3.18 Flight Procedure Basics
NOTE
Advisory climb altitudes for SIDs may not match charted altitudes. Do not
rely solely on advisory altitudes.
•
Always check the runway, transition, and waypoints for all procedures.
•
Heading legs indicate in white as “HDG XXXº” on flight plans.
•
The unit provides lateral and, when appropriate, vertical guidance for visual
and GPS/RNAV approaches.
•
Use Map as an aid to situational awareness during ILS, VOR, NDB, and
non-precision localizer-based approaches. A magenta line depicts the active
leg (or the portion of the approach currently in use).
•
Always use the appropriate radio navigational aid for primary approach
course guidance during non-GPS approaches.
•
Check the annunciator bar for the current phase of flight.
•
Many non-precision approaches have GPS overlays, improving accuracy so
that approaches do not require overflying a VOR or NDB.
•
The unit guides you through complex overlay approaches, automatically
sequencing each leg up to the missed approach point.
•
Fly approaches as published with the full transition using any published
feeder route or initial approach fix, or with a vectors-to-final transition.
•
While not required under TSO-C146e, an optional baro-corrected altitude
source is recommended for automatic sequencing of altitude leg types.
When adding procedures to a flight plan:
•
Arrange procedures around the existing flight plan as follows:
Departure, En route, Arrival, Approach
•
Insert departure waypoints before en route waypoints
•
Insert arrival waypoints between en route and approach waypoints
•
Always verify that the transition waypoints between each phase are correct
Map complements your printed approach plates by improving situational
awareness during the approach. It does not replace printed approach plates.
Always fly an approach as it appears on the approach plate.
