Panel Page
The Panel Page shows GPS-derived data in a graphical format,
similar to an instrument panel. Keep in mind the differences between
this page and your mechanical instruments, as your mechanical
panel instruments use sensors that provide information different
from that derived using GPS. The Panel Page appears only when the
GPSMAP 495 is in Aviation Mode.
The Panel Page shows a graphic Horizontal Situation Indicator
(HSI) surrounded by additional indicators.

The graphic HSI depicts the course to the destination or the next
waypoint in a route, current ground track, off course error, and a
To/From indication. The rotating compass indicates your current
ground track at the top of the page.
The course pointer and course deviation needle indicate the course
and whether you are on the course. A bug indicator provides
information to guide you back to the course if you stray off course.
If you move off course, the Course Deviation Indicator, or needle,
indicates how far off course you are, left or right, based on its
placement along the course deviation scale. To get back on course
and center the needle, steer toward the needle.
The course deviation scale setting is adjustable for Auto, ±0.25,
1.25, or 5.0 (nautical mile, statute mile, or kilometer) full-scale
deflection. The course deviation scale appears on the lower right
corner of the HSI. The default setting is Auto, which uses three
factors to determine the distance from the center of the CDI to full
left or right limits:
When you are within 30 nm of any airport in the active route,
Auto sets the CDI scale at 1.25.
When you are on an approach leg or within 2 nm of the FAF or
MAP waypoints, Auto sets the scale at 0.25.
If the previous two conditions do not exist, Auto sets to 5.0.
