When an airport closes a runway and builds a taxiway over it. Would they still measure it's true heading even when out of service for years?

    There would be no reason to because the true heading does not change and it is irrelevant to aircraft operations

    True heading won't change.

    No, why would they bother? What purpose would it serve?

    Besides, there is no need for extraordinary measures to assess the orientation. The runway true geographic orientation is known and would not change. Then the magnetic deviation--the one that drifts over time--would be the same for all the runways. And finally, only if the magnetic deviation changes markedly would there be a need to relabel a runway, since the runway orientation is rounded to the nearest 10 degree to determine its number.

    It's not a runway anymore. The numbers would be painted out.

    By the way: runway numbers are based on magnetic north, not true north. But they don't designate either for abandoned patches of paving.

    • My local airport is Shannon EINN. The main runway is 06/24. A runway 23/05 did exist slightly south of the main runway. Another cross runway 13/31 exists but it's mainly used as a parking area now

    Yes. I know that. But would they still measure the true heading of the former runway??

      It’s NOT the true heading. A runway number is determined by the MAGNETIC HEADING to the nearest 10 degrees and the zero dropped

    taxi ramps have letters identifying them, not headings ........

      They already KNOW the true heading of the former runway. It's not going to change.
