line 1 This line displays AT and blue brackets, if no time constraints exist, or AT,
DIST and RTA when a time constraint has been defined.
The waypoint identifier is displayed in large blue font. If only the waypoint
identifier has been defined, blue brackets and a blue star are displayed
facing the 1R prompt.
The pilot enters the time constraint as “HHMMSS”, preceeded by :
– for at or before ;
+ for at or after ;
no sign for at.
[2L] MANAGED This field displays the FMGS-computed ECON speed/Mach (Refer to
STLO-22_20_R-40-20 COST INDEX (CI))
[3L] ACT MODE This field displays the active speed mode : MANAGED or SELECTED/NNN
(NNN is the target speed).
The pilot cannot modify it through this field.
[6L] RETURN The pilot presses this key to revert the display to the VERT REV page.
[2R] ETA When a required time at arrival has been defined, the 2R field displays the
estimated time of arrival as “HHMMSS”.
[3R] RTA ERROR This field is blank when the RTA is predicted as made.
If the RTA is predicted as missed, “RTA ERROR” is displayed in small white
font, and the time error between ETA and RTA is displayed in small amber
font.
[6R] ETT The Estimated Takeoff Time (ETT) field is available in the preflight phase.
If no ETT is available, the 6R field displays blue brackets and a blue star.
Once available, the ETT is displayed in magenta.
UTC Universal time is displayed in green for takeoff, climb, cruise, descent and
