The heart of this page is the Course Arrow with its Course Deviation
Indicator (CDI) needle. It gives you a quick, easy to read visual indica-
tor of the relationship between your current direction (track) and de-
sired direction (course). Pilots familiar with "fly to the needle" VOR in-
struments or large in-panel GPS screens will quickly feel comfortable
with this HSI feature.
HSI Navigation Page, flying TO K11 on a course of 62º. The pilot needs to turn left
to "center the needle" and get on course. The plane is currently 1.53 nautical miles
to the right of the course. The cross track error range is set at 2.00 nautical miles.
The flight is 8.96 nautical miles from the target waypoint.
The course line is an imaginary line drawn from your position when
you started navigating to the destination waypoint. It's shown on the
HSI screen as a segmented course arrow. The cross track error is the
distance you are off-course to the side of the desired course line. The
current cross track error is shown in a text box (XTK), and graphically
by the CDI needle, which is the middle segment of the course arrow.
Dots on either side of the course arrow show the current cross track
error scale, which is a graphic depiction of the cross track error range.
