Hi. I've spent some time trying to find an explanation of the syntax used in an FS9 flight plan (text file). For instance:EDD,1%,WEEK,IFR,1/05:40,@1/12:00 ... etc. etc.Does anyone know where I can find a document explaining this? Some of it I can make a good guess at, but not all.Thanks,Martin

I don't know if you can still get it here, but look for TTools by Lee Swordy. It tells you everything you should require and it de-compiles and re-compiles your traffic files.edit: it is....ttools202.zipColin B

In addition to the comprehensive Help file which comes with Traffic Tools by Lee Swordy, this Tutorial by Mike Stanton may also be helpful:http://library.avsim.net/search.php?SearchTerm=mike+stanton&CatID=fs2004&Go=Search

I have TTools Colin but I didn't see the kind of detailed explanation I was asking about - I'll look agai..Thanks for the link David. Downloaded - read it tomorrow. (It's 12.30am now.. better retire)Martin

I will try to help you out.AC#2184,N892AT,1%,WEEK,IFR,1/02:00,@1/03:55,370,F,0147,KDTW,1/10:00,@1/11:55,340,F,0252,KATL,1/12:35,@1/14:21,350,F,0444,KBWI,AC#2184 is the aircraft found in the AircraftXXXX.txt file It tells which aircraft to use for this flight.N892AT = aircraft registration number.1% = how often the flight appears.WEEK = frequency of the flight, this flight is a daily flight, flights can also be specific days using 0-6 to specify the day and can even be flown on a particular hour frequency such as 2H, 4H 12H or 24H.IFR = This is the type of flight, either VFR or IFR1/02:00,@1/03:55 = 1 is the day of the week, in this case, Monday and it departs the departure airport at 02:00 UTC and @1/03:55 is the arrival time on Monday UTC.370 = flight level in hundreds of feet, in this case 37,000 feet.F = ATC uses flight number instead of registration ® or tail number of aircraft.0147 = flight number.KDTW = arrival airport.The next flight will depart from KDTW and go to KATL at the times listed before it using the flight level and flight numbers for that leg and will continue on for that particular plan which could have many legs for that one AC. The last airport is typically the original departure airport for the first leg of the flight plan.

Thanks very much for that. I did find information in the TTools ReadMe file too - not sure how I missed it. I'll try some editing now (or tomorrow!),Thanks again,Martin

A slightly better way of creating AI flight plans would be to use AI Traffic Mover by Thomas Molitor. It is a cool program with lots of neat stuff in it.

The Traffic file utility which seems to now be the favorite amongst a great many experienced simmers is AI Flight Planner by Don Grovestine. It comes with a very comprehensive manual also.You can get the latest version here:http://members.shaw.ca/aifp/HIGHLY recommended. :(

Thanks again for the useful posts. I was trying to edit various flight plans and make new bgl files, with the help of various utilities (I am looking at AI Flight Planner now David). The a/c appeared in FS last night, so I think it is working fine. One or two problems still but I'll try to iron them out first before I post about them..Martin

Clarifying:AITM is a freeware powerful GUI front end to TTools. It is available here:http://www.molitor-home.de/FS/Downloads.htmlNote that it was updated for FS9 and you have to install three files in order to make it FS9 effective. You will also need to acquire the FS9 version of TTools from the library here and then place it in the correct folder as noted in the AITM documentation.AITM will let you edit existing AI flight plans. You create a project folder and then load an existing trafficxxx.bgl into it and it will decompile it creating the three necessary .txt files. All AITM processes are extremely memory intensive and some can take several minutes to perform.You can generate a grid based report in several formats with search parameters you specify such as by airline, airline flight, airport, aircraft, etc. You can then modify these, save the changes, and recompile the edited plan. Again don't think your PC has stalled.It is very flexible and with that comes a bit of a learning curve. I used it before becoming lazy and using Ultimate Traffic 2007 but I still use it to add and modify specific flights such as cargo routes which UT does not handle very well.
