APPLICATION OF BALANCED LINES, TONE SIGNALING, AND MICROPROCESSOR CONTROL TECHNIQUES TO A CATEGORY III INSTRUMENT LANDING SYSTEM

The purpose of this partial system design and installation was to evaluate the electromagnetic interference susceptibility and reliability of a microprocessor controlled CAT III ILS monitor and control interface technique using balanced lines and tone signaling techniques. This report covers phase II; Implementation and evaluation of these techniques at NAFEC as applied to a partial system. A full system test is planned under a follow-on program. Details of the results and plans for the full system are contained in the report. (Author)
