The Si-11X Electronic Course Deviation Indicator is a panel mounted device that displays lateral and vertical needles from a typical navigation receiver or GPS navigator. The non-certified Si-11X CDI is intended for the experimental aircraft market.

All information is displayed on a color 3.5” diagonal LCD display in traditional aerospace symbology. The Si-11X displays Left/Right course deviation for VOR, ILS or GPS and Vertical deviation for ILS or GPS. The SI-11X also displays four Annunciations, NAV or VLOC, GPS and BC (Back Course).

The Si-11X will interface with virtually all VOR and GPS navigation units. The Si-11X mounts in a 3 1/8” standard instrument hole and is the ideal replacement for mechanical instruments.
