Most holding patterns are part of a procedure or airway and remain active until the
flight crew executes an exit from holding. This may be accomplished in one of two
ways:
• on the ACT RTE LEGS page, deleting or bypassing the HOLD AT
waypoint causes LNAV to command a direct to the next waypoint
• on the ACT RTE HOLD page, selecting and executing EXIT HOLD>
causes LNAV to command the airplane to continue in the holding pattern
until arriving at the holding fix, at which time the airplane exits the
holding pattern.
Following execution of the exit hold, only the remaining portion of the holding
pattern back to the holding fix displays. Exit from the holding pattern may occur
prior to crossing the holding fix (“fly-by”) if the course to the next waypoint is not
closely aligned with the holding inbound course. The exiting flight path will
remain within the confines of the protected holding airspace. The exit flight path
displays on the ND.

FMC Descent and Approach
11.43.32 Boeing Proprietary
The FMC automatically commands an exit from some holding patterns in
procedures under the following conditions:
• for instrument approach holding patterns designed as a course reversal in
lieu of a procedure turn, the airplane exits holding upon arrival at the
holding fix inbound. Header at 1L displays PROC HOLD
• for some holding patterns in SIDs, the airplane exits holding when
arriving at an altitude. Header at 1L displays HOLD AT.
Push – displays a new hold page for a new holding pattern entry.
Push -
• arms a holding pattern exit
• EXIT ARMED displays in shaded white; when executed, airplane returns
to the holding fix via the inbound course for holding pattern exit.

Boeing Proprietary 11.50.1
11.50 Flight Management, Navigation-Alternate Navigation System Description Introduction
In the unlikely event that loss of all displays or loss of all three FMCs occurs, a
backup navigation capability has been provided through the Tuning and Control
Panel (TCP). Alternate navigation information is displayed on the ISFD allowing
the aircrew to safely fly to and land at the nearest suitable airport. Alternate
navigation capability is accessed by pushing the NAV key on any of the three
TCPs. VNAV is not available. Autothrottles may be available. The left TCP must
be used to tune ILS/GLS frequencies into the left integrated navigation receiver.
Alternate Navigation Waypoint
The TCPs do not have a performance or navigation database. A single waypoint
may be manually entered by the flight crew on ALTN NAV page 1. The waypoint
may be updated as necessary.
Alternate Navigation Page
This page displays general data about flight progress.
