Push Line Select key 1 and observe SPD and SEL alternately flashing in Data Line 1 and desired speed now displayed. Push Line Select key 1 again to command new speed.
Note: Speed or Mach may be edited at any time. The CRZ (NON OPT) can thus be armed for entry at transition to CRZ.
After speed edit, the remaining page data is for the edited speed. Display changes from speed to Mach at leading digit of speed entry as follows:
5 or Less – IAH 5 or More – MACH If leading decimal is used, any legal Mach entry will be accepted by the system. To return to the CRZ OPT page:
Slew Switch .......................................................................................PUSH
Push SLEW switch in either direction until the CRZ OPT page is displayed. Observe Line Select key 1 is illuminated and SPD and SEL are alternately flashing in Data Line 1.
Line Select Key 1 ..............................................................................PUSH
Push Line Select key 1 to command CRZ OPT mode.
Note: CRZ OPT can also be obtained from the CRZ (NON OPT) page by pushing the CLEAR key and then pushing Line Select key 1 twice.

HOLD / ENDUR
Note: HOLD / ENDUR mode and display is a cruise mode where speed is controlled to a minimum fuel flow as computed for current conditions.
HOLD ./ ENDUR speed is based on one of the two airplane
configurations:
.
Clean.
.
Slats extended, flaps zero.
This speed is limited to VMAX / VMIN which will consider current flap extension.
If HOLD / ENDUR mode is desired:
Note: If not on a CRUISE page, push the CRZ key to obtain a CRUISE page before starting procedure.
Slew Switch .......................................................................................PUSH
Push SLEW switch in either direction until HOLD / ENDUR page is displayed. Observe that Line Select key 1 is illuminated and SPD and SEL are alternately flashing in Data Line 1.
Line Select Key 1 ..............................................................................PUSH
Push Line Select key 1 to command mode. To return to CRZ OPT page:
Slew Switch .......................................................................................PUSH
Push SLEW switch in either direction until the CRZ OPT page is displayed. Observe Line Select key 1 is illuminated and SPD and SEL are alternately flashing in Data Line 1.
Line Select Key 1 ..............................................................................PUSH
Push Line Select key 1 to command CRZ OPT mode.
During cruise, 5 minutes before computed top of descent, the PLAN page with the message DIST TO BOD? is automatically displayed.
Caution: Prior to initiating a descent under PMS control, it is essential that the distance to BOD be confirmed. Errors in distance to BOD can be caused by diversions from the originally planned route of flight or drop outs by VOR / DME data to the PMS during flight.
(Continued)
The DIST TO BOD? scratchpad message must be cleared in accordance with one of the following methods:
.
If the BOD is defined relative to a VOR and bottom of descent distance displayed is less than 200 NM, verify that the BOD definition is correct, BOD VOR is tuned and that no VOR / DME flags are present.
.
Push CLEAR key to clear the DIST TO BOD? message.
Note: BOD distance displayed in this case will be the distance direct from present position to the BOD point.
.
In all other cases, BOD distance must be cross-checked against other navigation systems or charts. If displayed BOD distance is not correct, edit to correct values.
When BOD distance is correct, push the CLEAR key to clear the DIST TO BOD? message.
Note: After clearing the DIST TO BOD? message, the PMS will display the preselected DESCENT page. If a descent mode has not been selected, PMS will automatically display DES (NON OPT).
ARM ALT? will be displayed on scratchpad if a lower than cruise altitude is not selected and armed.
PLN CRZ W/V Page:
The PLN CRZ W/V page advises pilot of the characteristics of the cruise
wind model being used by the PMS, and will allow edits of model based on
pilots knowledge of winds above and below airplane’s current altitude.
Note: Based on pilot inputs, PMS will compute a modified optimum altitude. This page is available only in cruise at a PLAN altitude. If PLAN CRZ W/V page is desired:
PLAN Key.........................................................................................PUSH
Push PLAN key and observe PLAN page is displayed. Slew up or down until PLN CRZ W/V page is displayed. Observe Data Line 2 displays current measured wind direction, speed and component of that wind along airplane heading. 中國航空網 m.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：MD-80 Flight Manual 麥道80飛行手冊 2(154)
