How many times have you been there? Once? For a connection?
First of all 27R/9L is the longest runway at ATL at 11,890' with 26L/8R coming in second at 10,000'. Some of them long-hauls require the longer runway for their accelerate/stop distance.....Hell, 90% can get off in 7,000' but for balanced field length, are unable to. Plenty of heavies DO takeoff from the north side, but I guess you haven't been there when thats happening.
Last week, NWA 92, the SLC-NRT nonstop taxied out to 34L (12,000') at KSLC, waited for a few minutes, then turned around, taxied all the way to
34R (12,004') and took off. The discussion over the radio was Balanced Field Length. Guess he needed the extra 4 feet to have good numbers (accel/stop)....however, the fuel he burned off on the taxiway should have given him enough weight decrease to make his numbers on the 12,000' 34L....I dont know!?
