Note:  No edits are allowed on Data Line 2.
Data Lines 1 and 3 respectively default to altitudes 4000 ft above and below the current cruise altitude with zero wind shear in that altitude band.
When loading data into lines 1 and 3, both wind angle and speed must be entered at the same time.
If default altitudes are to be used, it is not necessary to load altitude into PMS.
To enter winds on PLN CRZ W/V page:
Altitude (If Applicable) /
Direction / Speed......................................ENTER INTO SCRATCHPAD

Enter altitude (if other that a default altitude), / , direction, / , and speed of wind into scratchpad. Push Line Select key 1 or 3 to enter data on corresponding data line. To enter second wind, repeat above step entering data on remaining Data Line by using appropriate Line Select key.
Note:  After an edit has been made, the edited line and optimum altitude display are bracketed to indicate that each is resultant of an edit.
Bracketed optimum altitude will also appear on all other pages where optimum altitude is normally displayed.
Wind direction and speed edits will be dashed if the data line 2 component changes by more than 20 knots due to a wind change or a turn to a new heading.
To clear a previous edit:
CLEAR Key / Line Select Key ........................................... PUSH / PUSH

Push CLEAR key and then push appropriate Line Select key. Observe that Data Line has reverted to default altitude and direction and speed of wind are now dashed.
Cruise Altitude / Distance Inquiry:
The altitude / distance inquiry procedure is valid only from present position on the profile to the next top of climb (TOC) point. Editing of an altitude below current altitude will result in a CHECK ENTRY message. Editing of an altitude or distance beyond the next TOC point will be accepted in Line 3, but the remainder of the parameters will be dashed.
(Continued)
Note:  This procedure will allow entry of an altitude of distance in Data Line 3 of any CRUISE page (except when trim data is not loaded), thus creating a new vertical event called ALT, with its corresponding altitude / distance / time data.
If an altitude / distance inquiry is desired:
Note:  A CRUISE page must be displayed in order to make an altitude / distance inquiry. If not on a CRUISE page, page the CRZ key and observe that the engaged mode is displayed.
Altitude Inquiry
Altitude Desired .......................................ENTER INTO SCRATCHPAD

Enter desired altitude into scratchpad using the data entry keys.
Line Select Key 3 ..............................................................................PUSH

Push Line Select key and observe data is now displayed on Data Line 3.
Note:  The distance and time in Data Line 3 will now decrement until desired altitude is reached. Then Data Line 3 will change to display next vertical event.
Distance Inquiry
Distance Inquiry.......................................ENTER INTO SCRATCHPAD

Enter desired altitude into scratchpad using the data entry keys.
Line Select Key 3 ..............................................................................PUSH

Push Line Select key 3 and observe data is now displayed in Data Line 3.
Note:  The altitude and time now correspond to the desired distance. Distance and time also decrement for this edit case. Altitude will vary slightly but will always be that projected to be reached in the displayed distance and time.
Distance inquires are limited to 999 NM.

PMS CRUISE (TRIP DATA NOT ENTERED)

CRZ (NON OPT) mode, without profile related data, is the only available mode during cruise.
Note:  Speed editing is the only operation that can be performed on this page.
To initiate a speed change:
Desired Speed...........................................ENTER INTO SCRATCHPAD

Enter desired speed into scratchpad using the data entry keys.
Line Select Key 1 ..............................................................................PUSH

Push Line Select key 1 and observe desired SPD now displayed in Data Line 1 with SPD and SEL alternately flashing and Line Select key 1 is now illuminated. Push Line Select key 1 again to command new speed.
Note:  Thrust target is dashed (EPR ---) when mode is not engaged.
PMS DESCENT

Initial selection and entry into a PMS descent mode can only be completed after the following conditions have been satisfied:
.  
Descent vertical speed greater than 240 feet per minute (DES annunciator illuminated) and selected altitude below current altitude.

.  
TRI not in takeoff or go-around.

.  
Either FD or AP engaged.
