More has to do with security, you can keep planes on the south side moving while the north side is working AF 1 or AF 2. But 9R and 22L have both had B747 Dept and 22L even has had the A380 Dept. It is more efficient if they can take the shorter RWY for their direction of flight. If the pilot request a longer RWY we will taxi them there, but they will delay other aircraft if their direction of flight shuts down the shorter RWY. This happens on East flow a lot many of the Heavy’s are North or East bound which is normally where 9R Dept go. We normally always assign RWYs based on direction not plane type.
Check my original post -- the runway I was asking about is 9L-27R, but you are referring to 9R-27L, hence the confusion.
I answered your question in your original post, you didn’t think a 747 would take a short RWY. I advised there have been departures off of RWY 27R. I was all letting you know that large aircraft have taken other short RWYs as ORD like 22L which is 8079 or 9R which is 7967.
I never said a 747 couldn't take a short runway -- I said (or strongly implied) ATC would never assign a 747 to a 7,500' runway when 10,000'+ and 13,000' were available.
