The survey helicopter, AS350, owned by Icarus Elicotteri, was employed for an airborne geophysical survey over Mt. Vesuvio by the Geological Survey of Austria (GBA)

They used a heliport in Santa-Agata, Sorrento, Italy, as an air base for the survey on the other side of Naples Bay. White cases in the front of the helicopter are a magnetic bird and two VLF birds from the left in the order. They suspended those birds by cables from the helicopter for the survey. NaI crystals were also installed on the helicopter for a gamma-ray survey. The heliport is located on a terrace with higher altitude and heavy fogs and low temperatures annoyed them, but a fine weather promoted the survey. They had a bad reception of GPS signals west of Mt. Vesuvio and had to use video images to locate flight paths (Supper et al., 2001).
