being computed and are displayed as ----. Move slew switch up or down
until PLAN-CRZ page is displayed.
Note: Data on PLAN CRZ page is not necessary for system engagement. If no data is entered, planned trajectory will be based on no altitude constraints, zero wind and standard day temperature.
CRZ Altitudes ..........................................ENTER INTO SCRATCHPAD
Enter CRZ altitudes (flight levels) into scratchpad. Push Line Select key 1 to transfer CRZ altitude(s) into Data Line 1.
Note: If an altitude is armed above the planned altitude but below maximum altitude (in flight), altitude will change on PLAN-CRZ page to agree with new armed altitude. If altitude above maximum is armed, the arm will be cancelled by the PMS approximately 2 seconds later. (Maximum altitude is gross weight dependent with an upper limit of 37,000 feet.)

Wind Component .....................................ENTER INTO SCRATCHPAD
Enter WIND COMPONENT into scratchpad (+ for tailwind, - for
headwind).
Note: A positive wind component entry does not require a + sign. However, for a negative wind component, first push the Alternate Function key, then the – key, then the WIND COMPONENT.
The loaded wind continues to be displayed and can be edited in flight. However, computations begin to use current wind when the first PLAN altitude is reached.
Push Line Select key 2 to transfer WIND COMPONENT to Data Line 2.
TEMP Or DEV ........................................ENTER INTO SCRATCHPAD
Enter TEMP at initial cruise altitude or the corresponding DEV (deviation from standard at initial flight level) preceded by a / to scratchpad. Push Line Select key 3 to enter TEMP or DEV into Data Line 3. In flight, this line changes to single engine maximum altitude with distance and time to that altitude.
Note: The loaded TEMP / DEV continues to be displayed and can be changed at any time before reaching 15,000 feet. Above 15,000 feet, editing of TEMP / DEV is inhibited and computations are based on current deviation.
In flight, the PLAN page TRIP distance changes to BOD / ALT.
GWT, FUEL and BOD distance display current data in flight. These parameters can be edited at any time.
Distance to BOD is entered TRIP distance minus 30 NM and BOD ALT is 10,000 feet. These are initial values and can be edited.
BOD definition is primarily used by the PMS to compute an initial flight profile. Further geographic definition of the BOD is done on EXPANDED BOD page.
If BOD is to be expanded further while on the PLAN page:
Line Select Or VERT WPTS Key ....................................................PUSH
Push Line Select key or VERT WPTS key and observe WPTS page is
displayed. Slew up until BOD line display comes into view.

Rev. 12/01/00 #29 Flight Manual
Line Select Key .................................................................................PUSH
Push Line Select key adjacent to BOD line display and observe PMS
displays WPT BOD* page.
Note: Data line of WPT BOD* page contained lateral position data of BOD, which can be defined as a VOR / DME, ILS / DME, VOR or ILS frequency / distance or a VOR frequency / radial / distance.
Lateral Position Data...............................ENTER INTO SCRATCHPAD
Enter lateral position data into scratchpad using data entry keys.
Note: A / must be inserted between a frequency and radial and between a radial and distance entry.
Line Select Key 1 ..............................................................................PUSH
Push Line Select key 1 and observe lateral position data is displayed in
data line one.
Note: Data line 2 defines desired speed / wind speed / wind direction at BOD. Any or all of these can be inserted, but if omitted, wind will default to zero and speed will be that used during descent if BOD is above 10,000 feet or 250 knots if BOD is 10,000 feet or lower.
Wind data can be loaded only after lateral position has been completely loaded and will default to zero if altitude definition is changed.
Speed / Wind Speed / Wind Direction.....ENTER INTO SCRATCHPAD
Enter speed, /, wind speed, /, wind direction into scratchpad using data
entry keys.
Note: Any speed above 130 knots can be loaded into system and PMS will compute a deceleration phase into profile.
Line Select Key 2 ..............................................................................PUSH
Push Line Select key 2 and observe speed / wind speed / wind direction
is displayed in data line 2.
(Continued)
Note: Data line 3 displays BOD distance and altitude. Distance and/or altitude on this line can be loaded at any time (in flight or on ground), except when within 200 NM of a BOD that is defined relative to a VOR / DME and that VOR / DME is tuned and being used for distance update. If an attempt to edit BOD distance is made under this condition, it will not be accepted and advisory message DISTANCE UP, DATING will be displayed.
