I've been practicing on the manual landing of a 747. I'm getting a little better. Procedure wise, I suck at it right now, but I'm starting to get a better eye at judging where the airport is before it comes into view. Check out:

I flew out of Seattle/Tacoma and then circled back and landed on the same runway I took off from. Realism settings are set to Hard. I kept getting audio errors like too low terrain and all that stuff but I didn't crash so there!
Be gentle. 8-)
