• Course projection line — A gray line showing where your present vertical
speed and course will take you with respect to airspace and terrain. Display
course projection line must be selected in the Enroute Chart tab of the
FliteDeck Setup program.
When you zoom in on the enroute chart, the profile view also adjusts, although the
exact scale may vary from your chart zoom level. The profile view shown above is a
typical on-route (OnRte) display. It shows the altitude profile, with terrain and
airspace along the route. Even if you’re momentarily on a ground track that points
toward high terrain or restricted airspace, you will not see those things on the profile
as long as you are on course.
The profile view shown below is what you might see when you are off-course. The
yellow OffRte flag shows in the lower left corner of the profile view. The altitude
profile and the route waypoints are no longer shown. The airspace and terrain
reflects what is ahead of your current ground track under the course projection line.
Displayed Weather in the Profile View
The Profile View displays weather products to help with situational awareness. If your
XM weather receiver connection is active, the weather products always display. See
Weather Products for additional information.
The Supplemental Track Indicator (STI)
NOTE
In order for the STI to appear, FliteDeck must be receiving a valid GPS
position or using the GPS Simulator.
FliteDeck’s Supplemental Track Indicator (STI) looks like a Horizontal Situation
Indicator (HSI). It is not an HSI because it cannot display the aircraft heading
information. Instead, it displays your ground track against your planned course.
Refer to the picture at the right to help the visualize the STI concept.
