Problem with flight duration computation on compile

Recommended Posts

Dear all,I have been playing with ttools in the past few days and I am really impressed with the results so far. However I am having a problem in one of the flight plans I have constructed. This flight plan is to be repeated over a period of one week.AC#36,CSTOA,50%,WEEK,IFR,6/23:09:34,0/09:00:11,350,F,1211,FNLU,0/10:44:46,0/20:35:24,360,F,1210,LPPT,0/21:00:00,0/21:41:51,290,F,1577,LPPR,0/22:44:36,1/12:36:24,360,F,1577,SBSP,1/12:24:05,2/02:15:53,370,F,1578,LPPR,2/04:54:37,2/05:36:27,280,F,1578,LPPT,2/10:04:42,2/14:57:33,360,F,1103,GVAC,2/15:24:37,2/20:17:28,370,F,1106,LPPT,2/22:34:03,2/23:15:53,290,F,1557,LPPR,2/23:14:39,3/12:43:04,360,F,1557,SBRJ,3/08:44:22,3/22:12:47,370,F,1554,LPPR,3/21:08:48,3/21:50:38,280,F,1554,LPPT,4/00:29:22,4/14:21:10,370,F,1271,FAGM,4/20:59:50,5/10:51:38,360,F,1266,LPPT,5/08:28:54,5/09:10:44,290,F,1403,LPPR,5/10:04:52,5/21:16:42,370,F,1403,SVMI,5/23:34:31,6/10:46:21,360,F,1404,LPPR,6/08:19:56,6/09:01:46,280,F,1404,LPPTNow, notice that on the first leg, LPPT - FNLU the flight time computed by the compiler is correct, ie, about 9 hours! However, on the return flight, leg 2, the flight FNLU - LPPT is taking double that time. I can't figure out what is the problem.I am thinking of trying to convert this into the Microsoft tools format and give it a shot but maybe someone knows what's going on.The reason for such high number of legs is that I tried a few AI flight plans available and most of them have one problem. As they target single flights most of the time, we end up with a huge number of aircraft in the airports just waiting for their scheduled flight. What actually should be done when building these flight plans is to take into consideration the number of aircraft (of each type) each airline operates. The result of this approach is that these aircraft would be flying a lot more often thus reducing the number of planes parked at the airports which results in better frame rates. It also models reality better. The above flight plan includes the Air Portugal (TAP) real flights for a particular aircraft type (the A340-300 in this case). As there is an additional 3 A343 in this fleet, 3 other plans should be included for the additional flights for each week. In this way, each aircraft spends most of it's time in the air and doing a lot of landings and take offs in various places.Any views on this??Cheersjmf

What do you mean? The first leg takes just under 10 hours. The second leg also takes just under 10 hours.

Hey,You are right!Now I am confused! I think the problem is with the time zones!Both Lisbon and Luanda are on the GMT time zone. However in FS Lisbon is not on the GMT time zone. I didn't check where FNLU is!Maybe this is the problem.Are there any known issues regarding time zones in fs2002??Cheersjmf

Yes. The time zones are only approximate, not exact. Also, there are errors in some places. There is a downloadable fix and patch available here: http://www.flightsimmers.net/ddt/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___

just a quick observation ... question....your first plan is a 6/ ... I thought plans could not start with 6/ and the first leg had to be the lowest number day???-j

It shouldn't make a diference. But it is a good point. In the ttools documentation, there is something about the times being in order but it does not specificaly address this particular case. The main reason for this is that the flight actually starts after midnight according to the local time which was supposed to be GMT. But this is not the case in the FS world. In the meantime I learnt about a patch that solves this problem.Thanks anyway!I will make these files available when I finish! The only problem is to find simple GMAX models to use with this data. I will be looking for TAP colours for A340, A310, A318, A319, A320. For the time being I am using FS2000 models which means no landing gear! However in one ocasion on landing they appeared to have landing gear.jmf

As promised here it is. This is only my first one!!The original problem I guess was the cruise speed used to compute the flight times. I know that this is just to estimate the position of the aircraft at startup. What speed is is actually used by AI engine? If this is very different from the speed used to build the timetable I guess that at some point problems will start to apear if these differ a lot.For this flight plan, you can use the TAP A343 that can be found at camsim. http://pages.infinit.net/camsimAs it is a FS2000 model you have to import it to 2002 using fsedit. You can configure ATC to call TAP the proper way. Also you may need to readjust scrap points. As advised in the ttools documentation it might be a good idea to use a native fs2002 air file. The disadvantage with this model is that the moving parts do not work. The good news is that the impact on frame rates is low. I am waiting for some simple GMAX models. The ideal thing would be to get hold of GMAX models with blank textures for painting of various airline schemes.AC#36,CSTOA,50%,WEEK,IFR,6/23:09:34,0/07:11:54,350,F,1211,FNLU,0/10:44:46,0/18:47:07,360,F,1210,LPPT,0/21:00:00,0/21:36:55,290,F,1577,LPPR,0/22:43:22,1/10:02:35,360,F,1577,SBSP,1/16:59:43,2/04:18:56,370,F,1578,LPPR,2/04:53:23,2/05:30:18,280,F,1578,LPPT,2/10:04:42,2/14:04:38,360,F,1103,GVAC,2/15:23:23,2/19:23:20,370,F,1106,LPPT,2/21:33:45,2/22:10:40,290,F,1557,LPPR,2/23:13:26,3/10:12:57,360,F,1557,SBRJ,3/11:32:56,3/22:32:28,370,F,1554,LPPR,3/22:44:46,3/23:21:41,280,F,1554,LPPT,4/00:28:08,4/11:46:07,370,F,1271,FAGM,4/19:30:00,5/06:48:00,360,F,1266,LPPT,5/08:28:54,5/09:05:49,290,F,1403,LPPR,5/10:03:38,5/19:12:26,370,F,1403,SVMI,5/22:29:18,6/07:38:06,360,F,1404,LPPR,6/08:19:56,6/08:56:51,280,F,1404,LPPTOne final question! When adding parking spaces to an airport with AFCAD is it possible to change the order of these in the list after they are placed? The reason for this is that I want to push the smaller parking gates at the begining so that FS engine starts trying to fill these in first. This will prevent small planes from parking in large gates. I hope!! I tried to change the order the gates in the scasm code but once I loaded it back into AFCAD I got lines crossing all over the place. Any suggestions??jmf

Sure. Just go to List/Parking and drag them into the order you want.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___
