Method for facilitating the approach to a platform present on a liquid surface with an aircraft comprising: - a preparation phase for preparing an approach trajectory to a theoretical position of said platform, characterised in that said method comprises: - a safety phase of making said approach trajectory safe, during which: ∘ over time the current position as well as the direction of travel and the speed of travel of the floating and flying objects provided with an automatic identification system which are present in a predetermined monitoring zone are determined, ∘ a danger level of each object relative to said approach trajectory followed by the aircraft is determined, ∘ a horizontal representation of said approach trajectory is displayed on a display screen, as well as for each object: a plot representing the current position of the object, an indication of the direction of travel of the object and a representation relating to the danger level of the object, ∘ an approach corridor of a given width centred on said approach trajectory is displayed on said display screen, and in that during the safety phase, the approach trajectory passing through a final approach point, before this final approach point is reached by the aircraft: - the time (TFAF) needed for said aircraft to reach this final approach point is determined, - the predictive position which each of said objects will have when said aircraft reaches the final approach point is determined, - the danger level of each object as a function of its predictive position and of its current position relative to the approach corridor is determined. - a preparation phase for preparing an approach trajectory to a theoretical position of said platform, - a safety phase of making said approach trajectory safe, during which: ∘ over time the current position as well as the direction of travel and the speed of travel of the floating and flying objects provided with an automatic identification system which are present in a predetermined monitoring zone are determined, ∘ a danger level of each object relative to said approach trajectory followed by the aircraft is determined, ∘ a horizontal representation of said approach trajectory is displayed on a display screen, as well as for each object: a plot representing the current position of the object, an indication of the direction of travel of the object and a representation relating to the danger level of the object, ∘ an approach corridor of a given width centred on said approach trajectory is displayed on said display screen, ∘ over time the current position as well as the direction of travel and the speed of travel of the floating and flying objects provided with an automatic identification system which are present in a predetermined monitoring zone are determined, ∘ a danger level of each object relative to said approach trajectory followed by the aircraft is determined, ∘ a horizontal representation of said approach trajectory is displayed on a display screen, as well as for each object: a plot representing the current position of the object, an indication of the direction of travel of the object and a representation relating to the danger level of the object, ∘ an approach corridor of a given width centred on said approach trajectory is displayed on said display screen, - the time (TFAF) needed for said aircraft to reach this final approach point is determined, - the predictive position which each of said objects will have when said aircraft reaches the final approach point is determined, - the danger level of each object as a function of its predictive position and of its current position relative to the approach corridor is determined.
