I talked about that in my My idea list (long post) where I described some Incidents/Accidents and how they could cause damage to more than just aircraft or vehicles.
Mostly the parts :
“Runway safety area” which actually would play an important role in preventing accidents or reducing their severity.
“Night and bad weather arrival” where night and bad weather increase the risk of accidents and ILS and PAPI help reducing it, upgrading our ISL and lighting system to gain CAT I, II and III (a,b and c) runway certification not just to allow more flights to land during bad weather (and unlocking higher airline class requirement), but also to reduce the number of potential accidents would be a really great feature.
“Accidents and incidents & Reputation” where I explain that most of those accidents/incidents shouldn’t lower our reputation, though other flights delayed because of that should still as it is our responsibility to make sure operations restart as soon as possible.
“Runway care operations (repair and other maintenance)”, “FOD removal and vehicle type” and “Runway care and maintenance/fuel schedule” is indirectly related as they are all refer to potential causes and consequences of incidents.
And I listed many possible scenario in " Accidents and incidents" that I classed into category based on how bad they affect operations.
This is obvious that Vehicles will wear down as they have condition percentage already and if we look at the F10 debug menu, in “SPAWN STAFF” there is two staff member we don’t yet have which are “Mechanic” probably to repair vehicles and “AircraftMaintenanc” (the last letter(s) are hidden as the name is too long) which is obviously to perform repair and/or maintenance tasks on aircraft.
