COOL FEATURE
Airways and Flight Plan Creation
The FMS can use published airways in its database
to quickly build long flight plans with few keystrokes.
When a flight plan waypoint is a valid airway entry
or exit point, the list of available airways is
presented in a drop down box. The list is quickly
scrolled to the desired exit point and then all
intermediate intersections along that airway are
automatically populated into the flight plan.
The pictures below are an example of the airway drop down box
that is displayed when building a flight plan and then the exit point
choices once the airway is chosen. Use the bottom right IFD
knob to scroll the list for the desired airway and exit point off the
airway. The exit list is presented in the order by which the
intersections will be reached, not in alphabetical order.
