KNS-81
- Panel mounted navigation system consisting of VOR/Localizer receiver, RNAV computer, and glideslope receiver (basic model)
- Similar to KNS-80 navigation system but DOES NOT include DME section
- Simultaneously displays waypoint parameters of frequency, radial and distance plus up to ten waypoints (TACAN version will also tune TACAN receiver and display TACAN channels & receiving radial information)
- 200-channel VOR/LOC receiver
- Digital RNAV computer with capability for preselection and storage of 4 VOR/LOC frequencies and/or complete RNAV waypoints
- 40-channel Glideslope receiver (optional, see table below)
- Provide OBI outputs for driving an RMI indicator such as KI-229 or KNI-582
- Will operate on any voltage from 11 to 33 volts
- Large Scale Integrated (LSI) circuits used which results in complete unit weighing only 5 lbs. with a low power consumption of 15 watts
- Automatic dimming circuit for display compensates for changes in ambient light level
- Can be interfaced to KN-63, KDM-706 DME units and KTU-709 TACAN
- Commonly used with KI-202 VOR indicator or KI-206 VOR/GS indicator but can be used with KNI-510/510/510B/520/525 or KPI-550A/551A/552/553/553A Navigation indicators, KI-525/525A HSI units, KDI-572/573/574 DME indicators
- No external dummy loads or programming jumpers are required for interfacing
- TSO'd
- Can be used in conjunction with KA-155 FM filter to achieve FM immunity for use in Europe
