Method and device for constructing a low altitude flight trajectory intended to be followed by an aircraft. The device (1) comprises, in particular, a means (6) for constructing a lateral trajectory of the flight trajectory and a means (7) for constructing a vertical trajectory of the flight trajectory, over a profile section defined between two height maxima of a terrain profile, by displacing over the terrain profile a V-shaped construction profile, whose branches are determined respectively by maximum angles of climb and of descent and by selecting a position of the construction profile, for which its edges arrive tangential to the terrain profile, and no peak of the terrain profile crosses the construction profile, the position thus selected of the construction profile allowing the latter to form the part of the vertical trajectory which is situated at the level of said profile section.
