The invention relates to a portable helicopter landing area and to the use method thereof. The inventive device comprises two cases (1, 2) which can be carried by the person on the ground (X) and which are intended to be disposed on the selected surface or area (H). Moreover, two units (A, B) can be removed from the aforementioned two cases respectively. The visual positioning unit (A) comprises: a light which produces four successive white flashes (7) and which is visible from a distance of at least forty kilometers by an aircraft pilot, and a high-frequency current generator unit. The lighting unit (B) comprises: (i) at least five marker lights (16a to 16e) which are disposed in the form of a Y on the ground, thereby creating five white points on the ground which turn blue when the pilot reaches the vertical above the selected landing area or surface (H); and (ii) a kit for the assembly of an illuminated wind cone which provides information relating to the wind at the aforementioned selected landing area or surface (H). The invention is suitable for emergency operations requiring the intervention of at least one airborne team and, in particular, a heliborne team.
