There are other external issues as well that are considered. For one, type of a/c using it. At KAPA we have a 10,000 ft. long RY, made of asphalt. WE
want asphalt because SN
melts faster, much quicker to repair, and more considerably we are limited to land larger a/c. 10,000ft is alot of RY, anything can take off or land in that length, but we have a 75,000lb weight restriction. Which limits us to about a G-V and an occasional Global. If we had thicker asphalt or concrete larger a/c would try to land here which for political reasons is not favorable. Teetoboro is under this problem concerning BBJ
traffic. But the main issue is long-term vs. short term costs, including associated maint. costs.
