Tour
The HSI depicts your (ground) track heading using a
rotating ‘compass card’. Don’t confuse this with the
aircraft heading indicated on your panel. On a windy day
these two figures can differ significantly.
The HSI page also provides a TO/FROM indication
and vertical guidance, when using the unit’s vertical
navigation (VNAV) features. Four user-selectable data
fields indicate current speed, distance to destination, time
enroute and time of day.
Highway Page
Like the HSI Page, the Highway Page also provides
graphic steering guidance to a destination waypoint. You
can use the Highway Page instead of the HSI Page as your
primary navigation page when your main concern is
following a defined course.
Your present position is at the bottom center of the
highway display.
The line down the middle of the highway represents
your desired course. As you navigate toward a waypoint,
the highway will actually move—indicating the direction
you’re off course. To stay on course, simply move toward
the center of the highway.
The fields at the top left of the page show speed and
distance to your destination (or the next waypoint in a
route), along with a track compass showing current
direction of travel.
Across from the speed field is the time required to
reach your destination (or the next waypoint in a route),
in hours/minutes or minutes/seconds. The pointer shows
the bearing to your destination, relative to your current
track. If the pointer points straight ahead, you’re heading
directly to your destination.
