Narrative:

This is a serious safety concern at the intersection of runway 23 and 18L at kclt. There is a significant hump in runway 18L as a result of the crown on runway 23. For many corporate aircraft this location happens to coincide with V1 and/or vr. I was pilot flying on the citation X. The pilot not flying called V1 just prior to the intersection. The airplane continued to accelerate towards vr; but hit the hump prior to reaching vr. As a result the airplane was launched off the hump and became airborne just before vr. There was a very noticeable dip in the left wing as the airplane became airborne. I believe the airport and FAA need to take a serious look at finding a solution to this ongoing problem.

Title: A CE-750 pilot reported the 'crown' of CLT Runway 05/23 at the intersection with Runway 18L acts as a 'launching' ramp for departing corporate aircraft causing them; in some cases; to become airborne prematurely.
