 (a)
 The SECONDARY flight plan vectors are transmitted for those legs which lie within the defined edit area.

 (b)
 The page displayed on the MCDU of the same side is a SECONDARY page.

 (c)
 The secondary flight plan is not identical to the ACTIVE flight plan within the defined edit area. If secondary flight plan legs are identical to the ACTIVE flight plan legs, those which are identical will not be transmitted with the SECONDARY flight plan vectors.

 

 (3)
 TEMPORARY flight plan (yellow dashed line) The temporary flight plan vectors are transmitted, if a TEMPORARY flight plan exists, for those legs which lie within the defined edit area. They are transmitted either as TEMPORARY Primary, TEMPORARY missed approach or TEMPORARY alternate according to the part of the active F-PLN to which they apply. Transmission follows the rules for the ACTIVE flight plan except rules 3 and 4 (Ref. Para. C.(1)(a)) which do not apply for TEMPORARY Primary F-PLN. If an engine-out condition has been detected, the EOSID will be transmitted as the TEMPORARY flight plan vectors until it is confirmed or cleared and the aircraft is before the diversion point.

 (4)
 Dashed flight plan (green dashed line) The dashed flight plan vectors are transmitted for the path which lies within the defined edit area under the conditions noted below.

 (a)
 If LATERAL AUTOCONTROL (NAV) is neither armed nor engaged and ARC or ROSE-NAV mode is selected, the active flight plan vectors are transmitted under the DASHED F-PLN label. The ACTIVE F-PLN label is not transmitted.

 (b)
 If LATERAL AUTOCONTROL is not armed, and PLAN mode is selected, DASHED F-PLN vectors are only sent if the secondary flight plan vectors are not being transmitted.

 (c)
 If LATERAL AUTOCONTROL is armed but the current A/C track will not intercept the active leg, operation is per rules above.

 

 


 D. Symbols
 (1) Waypoints If the flight plan contains the same waypoint in more than one position in the flight plan (primary, alternate or temporary), transmission of the symbol ident, and any associated constraint data, if appropriate (i.e. the waypoint constraint option has been selected) will occur only once.
 (a)
 Active waypoint (white) If an active leg exists in the ACTIVE flight plan, the termination of the leg is called the active waypoint symbol except in the cases noted below.

 (b)
 Flight plan waypoints (green) For the ND, flight plan waypoints are defined as the termination waypoints of all legs including the FROM waypoint (except for PPOS), but excluding the active waypoint and origin and destination waypoints. The waypoint must be within the edit area. The flight plan waypoint symbol will not be transmitted if any of the conditions described in para. (a) are true. In those cases, the display follows the rules in para. (a).

 (c)
 Pseudo waypoints (Ref. Fig. 008) The pseudo waypoints transmitted for display on the ND are subset of the performance predicted pseudo waypoints. The pseudo waypoint symbols are transmitted for the active primary flight plan and for the following mode selections:


 1_ The waypoint is an NDB and the NDB pushbutton option has been
 selected. In this case, the waypoint is transmitted as an NDB.
 2_ The waypoint is a navaid and the navaid pushbutton switch
 option has been selected, or it is a tuned navaid. In either
 case the waypoint is transmitted as a navaid or tuned navaid.
 3_ The waypoint is an airport (or an associated RWY) and the
 airport pushbutton switch option has been selected or it is
 the destination waypoint. In either case, the appropriate
 airport symbol is transmitted.
 4_ The waypoint is the termination of a FM or VM leg. In this
 case, no waypoint symbol will be transmitted.

 1 - ARC
 2 - PLAN
 3 - ROSE-NAV.
 The logic of display is given in the following pages:

 1 LEVEL 1 (magenta)

_ This is a pseudo waypoint located on the F-PLN when the following conditions are true:
 -LAT AUTO CONTROL engaged and
 -
a level segment is predicted below the FCU alt and a CLB segment is armed or active or

 -
a level segment is predicted and FINAL DES mode is engaged or

 -
a level segment is predicted above the FCU alt and a DES segment is armed or active. This pseudo waypoint is located at the level capture point.


 2 LEVEL 2 (cyan)
_ This pseudo waypoint is located at the FCU capture altitude on the F-PLN if LAT AUTO CONTROL is active. It is displayed if a climb or a descent segment is active or armed.
