Altitude Restriction (AT XXXXX)
Displays the next waypoint constraint from the RTE LEGS page.
The constraint is speed/altitude. If an airspeed restriction exists at the waypoint, it
will be displayed in large font; otherwise the predicted speed will be displayed in
small font.
Can be deleted on this page.
The display is blank when no constraint exists, or for any DES page if a path
descent is not available.
3
To Waypoint (TO XXXXX)
Displays computed ETA and distance to go to T/D when not in an active descent
mode.
If an early descent is in progress (initiated using DES NOW prompt), ETA and
distance to go to original T/D is displayed until passing the T/D.
If a descent mode is active, displays ETA and distance to go to the first of the
following points:
• the waypoint in the AT XXXXX line
• an intermediate T/D (TO T/D – XXXXX, where XXXXX is the
altitude).
The display is blank if a path descent is not available, or if the AT XXXXX line is
blank and no T/D information is displayed.
4
Waypoint/Altitude (WPT/ALT)
Displays the waypoint and altitude that serves as the basis for the vertical bearing
(V/B) display on line 4R.
Normally displays the same waypoint/altitude restriction that is displayed on the
AT XXXXX line.
May be overwritten by pilot entry.
A runway identifier may be entered for a runway at the destination airport of the
active flight plan. Format may be either RWXX/, RWXXX/, RWXX/AA, or
RWXXX/AA where XX or XXX is the runway designation and AA is the altitude.
When RWXX/ or RWXXX/ is used the altitude will automatically be set to
runway elevation plus threshold crossing height.
Dash prompts are displayed if there is no entry.
