KDI 572 & KN 63



KDI 572


Bendix/King's Silver Crown KN 63 offers high performance DME features in one compact, low-cost package.

The TSO'd KN 63 is a complete 100 watt, 200 channel remote DME system utilizing the latest-state-of-the-art Large Scale Integrated (LSI) circuit technology. Offering significant advantages in DME reliability and performance, the KN 63 is all solid-state (no transmitter tubes) and can be installed with either single or dual panel indicators.

Distances up to 389 nm (at line of sight altitude), groundspeeds up to 999 knots, and time to station up to 99 minutes are computed digitally and displayed simultaneously on the easy-to-read KDI 572/573 panel displays.

Distance lock on is virtually instantaneous (usually within one second) with accurate ground speed and time to station readouts following in less than a minute.

Simultaneous display of DME distance, groundspeed and time-to-station, plus exclusive RNAV and DME Hold annunciation are provided with the panel mounted KDI 572 or KDI 574 Master Indicators and the KDI 573 Slave Indicator. All displays feature large, easy-to-read gas discharge numeric which automatically dim to adjust for changes in ambient light level. The KDI 572 (or KDI 574 with remote switch) is required in all installations, while the KDI 573 is optional.

The KDI 572 or 574 Master Indicators will accept channelling data from either of two external NAV receivers. A rotary switch on the KDI 572 display is used to turn the system on and select NAV 1 or NAV 2 channelling or DME Hold. The KDI 574 uses a remote switch to control the system. The units will accept several NAV receiver codes. These include ARINC 2 x 5, shifted BCD, slip code parallel tuning, or the exclusive Bendix/King serial tuning. DME channelling wires connect directly to the KDI 572 or KDI 574, making installation fast, easy and economical.

The companion KDI 573 unit is an optional slave indicator with no mode selector function switch. This indicator repeats DME information on a co-pilot's panel display.
