280,F,0466,KSRQAC#42,N03127,50%,24Hr,IFR,01:15:46,03:17:25,290,F,0192,3CVG,06:25:51,08:27:29,290,F,0492,KMIA

Mike,Are those times all GMT? If you forgot to add the 4 hours, most of your flights would not be leaving until after 6am. Just a hunch.Warren

What time zone is CVG in? As Warren says, you need to convert these times to GMT. EST is -4 hours, CST is -5. Daylight Savings would make it -5 and -6 (?).Hope this helps,-- Tom GibsonCalifornia Classic Propliners: http://members.aol.com/tgfltsim/index.htmlAlcoHauler Locomotive Page: http://members.aol.com/alcohauler/home/alcohaul.htmlFreeflight Design Shop: http://www.freeflightdesign.com/ San Diego Model RR Museum: http://www.sdmodelrailroadm.com/Drop by! ___x_x_(")_x_x___

CVG is Eastern time which is now on Daylight Savings Time or -4.EST is -5.You might find this site useful:http://www.timeanddate.com/worldclock/CheersWarren

Thanks all, that was the problemo!Mike
