Following the success of the three editions of IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace), it was considered convenient to promote a fourth edition of this event, which aims at reinforcing and supporting the collaborations among people working in developing instrumentation and measurement methods for aerospace. This new edition will keep pursuing the state of the art and practice started over the past years. Attention is paid, but not limited to, new technology for metrology-assisted production in aerospace industry, aircraft component measurement, sensors and associated signal conditioning for aerospace, and calibration methods for electronic test and measurement for aerospace. The program is designed to raise the interest of a wide group of researchers, operators and decision-makers from metrology and aerospace fields, by presenting the most innovative solutions in this field from the scientific and technological point of view.
