...comparatively few airplanes or stations have the full distance-measuring equipment. But a navigator or pilot can get a fix by tuning in two stations and getting his bearing from each. His position is the point where the two bearing lines cross on the chart. VOR/DMET uses very high frequency radio waves, which are seldom bothered by static from thunderstorms. Disadvantage is that high frequency waves are line-of-sight (like those used for TV), and therefore stop at the horizon. Airplanes flying above 20,000 ft. can detect them 200 miles away. But for low-flying airplanes and helicopters...
...line can be drawn on a chart to show all such positions, other lines to show places at unequal distances (half as far, 0.8 as far, etc.). The receiver simultaneously measures the distance from the third slave station, and this information generates other theoretical lines on the chart. If the airplane is on two lines of different sets, it must be at their point of intersection...
...developed the most nearly trouble-free gadget yet devised by man. On an average, the telephone man has to repair a phone only once every two years. The party line, that inspiration of jokes and gossip, is all but gone. About 94% of U.S. telephones are now on the dial system, and 8,000,000 customers in 758 communities have direct distance dialing, which enables them to dial some 2,500 cities across the U.S. without going through an operator. This year Washington will become the first big Metropolitan area to have complete direct distance dialing...
...just like the average telephone subscriber-and so do the presidents of his subsidiaries. They also answer their own phones and make their own business calls. Walter Koch, president of the Mountain States Telephone & Telegraph Co., sometimes gets up at night to answer his telephone, sometimes finds on the line a drunk who berates him for some imagined wrong. He has heard more than one turn and shout to his fellow tipplers: "Listen to me give hell to the telephone company president!" Says Koch philosophically: "It does them good to let off steam...
...streams of enticing ads it pushes telephone extensions ("What a beautiful way to save steps!"), phones in color (more than 8,000,000 in the U.S.), and frequent use of the long-distance wires to call Granny (three or four kids are usually pictured waiting to get on the line-and they usually do). "There are still elderly people who worry about when their three minutes are up," says Fred Kappel happily, "but young -people pay no attention...
