Navigation; Course Deviation Indicator (Cdi) - Garmin G5 Pilot's Manual

2.3 NAVIGATION

The G5 will only display data from the #1 navigation source. If the navigation source
is a GNS/GTN unit, both GPS and VLOC data can be displayed

2.3.1 COURSE DEVIATION INDICATOR (CDI)

The PFD Page displays the Course Deviation Indicator (CDI) below the slip/skid
indicator. The HSI Page displays the CDI on the Horizontal Situation Indicator.
The Course Deviation Indicator (CDI) move left or right along a lateral deviation
scale to display the aircraft position relative to the course. If the course deviation data
is not valid, the CDI is not displayed.
The CDI is capable of displaying multiple sources of navigation (GPS, VLOC, or both)
depending on the external navigator(s) configured (refer to the G5 Installation Manual
for more information). Color indicates the current navigation source: magenta (for
GPS) or green (for VOR and LOC). The full-scale limits for the CDI are defined by a
GPS-derived distance when coupled to GPS. When coupled to a VOR or localizer (LOC),
the CDI has the same angular limits as a mechanical CDI.
