Sandia Aerospace

  • 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  
  • SI-11X also displays four Annunciations, NAV or VLOC, GPS and BC (Back Course)
  • All Solid State. No mechanical needles or flags
  • The SI-11X will interface with virtually all VOR and GPS navigation units
  • Displays both VOR/LOC and GPS deviations
  • Annunciates GPS, VLOC & BC
  • SI-11X mounts in a 3 1/8” standard instrument hole
  • Good replacement for most mechanical CDI’s including the GI-106A
  • Upgradable
  • High visibility
  • Small and light weight. Just 1″ behind the panel
  • Fits standard 3-1/8″ round mounting hole
