THE HISTORY OF AVIONICS
Continued from page 69
by scanning multiple VOR/DME or VORTAC (VOR tactical
air navigation) stations. In the space of one lifetime, pilots had
progressed from navigating by recognition of landmarks to navigating solely by instruments from any point to any other point
within an area served by a VORTAC or VOR/DME.
Furthermore, the pace of change was accelerating. While
pilots were growing to love their solid-state KX-170s and
KN-74s, the engineers at King were already on to their next
step. The first look I had at this was in avionics school. We had
a KNS-80, which was part of the new King Silver Crown line.
Thanks to digital integration and microprocessors, the KNS-80
featured (and still does) a navigation receiver, DME, glideslope
receiver and area navigation system in a panel-mounted package
smaller than the earlier KN-65 DME. My instructor was afraid
of it. These new metal oxide semiconductor (MOS) technology
devices were susceptible to static discharge. As soon as the class
opened the case, the microprocessor got zapped, and the KNS-80
went back for repair. My instructor said, “Don’t even point at it.”

Throughout the 1970s, other companies were stepping up with
new innovative designs. Paul Ryan developed the Stormscope
and the TCAD. Foster AirData developed extremely accurate
and easily useable direct replacements for the King analog area
navigation units. These microprocessors were starting the next
revolution. It took 10 years to go from tubes to transistors. It
took half the time to move from transistors to microprocessors.
Microprocessors fueled an explosion in new technologies.
LORAN-C (long-range navigation) and Omega systems could
be installed in small aircraft, thus giving pilots worldwide area
navigation capability. Small moving-map and multifunction
displays became available. Pilots could add a graphics unit to
their radar, giving their radar indicator limited multifunctionality.
Contrary to conventional wisdom, the next revolution wasn’t
the global positioning system. Indeed, the revolution started
before GPS became available. The Northstar M1 LORAN-C
used database technology effectively, allowing the pilot to
choose a destination without even knowing for sure how to spell
the name of the town, let alone the airport name. Database techContinued on page 72
