MARKER BEACON (P/N CI118-1) - As Removed

The CI118-1 is a marker beacon receiver that detects 75 MHz signals from outer, middle, and inner markers during instrument approaches. This avionics component integrates with ILS systems to provide cockpit annunciation and visual indication of marker passage during precision landings. Installed in the aircraft lighting and navigation system, it receives low-frequency marker transmissions and triggers appropriate panel indicators to alert pilots of approach waypoints.

Installation and testing follow aircraft avionics manuals and FAA TSO-C35d standards for marker beacon equipment.
