• XXXKT – fixed CAS climb speed profile
• M.XXX – fixed Mach climb speed profile
• ACT – displays prefix when climb phase active.
• MOD – displays prefix in shaded white text when a modification is
pending.
Fixed climb speeds are for:
• takeoff/climb acceleration segment constraints
• waypoint speed constraints
• a speed constraint associated with an altitude
• a speed transition
• a flight crew selected speed (SEL SPD).
Displays altitude or airspeed/altitude constraint at waypoint XXXXX.
Can also display HOLD AT XXXXX followed by a speed/altitude constraint.
FMC commands the slower of constraint speed or performance speed.
Constraints are entered on RTE LEGS page.
Delete here or on RTE LEGS page.
Blank if no constraint exists.
Magenta when it is FMC command speed or altitude.
Displays altitude discrepancy and distance past waypoint where altitude will be
reached.
Blank if no error exists.
Transition altitude for origin airport contained in navigation database. FMC uses
18,000 feet if transition altitude is not available.
Manually change transition altitude here or on DESCENT FORECAST page.
Valid entries are XXX, XXXX, XXXXX, or FLXXX.
CDU altitude data change from altitudes to flight levels above the transition
altitude.
Displays maximum angle of climb speed.
Push – displays speed in the scratchpad for pilot selection to the speed line.

Push (below speed transition or restriction altitude) –
• displays MOD EO CLB page
• deletes climb speed transition or restriction data
Push (below engine-out maximum altitude) – displays MOD EO CLB page.
Push (above engine-out maximum altitude) –
• displays MOD EO D/D or MOD EO LRC D/D page
• cruise altitude (1L) lowered to engine-out maximum altitude if that
altitude is less than the active cruise altitude
Shaded white until the modification executed. Upon execution, thrust reference
limit becomes CON in all cases above.
Displays when climb altitude constraint exists between current altitude and FMC
cruise altitude.
Push – deletes all waypoint altitude constraints between the airplane altitude and
the MCP altitude or FMC cruise altitude, whichever is lower. FMC cruise altitude
is not affected.

RTE X LEGS Page
Leg segment data in line title:
• courses – magnetic (xxx°) or true (xxx° T)
• arcs – distance in miles, ARC, turn direction (example: 24 ARC L)
• heading leg segments – xxx° HDG or xxx° THDG (when referenced to
true north)
• track leg segments – xxx° TRK or xxx° TTRK (when referenced to true
north)
• special procedural instructions from database - HOLD AT, PROC TURN,
or PROC HOLD (FMC exits hold when crossing the fix after entry).
Calculated great circle route leg directions may be different than chart values.
