AIG Manager offers a vast number of liveries making it often difficult to decide which models to download.
AIG Model Checker helps you select the essential models by examining live traffic at most airports. 
Click on an airport to highlight models you have or haven't downloaded. 
 
Live Traffic 

Obtain live traffic from ANY ICAO airport by clicking on the airport's name.
AIG Model Checker contains all airports used by MSFS2020.

A list of 'key' airports has been included but the user can add new airports using their ICAO codes.

Tip: choose a busy time, ie NOT late at night

All 'missing airlines' highlighted in red are logged and can be accessed by clicking the  'Missing Liveries' tab.

You can create a printed copy by exporting the list to Notepad . Go File,Export Missing Liveries.

You can tweak the parameters for Live Traffic, ie range / height of aircraft.

Double Click on a flight to see picture of plane if available.

Colour Code

Black Lines:Models have been downloaded via AIG Manager and are found on your device.
Red Lines:Models have not been downloaded.When using the map, these models have red lables.
Grey Lines: Models are excluded,ie helicopters,pipers,cessnas etc. 
Dark Brown Lines:AIG models have not been compiled - see below.

The list can be altered by clicking the AIG Missing Liveries tab.
Click on a model in  the  red list and move it to the green list by clicking on the ---> button.

Compiling AIG data

Just locate the 'aig-aitraffic-oci-beta' folder on your device via Options,Main Settings.
Make sure the folder is called 'aig-aitraffic-oci-beta'

More than likely it is located in the Community Folder.

Once located you need to compile the AIG data - this won't take long and must be done everytime you add new liveries via the AIG Manager.

From the main menu Go : Aircraft,Compile AIG Airlines

The program collects airline and model data.

After compiling, check for live traffic.

Look for the Lines in Red & make a note of the airline. Use AIG Manager and download the airline if listed.

Check Airlines

Click the 'AIG Airlines' tab and click on an airline to see what models have been downloaded.

Check Models

Click the AIG Models tab and click on a type to list all the airlines with that type. 

Check Missing Liveries
Click the missing liveries tab to see missing models.
You can use the timer to collect traffic information at given intervals.

Click 'Check AIG Model List' to check if models included in the AIG model list are nevertheless found in your excluded list.

Flight Numbers

Each airport shows incoming and outgoing traffic using arrival and departure boards.

Microsofts 'Live' Traffic is always behind the real live traffic - in some cases it can be 30 minutes!

MSFS uses the numbers of an official Flight Number, not the letters, ie LX1413 becomes Swiss1413

AIG Traffic is not truly live as it is based on flight plans.

VMR

You can create VMR files from current models using the Export Menu.

Logging Traffic
The aim of logging live traffic is to obtain flight numbers at a specific time.
The idea is to collect such data in order to provide a picture of which flights to expect at any given 
time.
Click Live Traffic Tab and select an airport
Right Click and select Edit
Click Log Flights
You need the IATA code for this airport but it should be automatically added when logging live 
traffic.
Untick to cancel logging of this airport
Logged airports have an asterisk in front , ie Heathrow becomes *Heathrow

Flights in grey (ie model of plane is excluded) are not logged..
Number of entries logged are shown on the Live Traffic tab, ie Logged:12
 
Example:
You fly from an airport at 10.22. Click Flights by airport tab and check the Set Time option.
Time is set to your PC time. Click on the Airport's IATA code to provide a list of flights 
previously logged
If you are using Microsoft Live Traffic you have to tweak the number of minutes before the actual 
time, ie 30 mins to obtain the so called current live traffic
