Answer: The runwayDesignator and runwayEndDesignator attributes have been added to the Obstruction Identification Surface feature class in the version of AC150-5300-18B dated May 21, 2009.
Populate the runwayDesignator attribute with a valid runway designator (for example, 22R/4L) for the Vertically Guided Runway Primary Surface (VGRPS), Vertically Guided Primary Connection Surface (VGPCS), and Vertically Guided Approach Transitional Surface (VGATS).
