PMS CLIMB
Initial selection and entry into a PMS climb mode can only be completed after the following conditions have been satisfied:
.
Climb vertical speed greater than 240 FPM (CLB annunciator illuminated), and selected altitude above current altitude.
.
TRI not in takeoff or go-around.
.
Either FD or AP engaged.
.
PMS valid.
.
Autothrottle engaged.
Note: All these conditions are normally satisfied during takeoff at 1000 ft. AGL when climb power is set. PMS should normally be engaged after clean-up and acceleration.
PERF Button.....................................................................................PUSH
Push the PERF button and observe that autothrottle and pitch FMA’s
display PERF CLB.
When transitioning from PERF CRUZ to CLB and a higher altitude has been armed (observe auto-selection of CLB OPT page and illumination of Line Select key 1 with SPD and SEL alternatively flashing in data line 1).
Note: PERF modes are disconnected whenever any other DFGS pitch axis mode is selected, or whenever another autothrottle mode is selected, or whenever flap position exceeds approximately 26° extended, or whenever PMS is invalid or whenever T.O. or TO FLX is selected on TRI.
Line Select Key 1 ..............................................................................PUSH
Push Line Select key 1 to engage CLB OPT mode.
Note: When transitioning from CRZ (NON OPT) to CLB OPT, a short duration speed bug transient may occur.
If an altitude is armed above planned altitude, altitude on PLAN CRZ page will change to agree with armed altitude.
If the 250 knot speed restriction is displayed in data line 1, speed bug will be at 250. However, PMS will control the autothrottles and FAST / SLOW indicator will center at 2.5 knots below the 250 knot restriction.

Rev. 12/01/00 #29 Flight Manual
The 250 knot vertical event for climb is displayed in Data Line
3.
Bracketed quantity indicates speed restriction is in effect. To clear the (250) knot speed restriction:
CLEAR Key......................................................................................PUSH
Line Select Key 1 Or 2......................................................................PUSH
Note: If Line Select key 1 was pushed, observe Line Select key 1 illuminated with SPD and SEL alternately flashing and unrestricted speed displayed in Data Line 1.
If Line Select key 3 was pushed, observe Data Line 3 display flashing between CLEAR and current display.
Line Select Key 1 Or 3......................................................................PUSH
Push Line Select key 1 or 3 (same key as used in the preceding step). Observe removal of restriction with the new speed displayed in Data Line 1.
Note: Removal of speed restrictions can also be obtained by calling up the vertical waypoint BOD page and editing CLEAR in the line where restriction is displayed.
At altitudes of 27,000 feet or above, SPD is displayed as a Mach number.
If a climb other than CLB OPT is desired:
CLB (NON-OPT)
Desired Speed...........................................ENTER INTO SCRATCHPAD
Enter desired speed into scratchpad using the data entry keys.
Note: Display changes from speed (SPD) to Mach (M.) at leading digit
of speed entry as follows:
1 through 4 – IAS
5 through 9 – MACH
If leading decimal is used, any Mach entry that does not exceed the limit speeds will be accepted by the system.
(Continued)
Line Select Key 1 ..............................................................................PUSH
Push Line Select key 1 and observe it is illuminated with SPD and SEL alternately flashing in Data Line 1 and page title changed to CLB (NON OPT). Push Line Select key 1 again to engage mode.
Note: Further edits may be made to change speed as required.
CLB OPT page can be recalled by slewing on this page and
pushing Line Select key 1 or editing CLEAR on line 1.
CLB MAX
Slew Switch .......................................................................................PUSH
Push SLEW switch in either direction until CLB MAX page is displayed. Observe Line Select key 1 is illuminated and SPD and SEL alternately flashing in Data Line 1.
Line Select Key 1 ..............................................................................PUSH
Push Line Select key 1 to engage mode.
Note: IAS / MACH is computed by system for maximum angle of climb. CLB MAX speed is the higher of 1.5 VS for a clean airplane or 1.3g buffet (low).
