SUBJECT:  Elimination of the Terminal Aerodrome Forecast (TAF)

          Service for the Desert Rock Airport, Nevada (KDRA),

          Effective December 7, 2011


Effective December 7, 2011 at 1200 Coordinated Universal Time (UTC), the NWS Office in Las Vegas, NV, will no longer provide TAF service for the Desert Rock Airport (KDRA) in Desert Rock, Nevada.  Routine and updated TAFS will no longer be issued for this airport.


TAF service was initiated for KDRA in the 1970s when nuclear testing personnel were routinely flying into the KDRA airport. At that time, there was significant air traffic into that field. In 1992, flights into KDRA were reduced dramatically when nuclear testing was banned. In 2009, the FAA changed the airport use to private use, with permission required from the Department of Energy (DOE) before landing. The airport has no control tower and is unattended.
