The altitude can be changed by two methods:
• a new cruise altitude can be manually entered from the CDU at any time.
The modified cruise altitude displays in shaded white until executed
• a new cruise altitude can be entered from the MCP, if intermediate altitude
constraints do not exist between the airplane altitude and the MCP altitude.
Set cruise altitude in the altitude window and push the altitude selector.
The cruise altitude changes without modification or execution
ECON SPD:
• speed based on cost index in CAS or Mach
• used by FMC at altitudes above all waypoint speed constraints, speed
restrictions, and speed transition altitudes
Valid entries are CAS or Mach.
SEL SPD:
• displays when intermediate level off required below an existing speed
constraint
• displays when flight crew enters speed
Valid entries are CAS or Mach.
The FMC commanded speed is magenta. Below CAS/Mach transition altitude,
CAS is magenta and Mach is white. Above CAS/Mach transition altitude, Mach
is magenta and CAS is white.
The speed transition line displays the transition speed/altitude from one of these
sources:
• the navigation database value for the origin airport
• the value specified from the airline policy page
• the greater of the transition speed associated with the origin airport or
VREF+80 knots (example 250/10000)
Magenta when it is FMC command speed.
Not displayed above transition.
Can be deleted.
Speed restrictions for an altitude less than the cruise altitude are manually entered
on this line.
Dashes before entry by flight crew.
Valid entry is a CAS and altitude (example 240/8000).
An entry creates a modification. Entry is shaded white until executed; magenta
when it is FMC command speed.
