A Clear Picture of Safety
Honeywell, using its steadfast experience in Air Transport and Business Aviation safety systems, now offers the same situational awareness technology in the most advanced display system ever offered to General Aviation. The KI 825 Electronic Horizontal Situational Indicator (EHSI) combines traditional heading and navigation functionality with moving map display in a highly reliable, true 3 ATI format.

The KI 825 displays critical navigation information in an easy-to-use, high-resolution presentation. At the touch of a button, a pilot can configure the presentation to display only what’s required for that phase of flight. This capability greatly reduces workload as only the desired information is presented in the pilot’s primary scan. All this is provided by a unique razor-sharp, sunlight-readable, crystal clear display – giving you the confidence and capability to make flying easier and more fun.

Features:

• Electronic Horizontal Situational Indicator (EHSI)
• Provides display and overlays of Heading, VOR NAV, GPS, and Lightning data (see Screens)
• 3 inch ATI format
• Uses a combination of menu selections stored internally and/or optional external configuration module to determine specific instrument functionality required by particular aircraft installation (see Configuration)
• Dimming and backlighting adjustable
• Able to select between four navigation sources - VOR1, VOR2, GPS1, GPS2
• Annunciation provided to indicate nav source (see above)(Note: nav source annunciation may not be displayed if external relay switching is used in aircraft instead of KI-825 internal switching)
• Version available with Night Vision Goggle capability (see table below)
• Original production versions (-0X01) do not include external nav source switching configuration which allows the selected NAV source to be changed by compatible nav unit or by external switch (see table below)
• Original production versions (-0X01) do not include selected course retention configuration which allows the selected CRS to remain set to the same bearing between NAV and GPS sensor changes (see table below)
• 11-33 VDC power input
• Two-year, 5000 hour warranty
• Retrofit kit available for KCS-55A HSI (KI-525A) replacement
