2.6 Horizontal Situational Indicator
The Horizontal Situation Indicator (HSI) displays a rotating compass card in
a heading-up orientation. Letters indicate the cardinal points and numeric labels
occur every 30º. Major tick marks are at 10º intervals and minor tick marks at
5º intervals. A digital reading of the current heading appears on top of the HSI,
and the current ground track is represented on the HSI by a magenta diamond.
The HSI also presents turn rate, course deviation, bearing, and navigation
source information. The “MSG” annunciation will be shown in the HSI when
an unacknowledged message is present on the selected navigator. When the
message is acknowledged, the “MSG” annunciation will clear.
