In my current game I tried to rebase some of my fighters and bombers to a newly built fort, but I couldn't. I checked the civilopedia and it said that forts could be used as bases for air units. Could somebody please help me?

They work for me, I don't know why yours isn't.

Only withhin own cultural boarders iirc. Vassal, Teammate and OB-Partner should count however.

Also there is a limit of 4 (or was it 8 ?) planes you can drop there, so if youhad a stack of more than that, the tile would possible appear as invalid for rebase.

The fort was outside my borders. Thanks Refar! :thanx:

They should re-introduce the airfield improvement imo :) loved it!

(Off topic as the problem was already solved)

I agree :D ! Airbases inside my borders aren't very practical (there's a city always nearby).

Except the hard limits of 4 and 8 for cities. At least you get the ability to base more nearby. This also argues for leaving some space between cities when settling since you'd rarely want to places forts in the BFC.

Well and too you could have considerable culture reach and every tile of range added to your aircraft is potentially very valuable.
