| The versions, their flights pooled together making up 400, include the technology demonstrators 1 and 2 (TD 1&2), and the prototype versions 1 and 2 (PV 1&2). On Saturday morning, the TD 1 and the PV 1 were test flown for 47 minutes, the agency said. |
| The flight tests were conducted for calibration of an air data system at different altitudes and speeds for TD 1, which was "ready for exploration of the flight envelope further". |
| The aircraft has been fitted with a new nose air data probe during a scheduled servicing, after 75 hours of flight, the agency said. |
| PV 2, with lighter structures, new avionics and cockpit displays, was being tested for vibration and "structural coupling". It would soon be fitted with a multi-mode radar and R73 missile and drop tanks. |
| The agency said it would aim to fly the PV 2, for the first time, next month. |
