IFR Procedures
Once the direct-to or flight plan is confirmed, the whole
range of instrument procedures is available to the pilot.
Departures (SIDs), arrivals (STARs), and non-precision
and precision approaches are stored within the NavData
Card and are available using the PROC (procedures) Key.
Displaying the Procedures Page:
Press the
PROC
Key (Figure 1-23).

The steps required to select and activate an approach,
departure, or arrival are identical.
Selecting an approach, departure, or
arrival:
1) Turn the large right knob to select the desired
option (‘Select Approach?’, ‘Select Arrival?’,
or ‘Select Departure?’) from the Procedures
Page.
2) Press the ENT Key to display a list of
available procedures for the arrival (when using
approaches or STARs) or departure (when using
SIDs) airport.
3) Turn the small
right
knob to select the desired
procedure and press the ENT Key.
4) For approaches, a window appears (Figure
1-24) to select the desired initial approach
fix (IAF) or provide a ‘vectors’ option to select
just the final course segment of the approach.
Turn the small
right
knob to select the desired
option and press the
ENT
Key. The ‘vectors’
option extends the final inbound course beyond
the final approach fix, allowing the pilot to
intercept the final course segment beyond its
normal limits.

contained within the selected procedure.
