# of Segments and Description
Entry Exit
Holding pattern outbound leg (length
based upon either time or distance
as specified by navigation database).
Turn to holding pattern inbound leg
(180°).
Holding pattern inbound leg (length
based upon either time or distance
as specified by navigation database).
7.3.5. Direct-To
If the EFIS generates a WGS-84 geodesic path to a designated “To” fix,
the aircraft captures this path without “S-turning” or undue delay. Where
the selected “To” fix is in the active flight plan, the required transition is
created as follows:
1) A phantom waypoint is created at the current aircraft location.
2) Leg prior to the phantom waypoint is designated as a discontinuity.
3) Phantom waypoint is designated as a fly-over defined entry heading
waypoint where the entry heading is current aircraft track.
Where the selected “To” fix is not in the active flight plan, the required
transition is created as follows:
1) A new active flight plan is created from “Start” (current aircraft location)
to the “To” fix.
2) “Start” waypoint is designated as a fly-over defined entry heading
waypoint where the entry heading is current aircraft track.
7.3.5.1. Direct-To Unnamed Waypoints inside Procedures
The following identifiers are implemented for unnamed waypoints inside a
published procedure and are found on the ND or inside the active flight
plan.
1)
-ALT-
for altitude terminations
2)
-DIR-
for waypoints that begin a Direct-To leg
3)
-DME-
for distance or DME terminations
