2. Introduction
2.1 General Description
The TI106 CDI is designed to operate with VHF and GPS navigational equipment to provide OMNI (VOR), GPS,
Localizer and Glideslope information.
The TI106 is designed to accept DC signals for Left/Right and Up/Down pointer deviation and Valid/Invalid
(“flag”) status from a remote mounted VOR converter. It also provides annunciations for NAV, BC, and GPS
indication of the incoming source or mode and a TO or FR (from) annunciation to indicate direction of the ground
signal or course waypoint from the aircraft.
The Omni Bearing Selector (OBS) course resolver provides the compass card position as an electrical output (a
phase reference signal which is ORZ zeroed to an industry standard 300°).
The TI106 CDI uses white LED unit lighting to illuminate the dial and pointers. It can be brightened or dimmed
with an external lighting bus voltage for 5, 14 or 28V systems. Additionally, the backlit LED annunciators are
automatically adjusted for appropriate brightness using a built-in photocell sensor which can be calibrated at the
time of installation.
