Why not make the touchdown zone of runways wider than the rest?












3















Reasons:




  • Save money by making the rest of the runway narrower

  • Larger margin of error left and right

  • Easier to turn around, if necessary


And if the reason that it isn't done is merely for regulation/legal reasons: Is this something that would be practical if it were allowed?

    It sounds like the underlying assumption is that it is easier to stay centered after touchdown. I think that might not be true, crosswind and e.g. uneven braking power can be problematic even after the wheels are already on the ground.

    Consider the same question phrased a different way could we make some parts of the runway narrower than the rest?, and you'll probably come up with quite a few counter-arguments.

Because most runways already are as narrow as safely feasible.



Let us look at your question piece by piece:




Save money by making the rest of the runway narrower




You seem to be assuming we are currently deliberately wasting asphalt on making runways wider than needed, and could build them narrower. As they say on Wiki [citation needed].




Larger margin of error left and right




The touchdown zone is the whole runway, as long as the aircraft in question can stop afterwards, so if you start down this alley you'll find it cheaper to complete the runway in the same width.




Easier to turn around, if necessary




This is already done by including turn pads, on top of the nominal width. For an example, see: OGZ
