At those elevations and temperatures you need to think about approach/climb and landing/climb limits. The runway length part of the equation is the easy bit, for landing anyway. It will stop easily in 1500 metres on a dry runway. Depending on obstacles, you could be looking at zero flap for the takeoff to get the required climb gradient, so it starts to get tricky because that really affects accelerate-stop in a big way compared with 16 flap.
And you don't want novice pilots doing 26 flap landings in a -500 because eventually someone WILL scrape the tail.
