Select the “Maintain Aircraft Routing” link under the “Flight Assignment” business component.

The “Maintain Aircraft Routing” page appears.

The system displays the following:

Date Format

The format in which the date field is to be entered. This format is displayed from the "User Preferences" business component based on the login user ID. In case the format is not defined, the system displays the date format from the “Enterprise Modeling” business component by default.

Enter the following in the “Search Criteria” group box:

Display Options	Use the drop-down list box to select one of the following display options: By Flight Schedule # - Select this option to retrieve the aircraft routing details based on the flight schedule number. By Flight # - Select this option to retrieve the aircraft routing details based on the flight code. By default, the system sets the field to “By Flight #”.
Planning Region	Use the drop-down list box to specify the region for planning the aircraft routing. The system lists all the active regions that are defined in the “Maintain Region” activity in the “Common Masters” business component. By default, the system sets the field to the region to which the login user is mapped. The system retrieves the aircraft routing plan for the planning region specified here.
Flight Schedule #	The flight schedule number for which the routing details are to be retrieved (Alphanumeric, 24). You can enter the flight schedule number in full or specify it partially using the “*” character. The system retrieves the aircraft routing plan defined for flight schedule number entered here.
Trip #	The number identifying the trip in the journey (Alphanumeric, 150). You can enter the trip number in full or specify it partially using the “*” character. The system retrieves the aircraft routing plan for the trip number entered here.
Flight #	The number identifying the flight for which routing details are to be retrieved (Alphanumeric, 30). You can enter the flight number in full or specify it partially using the “*” character. The system retrieves the aircraft routing plan for the flight number specified here.

Note: If the “Display Options” is set as “Flight Schedule #”, the system retrieves the routing details for the flight number specified here, only if the flight code falls within the flight schedule applicable for the specified date range.

Leg #	The number identifying the leg in the journey (Integer). You can enter the leg number in full or specify it partially using the *” character. The system retrieves the aircraft routing plan for the flight and leg number combination specified here.
Aircraft Reg #	The registration number of the aircraft for which routing details are to be retrieved (Alphanumeric, 30). You can enter the aircraft registration number in full or specify it partially using the “*” character. The system retrieves the aircraft routing plan for the aircraft registration number specified here.
From Station	Use the drop-down list box to select the starting station of the flight. The system lists all the “Active” stations defined in the “Create Station” activity of the “Common Masters” business component. The system leaves this field blank by default.
To Station	Use the drop-down list box to select the destination station of the flight. The system lists all the stations defined in the “Create Station“ activity of the “Common Masters” business component and leaves the field blank by default.
Routing From Date	The date starting from which the routing details are to be retrieved (Date Format). The system retrieves the aircraft routing plan for which the effective start date is on or later than the date specified here. The system displays the current server date by default.
Routing To Date	The date till which the routing details are to be retrieved (Date Format). The system retrieves the aircraft routing plan for which the effective end date is on or earlier than the date specified here. The date entered here must be later than the date entered in the “Routing From Date” field. By default, the system displays a date, by adding the “Routing From Date” and the “Aircraft Routing Planning Horizon” set in the “Set Options” activity.

Click the “Get Details” pushbutton to retrieve the aircraft routing details, if any.

If the “Display Options” is set as “By Flight Schedule #”, the system retrieves all the flight schedules that are active and applicable for the date range defined by the “Routing From Date” and “Routing To Date”.

If routing plan is already defined for the flight code or flight code and leg number combination or flight schedule number and trip number, the system retrieves the details of the flight code and leg number that are part of the flight schedule, along with the assigned “Aircraft Reg #”, “From Date” and “To Date”.

If the “Display Options” is set as “By Flight #”, the system retrieves the details of all the active flight codes with status as “Operative”. If routing plan is already defined for the flight code, the system retrieves the details of the associated “Aircraft Reg #”, “From Date” and “To Date”.

To view routing plan details

In the “Routing Plan” group box, the system displays the “Gantt Chart” depicting the routing plan details.

The system displays the details of all the flights that are scheduled between the dates specified in the “Routing From Date” and “Routing To Date” fields.

For the given “Routing From Date” and “Routing To Date”, the system displays all the applicable flight codes along the Y-axis of the chart, and the dates between the Routing From Date and Routing To Date along the X-axis.

