BUILD/MODIFY FLIGHT PLANS PROCEDURES
The following paragraphs contain the build/modify flight plans procedures listed below:
• Waypoint entry rules
• Build new flight plan
• Change flight plan name
• Delete waypoint from flight plan
• Replace waypoint in flight plan
• Insert waypoint in flight plan Waypoint Entry Rules.
When building or modifying a flight plan, waypoints can be se-lected by using one of the following Waypoint Search Proce-dures described above:
a. Using Waypoint Number or Mark Point Letter proce-dure or,
b. Using Waypoint Identifier procedure.
Build New Flight Plan.
To build a new flight plan, proceed as follows:
a. CDU - Depress FPM function select key. Observe FP-MENU Page(s) (Figure 1-67) is displayed.
b. CDU - Enter name of new flight plan in scratchpad.
c. CDU - FPMENU Page - Depress name new flight plan LSK. [This is the LSK next to the brackets symbol and the (NEW FP) field.] Observe the following:
(1) FPBUILD Page (Figure 1-68) for building new flight plan is displayed. Brackets symbol, 01, and NEXT displayed in fields associated with second LSKs.
(2) Scratchpad is cleared.
NOTE
(4) (NEW FP) is displayed to the right of the next available flight plan number which will have the brackets symbol to the left.
NOTE
•
If the flight plan database is full, the flight plan name field on the top of Page 6/6 will display (FULL), and the flight plan number and brackets will not be displayed.•
If the name new flight plan LSK is depressed with no name entered in the scratchpad, IN-PUT ERROR will be displayed in the scratch until the CLR pushbutton on the CDU is de-pressed.d. To enter waypoints into the new flight plan, on FP-BUILD Page, proceed as follows:
(1) Using Waypoint Search Procedures (Using Waypoint Number or Mark Point Letter or Using Waypoint Identifier) enter, in the scratch-pad, the waypoint information for first waypoint in the flight plan.
(2) Depress waypoint LSK to the left 01. Observe the following:
(a) Entered waypoint identifier is displayed to the right of 01.
(b) An arrow symbol is displayed to the left of the branch to waypoint attributes (WP-TATT) LSK.
(c) Brackets symbol, 02, and NEXT are dis-played in next available waypoint fields.
(3) Repeat Step d.(1) and Step d.(2) above until de-sired flight plan is completely entered.
NOTE
•
To assign or modify flight plan specific attributes to a waypoint, depress the WP-TATT LSK associated with the desired way-point. Use WPTATT Page (Figure 1-69) toChange Flight Plan Name.
To change a flight plan name, proceed as follows:
a. CDU - Depress FPM function select key. Observe FP-MENU Page (Figure 1-67) is displayed.
b. CDU - Use P/G rocker switch, if necessary, to page down (or up) until desired flight plan number and name are visible on page.
c. CDU - FPMENU Page - Depress branch to FPBUILD Page LSK associated with flight plan whose name is to be changed. Observe desired FPBUILD Page (Figure 1-68) is displayed.
d. CDU - Ensure scratchpad is cleared. Depress CLR pushbutton, if necessary.
NOTE
The flight plan name LSK will be inactive (no target symbol displayed) if data is displayed in the scratchpad at this time.
e. CDU - FPBUILD Page - Depress flight plan name (NM:) LSK. Observe the following:
(1) Flight plan name field next NM: is cleared.
(2) Flight plan name is displayed in the scratchpad.
(3) Target symbol next NM: changes to brackets symbol.
NOTE
Waypoint search function is disabled at this time.
f. CDU - Edit/change flight plan name in scratchpad.
g. CDU - FPBUILD Page - Depress flight plan name (NM:) LSK. Observe the following:
(1) Scratchpad is cleared.
(2) Edited/changed flight name appears in the flight plan name field next NM.
(3) Brackets symbol next to NM: changes to target symbol.
•
The updated flight plan is automatically writ-ten to the DTS, when another CDU display page other than the FPMENU, FPBUILD, or WPTATT Page is selected.Delete Waypoint From Flight Plan.
