(c) 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. (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 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. (Ref. Fig. 006) 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:
1_ Departure segment
- A matching point for the terminating waypoint of each
element is searched downstream in the following existing
element. At this point the two elements are strung together,
ignoring any part of the second element occurring before the
identical waypoint.
- If a runway is selected without SID and/or TRANS, the
departure is defined by the runway and a FA leg starting at
runway fix on the runway axis up to 1500 ft. AGL followed by
a Flight plan discontinuity.

Departure segment - Enroute segment A matching waypoint for the last fixed waypoint of the procedure is then 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. (Ref. Fig. 007)
