a Title line : the right corner of the line indicates how

_ many routes have been stored by the pilot and which one is displayed. Slew key actions display the previous or next company route.
 b Lines 1L through 5L display the same data as described in
_ ROUTE page.
 c Field 6L : The DELETE ALL prompt has the same functionality
_ as the prompt described for STORED NAVAID page. If all stored routes are deleted, the display changes to the NEW NAVAID page. If one route is used as active, temporary or secondary flight plan, it is not deleted.
 d Field 6R : It allows the pilot to have access to the NEW
_ ROUTE page.
The pilot may create a new company route and store it. He may have access to the NEW ROUTE page

 STORED ROUTE Page
 Figure 062

 (Ref. Fig. 063)
 from the DATA INDEX page (stored route prompt and no stored
 route exists) or from the stored route page.
 Data fields:

 a_ Line 1L : The pilot can enter a new company route number.
 If the pilot does not enter a company route number, the new
 route (if stored) is named SRTE N (N is a number : 1 to 3).
 If the pilot enters an existing number, the entry is
 rejected.

 b Line 2L : It permits to store elements (lateral elements
_ plus cost index - cruise flight level and step (if any)) from the active flight plan into the new route. The display changes to stored route page with the newly entered route.
 c Line 2L : Same as 1L but with storage of secondary flight
_ plan elements into the new route.
 d If three routes have already been defined, the pilot may
_ not store a new one.
 (i)
 Alternate Up to 6 alternates may be defined for a given airport, but one must be designated as the preferred alternate. The alternate is an airport or company route. The alternate information consist of a list of alternates and the alternate airway distance associated with each.

 Fuel policy Each navigation data base contains eight fuel policy files. A set of fuel parameters contained in each fuel policy are selected via airline program pin and used in performance fuel computations.

 NEW ROUTE Page
 Figure 063

 Each fuel policy consists of the following fuel parameters:

 ------------------------------------------------------------------------| MNEMONIC | PARAMETERS | VALUES | |-----------------|--------------------------------|-------------------| | RTE RSV | - Percentage of route reserve | decimal | |-----------------|--------------------------------|-------------------| | RSV MIN | Minimum value of route reserve | decimal | |-----------------|--------------------------------|-------------------| | RSV MAX | Maximum value of route reserve | decimal | |-----------------|--------------------------------|-------------------| | RSV FL | Reserves are computed for fuel | Y/N | | | predictions in flight | | |-----------------|--------------------------------|-------------------| | RSV ALTN | Reserve includes reserve of | Y/N | | | alternate trip | | |-----------------|--------------------------------|-------------------| | FINAL TF | Final time used for fuel | decimal | | | prediction computation | | |-----------------|--------------------------------|-------------------| | FINAL FIXF | Inclusive final fuel used for | decimal | | | fuel prediction computation | | |-----------------|--------------------------------|-------------------| | FINAL ALT | Altitude of the holding | 1 500 ft. | | | pattern which the final | 20,000 ft. | | | computation is based on | | |-----------------|--------------------------------|-------------------| | TAXI | Taxi fuel | decimal | |-----------------|--------------------------------|-------------------| | FINAL DEST | Airport upon which the final | Primary/ | | | fuel computation is performed | Alternate | ------------------------------------------------------------------------
All these values are displayed on the Init page B (which has been
 shown in chapter 71-3 about initialization).
 For the records in which data is not provided, default value for
 the corresponding parameter is defined in the following list:

 -Taxi = 200 kg
 -RTE RSV = 5%
 -
RSV MAX = 10,000 kg

 -
RSV MIN = 0 kg

 -
RSV FL = Y

 -
RSV ALTN = N

 -
FINAL TF = 30 min

 -
FINAL FIX F = 0 kg

 -
FINAL ALT = 1500 ft.

 -
FINAL DEST = A

 F. Performance Data Base The performance data base is the data stored for the performance models. This data base is composed of tables and equations for computing the aircraft aerodynamic and engine models. Access to the performance data base is achieved by the performance process which uses the data for predictions and optimizations. Two types of model are described in the performance data base relating to:
