MN-FLT-OH-201
During active cruise, entry of a new value propagates to all other pages which
display cruise altitude and causes the MOD CRZ CLB or MOD CRZ DES page
to appear.
Value may be increased or decreased using altitude intervention.
2
Target Speed (TGT SPD)
The computed target speed displays one of the following:
• computed or manually selected value for target airspeed or Mach
• XXX/MCP when speed intervention is active and the plan is active
•deletion or modification of XXX/MCP is not allowed
• XXX/HOLD when decelerating to hold speed prior to the hold entry fix
•deletion or modification of hold speed is not allowed.
The value is reverse highlighted on an active cruise page.
Target Speed that would normally be displayed as “highlighted” for a non-color
application, is displayed in magenta for color CDU’s on an active cruise page.
3
Turbulence N1 (TURB N1)
Displays proper N1 for turbulence penetration.
Value is for reference only. It is not commanded to the autothrottle.
4
Fuel at Destination (FUEL AT XXXX)
Displays the predicted fuel remaining at destination.
The value assumes continued flight per the displayed cruise and planned descent
modes along the active route.
If a step to altitude is entered on line 1R, the computation assumes that the step
will occur at the step point. After passing the step climb point, the predicted fuel
weight is based on an immediate step climb from current position.
5
Cruise Page Prompts
Allow line selection of the various cruise pages.
The RTA prompt is replaced with ERASE when a MOD page is displayed.
6
Optimum/Maximum Altitude (OPT/MAX)
Displays the computed optimum altitude for the displayed cruise mode. The value
is not constrained by minimum cruise time criteria (as is the TRIP ALT on the
PERF INIT page).
Also displays the maximum possible altitude based on the selected target speed
and the specified maneuver margin.
