I don't know how you write your flightplans, but I use TTools and I just write the code in 3 seperate .txt files: "xxxx Airports.txt", "xxxx Aircraft.txt", and "xxxx Flightplans.txt" with the xxxx being replaced with whatever that set of flightplans is for (IE, "174thFW Airports.txt", "174thFW Aircraft.txt"....etc.)
So, I will break it down for you:
AC#1,58-0104,25%,WEEK,VFR,1/09:00:00,TNG1/10:15:00,060,F,04,KIAG
AC#1 - Aircraft repaint designated as number 1 from the "Aircraft.txt" file
58-0104- The serial number of this aircraft
*1
25% - The percentage your AI setting in MSFS must be at for this flightplan to activate
WEEK - This flightplan is written in a week format (Mon, Tue, Wed....), meaning it will repeat weekly
VFR - VFR flight rules (As opposed to IFR)
*2
1/09:00:00- Departs on monday (1), at 09:00:00
*3
TNG1/10:15:00- Does touch and goes until monday (1) at 10:15:00
060 - Will fly at this altitude while airborn (6000ft)
F - Aircraft will use a callsign (IE "Reach" etc)
*4
04 - Flight number added to callsign (IE, "Reach 04")
KIAG - Arrival airport for the previous data
So in short, the aircraft will depart wherever it ended up from the last flightplan at 09:00:00 on Monday and will do TNGs at KIAG until 10:15:00 on Monday.
For a week format like this, you have to make sure that the entire set of flightplans ends where it began. IE, it can leave KIAG on monday at 09:00:00, but it must arrive BACK at KIAG before 09:00:00 on the following monday to repeat the process. Basically, make sure your Flightplans are a loop. If you are using TTools I HIGHLY recommend reading the ReadMe as that's where I learned everything. It's pretty self explanatory, Good luck!!
*1 - You may use the same repaint for more than 1 aircraft as long as the serial numbers are differnet. IE:
AC#1, 58-0104....
AC#1, 58-0105....
*2 - For TNGs the flightplan MUST be VFR or the aircraft will do missed approaches instead of TNGs
*3 - For a week format, 0 = Sunday, 1= Monday, 2 = Tuesday etc....
*4 - If you put R here, ATC will use it's serial number instead of a callsign. F and R are the only choices