If a “Flight Schedule #” alone is entered, the system displays the flights applicable for the given flight schedule number. If both the “Flight Schedule #” and the ”Trip #” are entered, then the system retrieves only those flight codes which are applicable for the corresponding “Flight Schedule #” and “Trip #” combination.

To define or modify aircraft routing details

Modify the following in the “Aircraft Routing Details” multiline, if required:

Flight #	The number identifying the flight, for which routing has to be defined or updated (Alphanumeric, 30).
Leg #	The number identifying the leg in the journey (Integer).
Aircraft Reg #	The registration number of the aircraft to be assigned to the flight (Alphanumeric, 30). Mandatory. The aircraft registration number must have been defined in the “Create Aircraft Information” activity of the “Aircraft” business component and the record status must be “Active”.
From Date	The date starting from which aircraft routing must be defined for the flight (Date Format). Mandatory.
To Date	The date till which aircraft routing must be defined for the flight (Date Format). Mandatory. The date entered here must be later than the date specified in the “From Date” field and the current system date.
Flight Schedule #	The number identifying the flight schedule for which routing has to be defined or updated (Alphanumeric, 24).

Note: If both “Flight #” and “Flight Schedule #” are specified, ensure that the “Flight #” is defined for the specified flight schedule in the “Flight Assignment” business component.

Also, ensure that the date range specified for routing, does not overlap for the same flight number or flight schedule number specified in the multiline.

Trip #

The number identifying the trip, applicable for the flight code or the flight schedule (Alphanumeric, 150).

Note: You cannot modify the routing details that are retrieved in the multiline.

Enter the following in the “Edit Routing Options” group box, if you wish to reassign the aircraft registration number of the flight with new aircraft registration number:

Replacement Aircraft Reg #

The new aircraft registration number that is to be assigned to the flight (Alphanumeric, 30). The aircraft registration number must have been defined in the “Create Aircraft Information” activity of the “Aircraft” business component and the record status must be “Active”.

Note: If the “Replacement Aircraft Reg #” is entered, ensure that at least one record is selected in the multiline.

Replacement Type

Use the drop-down list box to specify the replacement type of the aircraft. The system lists the following options:

“Reassign” – Select this option if you wish to modify the assignment of aircraft registration number to the flight.
“Unassign” – Select this option if you wish to remove the assignment of the aircraft registration number to the flight.

The system leaves this field blank by default.

Note: If the “Replacement Type” is set to “Reassign”, ensure that “Replacement Aircraft Reg #” and “Aircraft Reg #” are entered.

Also, ensure that the “Replacement Aircraft Reg #” is not assigned to any other flight and leg number combination, for the routing period.

If the “Replacement Type” is set to “Unassign”, ensure that “Aircraft Reg #” is entered.

From Date	The date starting from which the replacement of the aircraft registration number is to be done (Date Format). Data entry in this field is mandatory if replacement type is set as “Reassign” or “Unassign”.
To Date	The date till which the replacement of the aircraft registration number is to be done (Date Format). The date entered here must be later than the date specified in the “From Date” field and the current system date. Data entry in this field is mandatory if replacement type is set as “Reassign” or “Unassign”.

Check the box in the Select column of the multiline, to mark the aircraft registration numbers for replacement.
Click the “Maintain Aircraft Routing” pushbutton to update the aircraft routing details.

Note: Ensure that the aircraft registration number is not assigned to any other flight and leg number combination, for the given routing period.

The system assigns the aircraft registration number to the given flight schedule number and flight code, or for the flight and leg number, or for the flight number, for the scheduled dates, based on the schedule option set in the “Create Flight Schedule #” activity.

If the “Replacement Type” is set as “Reassign”, the system replaces the selected aircraft registration number(s) in the multiline with the “Replacement Aircraft Reg #” specified in the “Edit Routing Options” group box.

If the “Replacement Type” is set as “Unassign”, the system removes the selected aircraft registration numbers from the multiline.

Maintaining aircraft routing – An overview

This page allows you to define or modify the routing details for a flight and leg combination, at the flight code level or at the flight schedule level. You can assign aircraft registration numbers at flight code level to activate all the given flight codes for a selected routing period. Alternatively, you can assign the aircraft registration number at flight schedule level to activate the flight schedules, so as to operate all the flights that are part of the flight schedule with the same aircraft registration number.
