Engineer working on the nose boom of the Piper Aztec belonging to Safire, the French facility for airborne research. Measuring 1.30 m, the boom is heated so it can take measurements in freezing atmospheric conditions. The Piper Aztec is an unpressurised twin-engine piston plane. It is used for taking measurements in the lower troposphere, including measurements relating to urban pollution, air chemistry, turbulence and wind. Safire is a unit dedicated to climatic and environmental research, satellite validation and aeronautical development. It uses planes for the benefit of scientific research as part of experimental campaigns.
