Abstract: The present invention relates to a method of assisting in the checking of at least one flight plan among at least a first flight plan and a second flight plan, each flight plan being associated with an ordered list of elements. The method comprises the steps of comparing flight plans in order to identify among the elements associated with said plans, common elements for all the plans and distinctive elements for each flight plan, and to display, a first comparative zone comprising a tree structure defining a plurality of levels, each level comprising a single root formed from one of the common elements or a branch for each flight plan, at least one of the branches in a same level comprising at least one of the distinctive elements associated with the corresponding flight plan.

Abstract: The method comprises a step of simultaneous scanning the list of elements of each flight plan comprising for each given pair of a first scan index and a second scan index, a comparison between the first flight plan element whose position index corresponds to the first scan index and the second flight plan element whose position index corresponds to the second scan index, according to the following sub-steps when the first element is identical to the second element, adding at least one of said elements in a resulting list with a “no difference” marker; otherwise, adding in the resulting list, the first element with a marker “removed” and the second element with a marker “added”.
