Airport Taxiway Bridges

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I've located some web sites that might be of assistance to you.      -> This is FAA's new large aircraft 
web site.  There is an "issues" publication at      ->  Planning and Design Manual.  4+ MB, so 
it must be more than the page and a half you have.      ->  Link to Airport Design Division

I haven't been able to find any info on the Antonov 124 (AN-124) other than a 
picture of one on Aviation Week's web site (

You might try a search using Dogpile and search for '' "antonov 124" ruslan'' 
with the "'s around "antonov 124".

I think that PCA put out something many years ago about taxiway/runway 
bridges, but it has to be obsolete now.

Hope this helps.
