VNAV Operational Scenarios
The operational scenarios are presented as a series of figures showing
typical vertical profile segments. Certain points on the figures are
labeled with numbers. These numbers are used to describe events and
are enclosed in parentheses in the text. Refer to the General VNAV
Rules section, when reviewing these scenarios.
VNAV CLIMB (VFLCH)
The elements of a VNAV climb profile are shown in Figure 7--22.
A VNAV climb profile consists of the following:
VNAV is flown in a VFLCH airspeed climb (1) after takeoff.
D
The flight guidance computer changes to ASEL to capture the
D
altitude constraint (2).
The flight guidance computer switches to ALT at the constraint
D
altitude (3).
The altitude preselector is set higher than the constraint altitude (4).
D
The FMS switches to VFLCH as the waypoint is passed (5).
D
The flight guidance computer conducts a normal level off at the
D
intermediate altitude preselector (6) switching from VFLCH to ASEL
to ALT with the normal 1000 ft selector alert.
