To Waypoint (TO XXXXX)
Displays computed ETA and distance to go to T/D when not in an active descent
mode.
If an early descent is in progress (initiated using DES NOW prompt), ETA and
distance to go to original T/D is displayed until passing the T/D.
If a descent mode is active, displays ETA and distance to go to the first of the
following points:
• the waypoint in the AT XXXXX line
• an intermediate T/D (TO T/D - XXXXX, where XXXXX is the altitude).
The display is blank if a path descent is not available, or if the AT XXXXX line is
blank and no T/D information is displayed.
4
Waypoint/Altitude (WPT/ALT)
Displays the waypoint and altitude that serves as the basis for the vertical bearing
(V/B) display on line 4R.
Normally displays the same waypoint/altitude restriction that is displayed on the
AT XXXXX line.
May be overwritten by pilot entry.
[Option - FMC U10.5 and later]
A runway identifier may be entered for a runway at the destination airport of the
displayed flight plan.
Dash prompts are displayed if there is no entry.
5
Vertical Path Parameters (FPA V/B V/S)
Displays the following parameters related to the present vertical path:.
• FPA - actual flight path angle based on present ground speed and vertical
speed (that is, the present vertical bearing being flown)
• V/B - vertical bearing direct from present position on the WPT/ALT line
(that is, the flight path angle required if flying direct to the waypoint and
altitude on the WPT/ALT line).
• V/S - the required vertical speed (in fpm, based on present ground speed)
to fly the displayed V/B.
Blank if no entry on the WPT/ALT line.

FMC Descent and Approach
Boeing 737 Operations Manual
Approach
During approach, LNAV and VNAV guidance normally transitions to the
approach guidance provided by navigation radios. The FMC continues to
calculate and display present position and can provide LNAV and VNAV
approach guidance for certain types of approaches when radio navigation is not
used.
The RTE LEGS and PROGRESS pages are used to manage the airplane until other
approach guidance becomes active. Other pages which support approaches are:
• APPROACH REF page - to select the approach VREF
• ARRIVALS page - to select the desired arrival and approach procedures
• HOLD page - to manage holding patterns.
Holding is described in this section but it can be used during any phase of flight.
Arrivals Page - IFR Approaches
The arrivals page allows selection of an approach, standard terminal arrival route
(STAR), and arrival transitions to the destination airport. This page can also be
used to view information about a selected airport that is not the destination. Only
procedures for the origin and destination airport can be selected for entry into the
flight plan.
The approaches, STARS/profile descents, and transitions are displayed and
selected on this page.
