Question: Where should I store Runway Visibility Zones in a data set that complies with AC 150/5300-18B?

Answer: Runway Visibility Zones are not explicitly required by AC 150/5300-18B, but sometimes requested by the FAA on a case-by-case basis.

If requested:

1.     Record the Runway Visibility Zone as a RunwayHelipadDesignSurface.

2.     Set the designSurfaceType to “TSA” for Threshold Sighting Area.

3.     Enter “Runway Visibility Zone” as the name.

4.     Enter in the description, “Runway Visibility Zone recorded as type TSA, by direction of the FAA Airports-GIS Program Office.”
