MULTIPHASE
VERTICAL F-PLN management 19
Vertical Guidance:
ALT CSTRs are taken into account by the FMGS for target altitude.
Refer to Part II: Climb - Ch 4.3 Constraints management for details.
 {CLB OR
DES}
When the FMGC cannot determine
whether CSTR should apply to step climb
from that WPT or step descent to that
WPT, then "CLB" & "DES" prompts are
displayed at [6L] & [6R], to be chosen as
appropriate by pilot.
Vertical profile is re-computed
accordingly.
In the example FL 330 is entered at
VANAD which is a cruise WPT. T/D is re-
computed to pass VAND at FL330
