I have a small question to ask...
Is there a terrain editor that can flatten terrain in FS2002?
There is an airport of mine in India that the tarmac keeps 'flickering' when I taxi or fly past it/on it. I think it's because the terrain the tarmac is built on isn't level. Is there an editor out there that can solve my problem?
Thank You for any help anyone can provide.

P.S. =

Also, I'm using a really old scenery creator. I think it's called "Ultimate Scenery" by LAGO. Is there an editor that can add real tarmacs, structures, and taxiways to FS2002?
