This paper shows some important results from a test campaign conducted on the Dardo Aspect, a wet-laminate full-composite very-light airplane (VLA). Both static and dynamic experimental analyses are carried out. All the results and methodologies utilized in this paper take into account compliance with certification requirements. Particular attention is dedicated to demonstrating the reliability of some innovative techniques, such as the Digital Image Correlation (DIC), the operational modal analysis (OMA) and the taxing vibration test (TVT), which cannot yet be used for certification purposes. As a matter of fact, these techniques allow for a significant reduction in time and costs although may present some problems related to calibration and testing preparation.
