1. If the highest zoom level (the farthest out) covers an area of roughly 80*60 (I could be quite off on this value *Edit) squares and a runway has a length of 3.000m at 5m/square -> 600 squares length of a runway, so we see just about more than 10% on the highest zoom level - it seems a bit tough to keep track of your airport that way.
On my screen resolution 1680x1050, playing P1SIM in fullscreen mode, max zoom ("far"), there are 210 horizontal tiles visible. And the runways wont be 3.000m long in P1SIM. Probably 1.500m or less. Thus you will be able to see more than half of the runway or even the complete one. Depending on your screen resolution and the final decision about runway length.

2. Integer.MAX_VALUE = 2 million something in java, right? That means, we have a side length of the map of more than 10 million meters - or 10.000 km, thus an area of more than 100 billion km² (100 Milliarden auf deutsch)? That's insane. Crazy - great! But there's only this one map, right?
Max integer value is 2.147.483.647 Thus the randomly generated map (you get a new map when starting a new game; except you decide to manually set the map seed) has a size of 4.611.686.014.132.420.609 tiles.
3. If there is only this one large map, how are we gonna find back to our "home town", after scrolling in some direction?
Select a train, a city or any object in one the many overview lists and the map view will jump to that object.
And how is the user going to get an overview of the whole map? To know, where he wants to plan his new railway tracks or airport? I'm guessing the distance between two airports will be kind of the same as in reality.
There is a minimap. And Im planning to implement a zoomable minimap, so that you can even zoom out the minimap.
