The management system plots the route to be flown in a flight plan, at least partially, by a chaining of published navigation procedures accessible from a NavDB navigation database and constituted of sequences of waypoints and/or turn points associated with specific flight constraints. It comprises a mirror memory storing the latest versions of the published navigation procedures, modified by the crew of the aircraft during the progress of the flight plan and means of substituting these latest versions stored in the mirror memory for the published versions of the navigation procedures during a change in the route predicted in the flight plan obtained by a new chaining of navigation procedures, some of which are taken from the preceding chaining. This makes it possible, during a change of navigation procedure, to take account of specific flight constraints already entered during the progress of the flight but not appearing in the published navigation procedures. |
