I hope I am not out of bounds asking this, but it seems ridiculous to me. So there must be a reason why this occurs. I work at STL for the airport authority. We have three runways.
1 - 12R/30L, an 11,019 ft runway.
2 - 12L/30R, a 9,003 ft. runway.
3 - 6/24 a 7,602 ft runway.
I hear requests for jetstream 41's and several RJ's that they want runway 12R/30L for takeoff performance reasons stating that 12L/30R is too short. (heavy) The aggravating thing is that 99% of the time, these aircraft rotate near the halfway point of 12R/30L which leaves nearly 5,000 ft of runway. If 12L/30R was used they still would have 2,000-3,000 feet of runway left.
Is this for rejected takeoff reasons? I was under the impression that once you rotate, you're airborne no matter what happens.
Someone please make some sense of this for me because I think it's stupid why a regional aircraft needs an 11,000 foot runway when a 9,000 footer is more than enough.