To delete a waypoint from a flight plan, proceed as follows:
NOTE
A flight plan with only one waypoint (leg), or the last waypoint of any flight plan cannot be deleted.
a. CDU - Depress FPM function select key. Observe FP-MENU Page (Figure 1-67) is displayed.
b. CDU - Use P/G rocker switch, if necessary, to page down (or up) until desired flight plan number and name are visible.
c. CDU - FPMENU Page - Depress branch to FPBUILD Page LSK associated with flight plan that is to be changed. Observe desired FPBUILD Page (Figure 1-68) is displayed.
d. CDU - Use P/G rocker switch, if necessary, to page down (or up) until waypoint to be deleted is visible on page.
e. CDU - FPBUILD Page - Depress waypoint LSK next to waypoint sequence number of waypoint to be deleted.
Observe the selected waypoint number appears in the scratchpad. CDU - Depress CLR pushbutton. UFC - De-press CLR pushbutton and hold. Observe the following:
(1) Selected waypoint is removed from flight plan.
(2) All subsequent waypoints move up by one and their waypoint sequence numbers are decre-mented by one.
(3) Scratchpad is cleared.
NOTE
The updated flight plan is automatically written to the DTS, when another CDU display page other than the FPMENU, FPBUILD, or WP-TATT Page is selected.
Replace Waypoint In Flight Plan.
To replace a waypoint in a flight plan, proceed as follows:
a. CDU - Depress FPM function select key. Observe FP-MENU Page (Figure 1-67) is displayed.
b. CDU - Use P/G rocker switch, if necessary, to page down (or up) until desired flight plan number and name are visible on page.
c. CDU - FPMENU Page - Depress branch to FPBUILD Page LSK associated with flight plan that is to be changed. Observe desired FPBUILD Page (Figure 1-68) is displayed.
d. CDU - Use P/G rocker switch, if necessary, to page down (or up) until waypoint to be replaced is visible on page.
e. CDU - FPBUILD Page - Using Waypoint Search Pro-cedures (Using Waypoint Number or Mark Point Letter or Using Waypoint Identifier) enter, in the scratchpad, the waypoint information for the replacement waypoint in the flight plan.
f. CDU - FPBUILD Page - Depress the waypoint LSK to the left of the waypoint to be replaced. Observe that waypoint selected in above step replaces the waypoint associated with the LSK that was depressed.
NOTE
•
To assign or modify flight plan specific at-tributes to the replacement waypoint, depress the WPTATT LSK associated with the de-sired waypoint. Use WPTATT Page (Figure 1-69) to change/modify flight plan specific attributes.•
The updated flight plan is automatically writ-ten to the DTS, when another CDU display page other than the FPMENU, FPBUILD, or WPTATT Page is selected.Insert Waypoint In Flight Plan.
To insert a waypoint into a flight plan, proceed as follows:
a. CDU - Depress FPM function select key. Observe FP-MENU Page (Figure 1-67) is displayed.
b. CDU - Use P/G rocker switch, if necessary, to page down (or up) until desired flight plan number and name are visible on page.
c. CDU - FPMENU Page - Depress branch to FPBUILD Page LSK associated with flight plan that is to be changed. Observe desired FPBUILD Page (Figure 1-68) is displayed.
d. CDU - FPBUILD Page - Depress INSERT LSK. Ob-serve the following:
(1) All waypoints move down one line so that they are positioned between LSKs.
(2) The branch to waypoint attributes (WPTATT) Page header is removed and the branch to way-point attributes (WPTATT) Page LSKs are inac-tive (arrow symbols removed).
e. CDU - Use P/G rocker switch, if necessary, to page down (or up) until waypoint below the point where the new waypoint is to be inserted is visible on page.
f. Using Waypoint Search Procedures (Using Waypoint Number or Mark Point Letter or Using Waypoint Iden-tifier) enter, in the scratchpad, the waypoint information for the waypoint to be inserted in the flight plan.
g. CDU - FPBUILD Page - Depress the waypoint LSK to the left of the where the new waypoint is to be inserted.
Observe the following:
(1) Observe that waypoint selected in above Step g is inserted in the desired position.
(2) The waypoint sequence numbers of all way-points following the inserted waypoint are in-cremented by one.
(3) The waypoints are all properly aligned with their LSKs.
(4) The branch to waypoint attributes (WPTATT) Page header reappears and the branch to way-point attributes (WPTATT) Page LSKs are ac-tive (arrow symbols displayed).
