NOTE : (1) indicates that pilot may enter or modify this
____ pseudo waypoint directly on the F-PLN page of the MCDU.
 (b) Stringing rules The flight plan may be divided into three segments. The data elements designated within each segment are as follows :
 -Departure : Initial fix, which is the origin airport or a runway at that airport. RWY transition (If an EOSID is defined, it is automatically selected). SID SID Enroute transition.
 -Enroute : Initial fix (if there is no departure segment). Airway Direct
 -Arrival : STAR Enroute transition STAR (STAR common route + STAR RWY transition) Approach transition Approach Missed approach.
 The segments, if they exist, are strung in this order. The stringing of 2 elements is automatically performed provided that a common waypoint to both elements exists. If not there is a discontinuity.
 If a departure (or arrival) element does not exist, the previous element and the next one are strung.
 NOTE : The destination airport of a flight plan may designate an
____ alternate destination. The associated alternate flight plan has the same structure as the primary ACTIVE flight plan.
 The segments and elements of individual segments are strung as defined below : (in the order the segments appear in the F-PLN).

Departure procedure (Ref. Fig. 006) The only possible revised point for a departure procedure selection is the origin waypoint (of primary or alternate F-PLN). The various elements of a departure procedure are first strung together in this order: RWY Transition, SID, SID-Enroute Transition. A matching point for the terminating waypoint of each element is searched downstream in the following existing element. The 2 elements are strung together at this point, ignoring any part of the 2nd element occurring before the identical waypoint. Once the Departure procedure is constructed a matching waypoint for the last fixed waypoint of the procedure is searched downstream in the flight plan down to the destination waypoint. The procedure is strung in the flight plan at this point, ignoring any part of the flight plan occurring before the identical waypoint. If no matching waypoint is found, the procedure and the flight plan are strung with a discontinuity. In the case any of the following lateral revisions is performed at a waypoint of the selected Departure Procedure, the revised waypoint becomes the last waypoint of the Departure Procedure:
