Vilas, out of curiosity, the airbus logic regarding overflying of destination seems to have changed somewhat, either that or my memory is playing tricks! There used to be a reference in my OMB, indeed stating that overflying the runway would sequence the destination and erase the flight plan. That reference is there no longer.
Airbus now states more or less the following (full reference:22_20-30-10), depending on FMGC model, either:
-sequencing is inhibited unless XTK <.5 NM and <30 degree track difference between aircraft and leg
-waypoint is sequenced when <7 NM and track <90 degrees
Both suggest that Airbus have addressed the issue since merely overflying the destination will now not normally erase the flight plan. Please correct my if I'm wrong, I'm still tryingto work it out.
