Flight tests of new or modified aircraft are a necessary part of the design process and provide the final validation of the full scale aircraft design. Flight testing for certification is a critical phase as all trials proving compliance with specifications and regulations must be completed in the shortest possible time, while maintaining high quality standards in the certification process. Usually a heavy instrumentation is installed to validate the predicted behaviour of the aircraft and also to detect unforeseen problems so that, if necessary, fast modifications can be done.

Optical measurement techniques can minimize the installation effort and reduce the testing time as they are able to capture a huge amount of parameters within a short time. The preceding project AIM Advanced In-flight Measurement Techniques proved the principal feasibility to apply modern optical measurement techniques as being used in industrial wind tunnels to flight testing.
