sequencing are not satisfied, the active primary flight plan vectors are not transmitted. In this case the secondary flight plan vectors are displayed (Ref. para. C. (2)).
3 If LATERAL AUTOCONTROL is armed and the current A/C track is
_ such that it will intercept the active leg, these vectors are transmitted and a curved path capture is drawn to the active leg (dynamically updated).
4 If LATERAL AUTOCONTROL is not armed or it is armed without
_ interception, these vectors are not transmitted in any mode. In these cases the dashed flight plan vectors are transmitted (green dashed line on the ND). (Ref. Fig. 006)
5 When an overshoot is forecast between two fixed path legs, the
_ display will be contiguous.
(b)
Alternate (cyan dashed line on ND when not active) The active alternate flight plan vectors are transmitted for those legs which lie within the defined edit area under the conditions noted below:
(c)
Missed approach (cyan continuous line on ND when not active) The missed approach vectors are transmitted for those legs which lie within the defined edit area under the conditions noted below.
1_ If ARC or ROSE-NAV mode is selected these vectors are
transmitted if the alternate flight plan is displayed on the
MCDU of the same side.
2_ If PLAN mode is selected these vectors are transmitted if an
alternate flight plan waypoint is the MRP (Ref. para. A.(3)).
1 If ARC or ROSE-NAV mode is selected, these vectors are
_ transmitted if the missed approach is displayed on the onside MCDU.
2 If PLAN mode is selected these vectors are transmitted if a
_ missed approach waypoint is the MRP (Ref. para. A.(3)).
(d) Offset path (yellow dashed line on ND when not active) The offset path vectors are transmitted for those active primary flight plan legs that lie within the defined edit area under the conditions noted below.
Flight Plan Examples
Figure 006
1_ If ARC or ROSE-NAV mode is selected and a parallel offset
exists in the flight plan, these vectors are always
transmitted.
2_ If PLAN mode is selected and a parallel offset exists in the
flight plan, these vectors are transmitted if the active
primary flight plan vectors are being transmitted.
The offset flight plan is transmitted with the active primary
flight plan vectors. The original flight plan is transmitted
in the offset path vectors.
(Ref. Fig. 007)
When an offset exists and a modification is made to the offset
(creating a temporary F-PLN), all 3 labels OFST, ACTIVE and
TMPY are transmitted to the ND following the defined rules
except in the case of a temporary "clear offset" flight plan.
In this case only the ACTIVE and TMPY labels would be
transmitted.
(e) Engine-out SID (yellow continuous line on ND when not active) The engine-out SID vectors are transmitted for those legs which lie within the defined edit area under the conditions noted below.
1 If PLAN mode is selected, these vectors are transmitted if the
_ engine out mode is not active.
2 In all modes, these vectors are transmitted:
_
-
if the aircraft is after the diversion point and the engine out mode is active, or
-
if the aircraft is before the diversion point, the engine out mode is active but the EOSID has been erased.
3 In all modes, the EOSID is transmitted as a temporary flight
_ plan (Ref. para. C. (3)) if:
-the aircraft is before the diversion point,
-
and the engine-out mode is active,
-
and the EOSID has neither been inserted nor erased.
4 Rules 1, 2, 3 apply when the aircraft is between preflight and
_ the sequencing of the last departure leg.
5 If the engine out mode is active and the EOSID has been
_ inserted before the diversion point, the EOSID is transmitted in all modes under the active F-PLN Label.

SECONDARY flight plan (white continuous line on ND when not active) The SECONDARY flight plan may consist of the Primary and Alternate flight plans, and the Missed Approach Segment. Transmission of the SECONDARY flight plan vectors includes both the Primary and Alternate flight plans and the Missed Approach legs. The flight plans are not transmitted separately as they are for the ACTIVE. Operation is the same for all modes under the conditions noted below.
