DUAL CONTROL

AVIATION IN U.S. WORKING SATISFACTORILY. ' (Australian Press Association). SYDNEY, May 14. Dual control of aviation in the United States was found to work quite satis--1 factor! Iy. So said Mi W. T. Miller, of the ’United States Department of Commerce, yesterday. Mr Miller is at present investigating aviation in Australia. “The position seems to be analogous to that in America, hut we will overI come most of our difficulties by coi operation between State and Federal authorities,” continued Mr Miller. “Broadly speaking, the United States Bureau of Air Commerce controls alt i interstate airways, and the States exercise control in their own domain, either through their own departments or by delegating tlieir authority to the Federal Goernment.” Every machine engeged In interstate transport in America had to carry two pilots, have two-way radio communication' and efficient instruments added Mr Miller? • i Ifftfie i'adim broke down, the machine hath'to land at the first available airport.’ and remain grounded until repairs i had been effected. Airline inspectors were stationed all over the United States, many of them flew the routes with the pilots, and they had summary power to suspend any pilot. The suspension was ifipn reviewed hv I Washington, which decided whether it would he lifted or reimposed. Night lighting beacons were stationed every 15 miles on the main airlines, while meterologieal stations wore provided by the Federal and State Governments, and in many cases bv the airlines themselves. Two-way radio is. not compulsory in Australia, and many airliners are without it. The light beacons which are being installed on Australian air routes are at 50-mile intervals, against 15-mile intervals in the United States. There are no airline inspectors in Australia, though at the beginning of April a number of controllers were appointed —no special meteorological service for aircralt, and no ceiling limits for aerodromes.
