Investigation and Test for a Future Solid-State Terminal VOR Facility.

The report provides technical information from the test at NAFEC, FAA, Atlantic City, New Jersey, of an available commercial 10-watt solid-state VOR to assist in preparing specifications for a future type terminal VOR facility. The investigation included low altitude flight tests by NAFEC project aircraft, ground checks, remote receiver monitoring, and the FAA standard SAFI flight inspection system at high altitude. A conclusion was that solid-state is practical and provides stability and reliability with less requirement for maintenance only if special care is given to design of circuits such as in certain areas pointed out in the report.
