just drag your existing course line
and have it snap to the nearest fix as when editing a line segment in a typical vector drawing program.
In the profile view it is shown along the course line
AeroNav GPS approaches indicate that the 34:1 slope on the visual segment is clear of obstructions through the depiction of a light grey stipple line connecting the course line
to the runway in the profile view, while there is no indication at all on Jepp charts due to the requirement for international consistency.
If the course line
is ahead of the symbolic aircraft nose, you haven't crossed yet.
The visual of being on or off track can be made even stronger with an extended course line
for the aircraft.
The amount of correction depended on my airspeed, the wind speed, and the angle of wind to my course line
The magenta course line
will rotate on the moving map and the desired track field on the GPS (DTK) will change.
This vector line can also help you fly more precisely: If the line doesn't overlie the course line
, then the aircraft is diverging or converging.
Turning the airplane toward the course line
needle until the bulls-eye centered over the course line
needle yielded the appropriate intercept angle and roll-out on to the course.
There's also a preview feature that shows complete flight plans, including approaches, with a blue course line
as you edit or select so you can see visually what's happening to the flight plan.
But both have the disadvantage of not drawing the desired course line
on our moving map in many GPS/MFD installations.
In crosswinds, an HSI of any sort will show the course line
at an angle to the heading.
