King's KNS-80 is a very sophisticated Integrated Navigation System. In one chassis, it contains a 200 channel NAV Receiver, a 200 channel digital DME, a digital RNAV computer, and a 40 channel Glideslope Receiver. Before the advent of GPS, this was about as much capability as you could get in one General Aviation radio. Even today, the KNS-80 represents a great value.
The RNAV computer allows the pilot to electronically "move" a VOR, allowing more direct flight. The computer also helps with flight planning by providing the preselection and storage of 4 frequencies and/or RNAV waypoints.
The bright Silver Crown gas-discharge display shows the distance, groundspeed, time-to-station, and current waypoint information simultaneously.
The only drawback to the KNS-80 is that it is quite a bit taller than the usual flat-pack radios. This unit is about 3 inches tall. But if you have the space in your radio stack, you can add a lot of capability with a KNS-80.
The KNS-80 also features:
- Internal VOR/LOC Converter
- Self-dimming display
- DME transmit power: 50 watts minimum, 100 watts nominal
Since the King KNS-80 contains an internal VOR/LOC Converter, it is designed to be used with indicators that do not include this converter, such as:
- KI-206 GPS/VOR/LOC/Glideslope Indicator
- KNI-520 GPS/VOR/LOC/Glideslope Indicator
- KI-525/525A HSI (part of a KCS-55/55A system)
