...Burnham zeroed in on Nantucket-and ran into one of the island's murky flash fogs, rolling in from the sea with bewildering speed. Burnham, using Nantucket's Visual Omni Range beam, prepared for an instrument approach. But the fog thickened until even VOR was ineffectual. With its field socked in, Nantucket tried to warn the Convair by voice radio-and could not reach it. Flight 258 came in for its landing, flying low over scrub pines. It plowed into the ground 600 feet to the left of the runway. Dead when the wreckage was cleared were...
...operation. The plan calls for 138 surveillance radars for close-in airport traffic control; only 45 are in operation now; another 16 are programed for early 1960. The plan also includes 23 precision-approach radars (ten now operating), 289 traffic-control radar beacons (none operating), 677 omnidirection radio units (VOR), 573 short-range navigation units (VORTAC), 235 instrument-landing systems and another 69 airport control towers...
...Washington's bitterest technical squabbles, the long rivalry between aircraft-guidance systems, reached a new phase last week. The Air Coordinating Committee announced a compromise plan that looks like a desperate attempt to offend no one. The plan recommends that both guidance systems, VOR (Very High Frequency Omnirange) and TACAN (Tactical Air Navigation) be "combined" under the hybrid name of VORTAC...
...VOR, with "Distance Measuring Equipment" (DME), is the present civilian-guidance system. The Civil Aeronautics Administration has installed 480 of its ground stations, and will install 82 more during the current fiscal year at a cost of $86,000 a station. The stations tell a properly equipped airplane its direction and distance...
Under the compromise proposed by the Air Coordinating Committee, the VOR stations will continue indefinitely to tell aircraft their direction. They will gradually stop, however, telling aircraft their distance. In many cases this service will conflict electronically with TACAN and so must be eliminated. Unless the Government foots the bill, civil-aircraft operators will eventually have to buy costly new electronics. Cost of a full VORTAC system...
