The Si-11X Electronic CDI is a modern, solid-state replacement for traditional mechanical course deviation indicators. Designed for the experimental aircraft market, this non-certified, panel-mounted instrument displays precise lateral and vertical navigation guidance from VOR, ILS, and GPS navigation sources on a bright 3.5” full-color LCD using familiar aerospace symbology.
The Si-11X provides clear Left/Right course deviation, vertical glidepath deviation, and annunciations for GPS, VLOC, NAV, and Back Course (BC) modes. With no mechanical needles or flags, it delivers reliable performance, high visibility, and long service life in a lightweight, compact design that fits directly into a standard 3-1/8” instrument hole.
Compatible with virtually all VOR and GPS navigation units, the Si-11X is the ideal upgrade from mechanical CDI instruments — including the GI-106A — offering modern functionality at an exceptional value.
