A crew from Liberty Mountain Resort and Conference Center today took a “snow day” to assist Baltimore/Washington International Thurgood Marshall Airport with snow recovery efforts. Following record back-to-back storms that dumped 44.3 inches of snow on BWI Marshall Airport, the Airport and the Federal Aviation Administration (FAA) today turned to the snow experts from Liberty, along with some specialized equipment, to help clear snow near important airfield navigational equipment.
Mechanics and operators from Liberty brought a PistenBully 600 ski slope and trail grooming vehicle to BWI Marshall Airport to help clear snow near the Airport’s Runway 10-28 glideslope antenna. The specialized snowcat vehicle was hauled to BWI Marshall Thursday evening on a flatbed truck from Hamner’s Garage in Waynesboro, Pennsylvania.
“I want to acknowledge and thank Liberty Mountain Resort for lending their equipment, their expertise, and most importantly, their employees,” said Paul J. Wiedefeld, Executive Director of the Maryland Aviation Administration. “This was an innovative, outside-the-box solution that brought an important navigation technology back online here at BWI Marshall. The Airport, the FAA, and the airlines are appreciative of the fine work performed by the entire Liberty team.”
The glideslope is a critical component of an Instrument Landing System (ILS), the ground-based technology that provides precision guidance to aircraft approaching and landing on airport runways. The ILS is particularly needed for aircraft operations during poor weather. The glideslope technology provides vertical guidance to aircraft approaching a runway for arrival. Glideslope systems are sensitive to uneven terrain near glideslope antenna equipment. The heavy snow this week at BWI Marshall affected the accuracy the glideslope technology.
The crew from Liberty Mountain Resort and Conference Center used the snowcat to remove and groom snow from near glideslope antenna, located alongside Runway 10-28, one of the major air carrier runways at BWI Marshall Airport.
