_________________________________________________
 1. General
_______ The Flight Management System may contain two different flight plans. The first, called active flight plan, is used as a basis for primary display on the MCDU and the ND, for deviation signal evaluations, radio navigation autotuning, performance predictions, fuel planning and lateral and vertical guidance when coupled to the autopilot. The other is the secondary flight plan. It is used for display only. It can be used to prepare a second departure procedure before takeoff, for routing comparison, to prepare the next flight leg (laterally and performance wise). Each flight plan is composed of the same elements (Ref. para. 2A):
