Garmin GPSMAP 295 - Manual (Page 36)

26
Main Pages
The HSI Page appears only when the GPSMAP 295 is in Aviation Mode (see page 6). The graphic
HSI depicts the desired course to the destination waypoint (or the next waypoint in a route), current
ground track, off course error and a TO/FROM indication. The rotating compass card indicates your
current ground track at the top of the page. The desired course pointer and course deviation needle
indicate the desired course and whether or not you’re on the desired course. A bug indicator provides
course to steer (CTS) information, guiding you back to the desired course should you stray off course.
The course deviation scale appears behind the course deviation needle. If you move off course, the
needle will indicate how far off course you are, left or right, based upon its placement along the course
deviation scale. To get back on course and center the needle, simply steer toward the needle. The course
deviation scale setting is adjustable for ±0.25, 1.25 or 5.0 (nautical mile/statute mile/kilometer) full
scale deflection. The default setting is 1.25, which represents the distance from the center of the CDI to
full left or right limits.
As you reach your destination, a TO/FROM indicator at the center of the HSI will indicate waypoint
passage. By default, eight user-selectable data fields appear along the right-hand side of the page
showing: distance and time to next waypoint, name of next waypoint, current ground speed and track,
desired course, cross track error and vertical speed to target (a vertical navigation function, described
on page 79). Each data field may be configured to display any one of twenty-one data options, or you
can replace some data fields with a smaller map display, using the HSI Page Options.
This example shows the aircraft heading parallel to the
desired course, to the right more than 0.5 nm.
This example shows the aircraft even further off course,
beyond the limits of the course deviation scale. The course
deviation needle will stay at the edge of the scale until your
cross-track error (XTK) is less than the limits of the scale.
