OK, let me start with a very basic Traffic Tools 101.
If you've ever played with TT and Traffic BGLs, its usually very easy to get lost in terms of what's going on.
A TT Traffic BGL is built from three text files: Aircraft, Airports, and Flight Plans.
Its easy to get lost in these three text files because most Traffic BGLs tend to be very detailed. There are AI flying off to exotic destinations and you may only see them once a week. THESE carrier Traffic BGLs are much simpler.
The typical Aircraft text file will look like this:
AC#1,200,"
MAIW_NBAI_EA18G_USN_DD_VX-31_166642"
AC#2,200,"MAIW_NBAI_F18C_VFA-86_165198_NH-404"
AC#3,200,"MAIW_NBAI_EA-18G_VAQ-141_166932_AJ-504"
AC#4,150,"Abacus Seahawk LANT AI"
The AC# part identifies a UNIQUE AI aircraft that's located in the main Aircraft folder.
The number next to it can best be thought of as the air speed in the pattern.
The stuff between the quote marks is the most important. It HAS to be an exact copy of the AI aircraft's TITLE line in the Aircraft.cfg file, like this:
[fltsim.0]
title=
MAIW_NBAI_EA18G_USN_DD_VX-31_166642
sim=NBAI_FA18E-F_Super_Hornet_Dry_AI_ONLY
model=G_Centre_Tank
texture=USN_DD_VX-31_166642
atc_airline=DEVIL
atc_parking_types=MIL_COMBAT
atc_parking_codes=VX31
ui_manufacturer=MAIW Nick Black AI
ui_type=Boeing EA-18G Growler
ui_variation=USN - VX-31, Air Test and Evaluation Squadron 31, NAWS China Lake, California. 166642

If the red lines do not match,
exactly, nothing will show up.
Moving on to the Airports file in a Traffic BGL, this is super easy for carrier traffic.
Traffic Tools contains a VERY handy sub-program called
CollectAirports.exe.
This will produce a list of ALL the Afcads installed in your sim as a text file.
I would suggest that you save this list in your Traffic Tools folder.
You only need to run this once if you have all of your carriers installed.
Before you add your carrier, you'll need to know its ICAO identifier (eg, KLAX, AC01, etc.) from the sim's Go To menu.
Open that airports list you created using CollectAirports then right-click the text and use the FIND command and specify the ICAO code.
Find the carriers ICAO entry and copy the entire line, it should look like this:
AC01,N30* 10.03',W80* 40.00',62
This is the ICAO identifier, Lat, Lon, and the true altitude of the flight deck. This location is UNIQUE in FS's main airport list.
To speed things up, I'll show the typical Airports list used in the Carriers2006 scenery package:
AC01,N30* 9.98',W80* 40.00',66
AC02,N29* 9.96',E48* 34.98',66
AC03,S31* 16.96',E153* 21.94',66
AC04,N38* 39.97',E128* 46.96',66
AC05,N37* 1.97',W75* 0.99',66
AC06,N31* 7.97',E18* 8.97',66
AC07,N2* 59.97',E46* 59.95',66
AC08,N21* 59.98',E118* 59.97',66
AC09,N20* 29.98',E91* 59.99',66
AC10,N24* 59.98',E66* 18.97',66
AC11,N33* 14.99',W117* 44.99',66
AC12,N41* 36.97',E19* 2.93',66
AC13,N33* 4.96',E34* 42.97',66
AC14,N48* 18.96',W123* 58.95',66
AC15,N12* 9.96',W87* 23.99',66
AC16,N56* 29.97',E0* 29.95',66
AC17,S24* 59.95',W45* 59.99',66
AC18,S4* 59.97',W4* 59.98',66
Note that you ONLY need the ICAO ident for the carrier you are working on, but a list like this makes it handy to crank out 10-12 traffic BGLs in one night.
Saving the best for last, its time to tackle the Flight Plans.
The Carriers2006 scenery package makes it as easy and as basic as it can get, which I really like.
Sticking with AC01, what you get is this:
AC#3,F18,10%,2Hr,VFR,00:00:00,00:15:00,020,F,0003,AC01,01:00:00,01:15:00,020,F,0003,AC01
AC#1,EA18,20%,2Hr,VFR,00:15:00,00:30:00,020,F,0006,AC01,01:15:00,01:30:00,020,F,0006,AC01
AC#2,F18,30%,2Hr,VFR,00:30:00,00:45:00,020,F,0014,AC01,01:30:00,01:45:00,020,F,0014,AC01
AC#4,SH60,40%,2Hr,VFR,00:45:00,01:00:00,020,F,0124,AC01,01:45:00,02:00:00,020,F,0124,AC01
What you see are four separate flight plans for four AI aircraft. Each aircraft will start up and request taxi to take off.
Then each of them will line up and take off then fly a left-side pattern and request to land.
Once they land (it usually takes a couple of tries) they will then taxi to the closest available parking spot and then shut down.
In case that didn't look obvious in the Flight Plan lines, let me break it down.
AC#1,
EA18,20%,2Hr,VFR,00:15:00,00:30:00,020,
F,0006,
AC01,01:15:00,01:30:00,020,
F,0006,
AC01
AC#1 is an EA-18G Growler that will fly a VFR pattern of take offs and landings for two hours at the AC01 carrier.
It takes off from AC01 and lands at AC01, only. Note the mysterious F code in blue. All that means is that the aircraft will use use its CALLSIGN that is specified in the Aircraft.cfg file along with an arbitrary flight number. This and the EA18 identifier makes it easier to understand who (and what they're flying) is in the pattern when you fly back to the carrier. The rest of the numbers are for timing and position (??). Just trust me, they work just fine.

NOTE ALSO THAT THIS FLIGHT PLAN WILL WORK THE SAME AT ANY CARRIER OR AIRPORT IN FS. The ONLY thing that changes are the two AC01 identifiers in each AC# line. Change them to AC05 and that aircraft will show up at the AC05 carrier. Actually, DON'T do that. When AI aircraft start wandering around in your FS world, odd things will start to happen.
So, this was a long post to show you how EASY it is to modify traffic. I wanted to explain the stuff you really need to know. Making the Flight Plans (especially) complex will usually result in something going wrong. Yeah, you could launch a full Alpha Strike that holds at the Marshal Stack ten miles behind the carrier, but do you REALLY want that?
