This thesis deals with the development of software applications and hardware devices to enable the automatic analysis of flight test data from a fixed-wing aircraft and to provide real-time feedback to the flight crew regarding the outcome of each test point performed. The ultimate mission of this work is to make flight activities more efficient and safer, allowing immediate detection of unsafe flight conditions and instantaneous verification of the pass/fail criteria for each of the performed tests. This is especially relevant for flutter flight testing, given the risks associated with this type of tests, but it's also applicable to other kinds of flight tests, such as climb/glide performance analyses or level flight performance testing.
