Runways With Markings At Only One End - Why?

Wed Apr 02, 2003 10:34 am

Hi guys.

I'm wondering ...... Why do some runways have a a full set of runway distance markings painted at one end of the rwy to show 500 foot increments of distance past the touchdown zone marks (the large white rectangles), but, the other end only has the touchdown zone markings and nothing more?

I suspect that it has something to do with runways that only allow aircraft to takeoff and land in one direction, however, I've got a mental block as to how pilots would use the available rwy markers in this situation.

I hope this question is clear.

Runways are marked according to what type of approach is associated with it. Visual only runways have the numeric designator, and centerline markings. If the runway is intended to be used by international commercial transports, then it also has threshold markings, and >4000' runways that are used by jet aircraft also have aiming point markings.

Runways with an associated non-precision instrument approach always have all four of the previous mentioned markings.

Runways with an associated precision instrument approach have all of the above, plus touchdown zone markings and side stripes.

Has nothing to do with allowing landing/takeoff in a particular direction.

Yup, they depend on what kind of approaches that end of the runway has.

Though I've never seen a runway with the markings on just the one end.
