The Sandel Avionics SN3500 ColorMap HSI packs the essential features of an EFIS nav display into a standard three-inch instrument, at a fraction of the cost of a full EFIS. By combining the functions of an HSI, an RMI, a moving map and a Stormscope display into one instrument, the SN3500 ties together the critical elements of situational awareness. And by adding to that a 3-light marker beacon display and GPS annunciator display, the SN3500 becomes the virtual equivalent of an EFIS nav display, sized and priced for GA cockpits. With a usable image spanning the entire instrument, the 3-inch SN3500 actually provides more viewing area than most high-end 4-inch displays. Now with TAWS, TCAS 1, and Stormscope interfaces!

The Bendix/King KI 525/825 Electronic Horizontal Situational Indicator (EHSI) combines traditional heading and navigation functionality with mapping and an optional traffic display in a highly reliable, true 3 ATI format. At the touch of a button, a pilot can configure the presentation to display only what’s required for the 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.

The Century NSD-360A combines a vertical compass card and an omni bearing course selector with course deviation for a map-like perspective. This greatly simplifies visualization of position and navigation track. Glideslope indication is presented to the left of the compass card. "Barber-striped" flags provide conspicuous warning indications for NAV, glideslope, and heading. Magnetic slaving is optional.
