Is this why pilots sometimes line up "just right of the centre line"? (Those of you who've seen the Cathay Pacific 747-400 DVD might remember Capt Don Grange explaining this to his F/O) I always assumed it was to do with the weather, but then I'm a PAX.
I did wonder if they were really called cats eyes in aviation speak, but didn't want to annoy Rainboe by saying anything...
