Predictions to ALT [2R]:
ALT displayed in [2R] is defaulted to FCU ALT.
UTC (Estimated Time) and DIST (Distance) to reach this altitude are
displayed in:
− [3R] if speed is managed, or,
− [4R] if speed is selected, or,
− [5R] if EXPEDITE mode is used.
ALT may be overwritten enabling predictions computation at any
desired ALT.
When clear, [2R] field defaults to FCU selected ALT.
ACTIVATE APPR PHASE prompt [6L]:
Same rule applies as described for CLB & CRZ pages.
Enables to switch FMGS directly to APPROACH phase in case and
