Flight Management, Navigation -FMC Descent and Approach 737 Flight Crew 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.
