Hot Links to Charts
Hot links to the charts directory or individual charts exist in
several locations throughout the IFD including the FPL tab, INFO
tab and NRST tab of the FMS page.
COOL FEATURE
Hot Links to Charts in Flight Plan Whenever a
flight plan leg (blue airfield legs) has at least one
published approach associated with it, a chart icon
is presented on the right edge of the flight plan leg.
If there is a published precision approach, the icon
will also contain an "I". By using touch or the bottom
right IFD knob, scroll through the flight plan
elements until the chart icon is highlighted in
reverse video. If, at that time, the knob is pushed in,
the IFD will display either the specific chart for that
associated procedure or the directory of possible
procedures for that airfield.
