Wow, I did not expect this thread to grow that much. Thank you for all your comments!
The exact subject of my thesis is not specified yet. Perhaps I could ask you to help me with finding something interesting thanks to which I could gain some practical flight testing knowledge?
I have a free access to several types of flight simulators (some of them are military ones) and a support of experienced ex TP (not in the business for at least 15 years). In theory, I could also conduct some real flights (altough, due to the risky nature of flight testing, it would be hard to convince to that my school's authorities - even with previously mentioned TP onboard).
My initial idea was to choose let's say 2 most advanced flight simulators, treat them as real aircrafts, test them using flight testing procedures, collect the data and compare the results with real characteristics of actual aircrafts. What do you think?
