SANDEL SN3500 Electronic HSI Primary Navigation Display

With more than 4,000 compact EHSI systems in service, Sandel knows something about integrated compact displays. So you’d expect a turbine-class, 3-ATI drop-in retrofit system from Sandel to be nothing less than revolutionary.

And that’s exactly what the SN3500 Electronic HSI is, combining advanced navigation capabilities, a bright, ultrawide- angle display and a full range of safety functions.

Incorporating the equivalent of a four inch screen in a three-inch instrument, the SN3500 improves situational awareness by presenting Compass, Map, Flight Plan and RMI data in a bright, crisp, easyto- read format. FAA-certified as a primary flight display, the SN3500 can even show overlaid Stormscope® weather and traffic information from TCAS, TCAD and TAS receivers, maximizing situational awareness.

As impressive as the baseline SN3500 unit is, the SN3500 system offers even greater capability, through its expandable Input/Output. Enabling the system to work with almost every aircraft type and configuration, this built-in module supports both analog and digital avionics systems, saving on installation time and cost, and ensuring that all your navigation sensors are properly utilized.

Moreover, our smart I/O also helps your SN3500 add new functions. With a software upgrade option from your dealer, you can add traffic displays for TCAS, TCAD and TAS, with targets overlaid on your flight plan, and datalink weather information.

Selected Features:

• Internal Jeppesen NavDataTM database supplements IFR flight plan data and approach waypoints derived from your GPS receiver’s IFR-approved database
• Graphical bearing pointers and digital bearings supplied for any selected navigation source
• Dynamic data tags show fixes and waypoints
• MEM feature allows you to pre-configure two separate situational views and toggle between them with a single keystroke
• One-touch declutter for each display item
• Approved for use as a primary heading and NAV display
• Ideal for light turbine, high-performance piston and rotary-wing aircraft

Key Functions:

• Displays GPS vertical deviation from WAAS-enabled GPS receivers
• Sharp, sunlight-readable display with ultra-wide left-toright and up-down viewing angle
• Bright, nine-square-inch screen comparable to many four-inch EFIS displays
• Full-color moving map supporting GPS-supplied waypoints, heading, bearing pointers for VOR and ADF, DME display and marker beacons
• Upgradeable system combines navigation with such safety options as traffic, Stormscope and datalink weather
• One-touch toggle between 360-degree compass and 70-degree ARC view
• HDG and CRS sync functions automatically set the heading bug directly to your current heading, or the course pointer to a VOR station
• Auto-slew function simplifies waypoint sequencing and Direct-To GPS navigation, allowing you to fly an entire GPS flight plan, hands-free
