Distance & Direction. In addition to the old four-beam, low-frequency (200-400 kc.) radio ranges, the airways are now dotted with very-high-frequency (108-118 mc.). Omniranges (TIME, Dec. 20 1948). They cover limited distances (200 miles at 20,000 ft.), but are far more versatile than the old-style ranges. Almost unhampered by static, they give the approaching plane a straight-in heading from any direction. Rather than flying on a narrow, crowded beam, a pilot can tune his Omnirange receiver to the desired station, then read his course on a dial...
...Landing. For foul-weather landings, the common system includes both radar-directed, ground-controlled approach (GCA) so popular with the military, and the instrument-landing system (ILS) that is preferred by airline pilots. At airports equipped with both systems, planes can make their final approach down the ILS radio beam, while alert ground crews give extra guidance through...

...recent radar scare, which occured when radar scope operators in Washington, D. C., observed unexplained patterns on the screens of their instruments, is also explained. While radar cannot reflect an optical illusion, the radar beam itself may bounce around in such a manner that the "blips" produced can be mistaken for solid objects...
...transmitters will go off the air. All AM transmitters will either be silenced or will switch their frequencies to 640 and 1240 on the dial of any standard receiver. This technical jugglery is necessary in order to prevent enemy pilots from getting a "fix" on a normal radio beam and riding down its path to drop bombs on a target city...
