Pipistrel Virus SW, Rotax 912iS 100hp, test flights resumed last week after 25 hrs TTIS. Just beyond Moorabbin training area, near Phillip Island Victoria, Australia. Engine performance, avionics and airframe appear excellent, and in the air the aircraft has checked out AOK these past few days. However, the fuel system components, including pipes, attachments and connectors, will be explored further to ensure they are nominal and that there is no slow occult leakage. Stay tuned.
