There is an event that triggers when 'MiG-31BM Foxhound' lands and changes to the 'Readying' state.
There is also a special action event that shows how the Lua event was created.
The framework was created a few years back for the concept of handling landing/readying/takeoff events, but it was causing exception and run errors. It has been updated with more mature code, but it is still a work in progress so be wary.
For example it will need some limits added to it otherwise the simulation could grind to a halt if there were many a/c being monitored across many bases in a scenario.
