The transition speed is usually 10 knots less than the destination airport limiting
speed from the navigation database. When no airport limit speed exists, the default
speed of 240 knots displays. The transition altitude is the point the transition speed
is active for the destination airport. When no altitude exists in the navigation
database, the default of 10,000 feet displays.
Speed displays in magenta when it is the FMC speed target.
Blanks below SPD TRANS altitude.
Deleting causes the airplane to fly economy or selected speed if not limited by a
waypoint constraint or speed restriction.
Speed restrictions at altitudes higher than E/D altitude and not associated with
specific waypoints are manually entered on this line.
Valid entry is a CAS and altitude (example 240/8000). Entry may be deleted.
Magenta when it is FMC command speed.
Push – displays the OFFPATH DES page.
Displays the next waypoint constraint from the RTE LEGS page.
XXXXX is:
• the waypoint identifier
• HOLD AT XXXXX
• AT VECTORS
•AT (INTC)
The constraint is speed/altitude. Blank when no constraint exists.
Can be deleted on this page.
VNAV commands the lesser of constraint speed or present performance speed.
Speed and/or altitude display in magenta when they are the FMC target values.
Displays the reference vertical bearing waypoint identifier and altitude.
Displays pilot entered waypoint/altitude data if entered.
Defaults to the next descent waypoint constraint (displayed in 1R) if no pilot entry.
For window altitude constraints, displays the upper altitude if the airplane is above
it, otherwise the lower altitude is displayed.
Displays dashes if no constraint exists in the descent portion of the flight plan.
