Cruise Altitude (CRZ ALT)
Initially displays the CRZ ALT entered on the CRZ page.
Manual entry may be made.
Target Speed (TGT SPD)
Displays target cruise speed for the displayed cruise altitude.
Manual entry may be made.
TO FLXXX
Displays ETA at, and distance to, the displayed cruise altitude.
Planned Descent (PLANNED DES)
Shows the planned DES page and allows access to the planned standard descent mode.
RTA Cruise Descent (U4 and on)
The RTA CRZ DES page displays the same data as the CRZ DES page except for the TIME ERROR line.
Flight Management, Navigation -FMC Cruise 737 Operations Manual
TIME ERROR
Displays the computed time error at the RTA waypoint.
Same as time error on RTA PROGRESS page.
Engine Out Cruise
The engine out cruise page may be accessed by selecting the ENG OUT prompt on the CRZ page. The page displays advisory information for a one engine inoperative condition. Engine out data is also available with both engines operating.
(U5 and on) The FMC accounts for current gross weight and actual bleed conditions.
(U3 and U4) The FMC accounts for:
.
current gross weight
.
wing and engine anti–ice OFF
.
air conditioning pack switches AUTO above 17,000 feet
.
engine bleed air switches OFF below 17,000 feet.
(Prior to U7.5) When activated, all subsequent performance predictions are blanked and VNAV cannot be engaged.

Engine Out (ENG OUT)
Permits access to ENG OUT CRZ page.
Left/Right Engine Out (LT ENG OUT/RT ENG OUT)
Selection changes display to MOD ENG OUT CRZ page. The MOD ENG OUT
CRZ page is information only.
(U7.5 and on) The execute light does not illuminate and the page can not be
executed.
(Prior to U10) After viewing page data, select ERASE to return to the active CRZ
page.
Target Speed (TGT SPD)
Displays the optimum speed based on minimum drag.
N1
Displays N1 for maximum continuous thrust.

Flight Management, Navigation -FMC Cruise
(Prior to U7.5) If the page is executed, this becomes the active N1 limit. N1 is computed using actual bleed conditions.
Maximum Altitude (MAX ALT)
Displays the computed maximum altitude at which a company–specified rate of climb can be achieved, using one engine at maximum continuous thrust. Default climb rate is 100 feet per minute.
Left/Right Engine Out (LT ENG OUT / RT ENG OUT)
Selected engine out is shown in reverse highlighting.
Early Descent
Early descents are initiated from the DES page. Once an early descent is executed, VNAV transitions to the descent mode, and cruise features are no longer available.
For a VNAV path descent (prior to U10) the CAPTURE or (U10) the DES NOW prompt will not be displayed until a descent path is established. Once executed, the autothrottle adjusts thrust to maintain 1,000 feet per minute until intercepting the descent path.
For a VNAV speed descent, the autothrottle retards to idle, and pitch maintains target speed.

CAPTURE/DES NOW
Selecting the PATH DES page before reaching the top of descent displays the PATH DES page (prior to U10) with the CAPTURE or (U10) with the DES NOW prompt on the bottom right of the page. Selecting and executing the CAPTURE/DES NOW prompt initiates a VNAV descent of 1000 feet per minute at ECON speed. Upon reaching the planned descent path, VNAV transitions to maintain the planned descent path.
Selecting the SPD DES page and executing the CAPTURE/DES NOW prompt initiates a VNAV descent at idle thrust and target speed. (U3 and U4) This is the only way to begin a speed descent.

Route and Waypoint Data Route Data (RTE DATA) Page
The RTE DATA page displays ETAs for each waypoint on the RTE LEGS page.
This page also displays forecast wind data for cruise waypoints.
One page displays data for five waypoints.
Waypoint
Displays the same waypoint identifier as on the corresponding RTE LEGS page.
