 -25- (1) It is our opinion that the operation of the now approved SBRA* is equivalent to the former BRA.* "(2) We accept this SBRA in its present operating condition, "(3) It is also our opinion that the present me thod of monitoring the north leg of the present Salt Lake SBRA is inadequate and that immediate steps must be taken to protect this leg against shifting in either direc- tion. This can preferably be done by either a remotely controlled receiver located not more than 5 miles north of the range station with the monitoring being done at the Salt Lake :control quarters (sic). "(4) In line with recommendation #3 we believe thot continuous and more accurate monitoring is required on all final approach legs at fields located in mountainous terrain. "(5) However, the acceptance of the above-mentioned facility changes in no way our opinion that a completely new range in a better location in the Salt Lake Valley is impers tive, since the present SBRA even as the former BRA affords only the minimum requirements for safety. "We also recommend that a thorough survey be made by a committee of pilots of Western Air Express and United Air Lines, together with Civil Aeronautics Authority engineers, in order to select the best possible site, giving consideration to engineering and piloting points of view. This site preferably should be located north and possibly somewhat west of the present location but not more than 25 miles from the present location. "(6) If this selected site is located at such a distance and direc- tion from the airport that an airport localizer is required, then this recommendation includes the installation of such a facility. "All concerned are agreed that the importance of the above recom- mendations warrant immediate action so that if at all possible an improved facility or facilities can be operating in the Salt Lake Valley by November 1, 1939," The term "SBRA" is the Civil Aeronautcis Administration designation for a simultaneous, scheduled broedcast, full power, vertical radiotor radio range, The term "BRA" is the Civil Aeronautics Administration designation for a scheduled broadcast, full power, vertical radiator redio range.
