AOPA Pilot Magazine - March 1958 - (Page 52) Ole terminology, it is clear that the only exception to the Common System concept is in the case of military aircraft on operations "peculiar to air warfare." In an industry aa dynamic as aviation, where the growth of traffic is an ever-increasing factor and where technical advances occur almost overnight, stability in terms of equipment, if overemphasized, would become the Achilles heel to further progress. Experience indicates a minimum expectancy of about 10 years for any so-called system. This probably would be the case with VORTAC, once it has been implemented on a system-wide basis. To be adequate from the viewpoint of Air Traffic Control, however, these or other systems will have to be capable of meeting the same performance standards as apply to the basic system, VORTAC, and be capable of permitting flight on and within the confines of the basic VORTAC routes involved in the air traffic control system. tactical operations. With the revised 444 existing VOR'B with TACAN and for new VORTAC facilities will be presented to Congress in succeeding years with the objective of having about 1,260 stations i operation in 1966. General n aviation will benefit, of course, by the addition of new VORTAC routes not now implemented, and by the fact that we plan to space the facilities so that coverage will extend down to at least 700 feet above the ground on the lowaltitude routes. We have installed or have funds for 680 VOR facilities, of which 346 are VORTAC's. Additional VORTAC's will be commissioned at the rate of about 100 to 200 a year, depending: on funds, until the system i corns plete.
