EDITING ALTITUDE CONSTRAINTS
The following pages allow the pilot to edit altitude constraints for way-
points on the VNAV WAYPOINT Page, VNAV pages, referred to as
VNAV FPL Pages. One of the three following options may be used:
OPTION 1: Using the VNAV Page.
OPTION 2. Using the VNAV FPL WAYPOINT Pages.
OPTION 3: Using the VNAV WAYPOINT Page.
Option 1: Using VNAV Page

straint may be changed

the altitude field adjacent
to the TO WPT. All
parameters associated
with the former con-
straint will remain
unchanged, i.e., FPA, A, B, G, or OFFSET. (Figure 3-129)
