Thanks for telling us your concerns.
Airport data are driven from https://ourairports.com/data/
As Air Italy commented, having accurate data to reflect real world situation is not of the first priority of Alpha testing, especially if it requires manual patching.
The code that generated the airports (and corresponding scales) have been adjusted and I have run the new scripts. Please check and see if the airports make a bit more sense now.
As for missing airports, there are 2 cause:
1. Either the data does not exist in https://ourairports.com/data/ OR
2. The airport cover too little population that we don't want to display (and they will likely get no traffic anyway) - take note that due to current coding limitation we are only showing the top X airports to reduce workload on the browser
I will create a new board so people can report discrepancy for airport data
It's still not much better. Some airports have changed scale, but not always for the better. Some airports even changed for the worse.
Maybe population coverage isn't the best criteria to use for generating airport data, actual passenger numbers make a much better criteria and of course runway length. If you ask me, population coverage should be totally ignored when generating airports. It flaws the airport generation process.
To exclude smaller airports from the game you could of course set a minimum runway length, any airport with a runway shorter than that is to be skipped. That way you prevent all those way too small general aviation airfields being included.
Maybe you should find the cause why Dallas Love Field, which is a busy airport right in the heart of the city (and thus a large population coverage) is being skipped while Addison Airport, which is a general aviation airfield without any airline traffic, is included. Fort Worth Alliance airport, also a general aviation airfield, even gets a scale 6. Why does the airport generation script do that?
I get that you only include the top X airports, but the way that top X is generated is flawed. If necessary, maybe it should be generated manually. Just make a list with X IATA-codes, those are the airports to be included in the game. All the rest should be skipped. I'm willing to make such a list.
