Did you know ? The Aerospace Center of ISAE-SUPAERO owns the F-GSAO. It is mostly used for education and conducting flight tests. Therefore the TB-20 has been specially modified in order to host a fight-tests processing unit. A long orange anemometer perch can be seen on the right wing. This is not the only additional installation on FGSAO : on the same wing, wool yarns were installed to better visualize the stall phenomena. Inside, the processing unit gathers data from about 20 sensors installed in the aircraft (dynamic and static pressure, temperature, GPS, 3-axis accelerometer, angle of attack sensor, etc). This data is accessed using a computer (or Windows tablets), rather by saving them or accessed in real-time thanks to the software developed by the research teams of the Institute.
