The current four flight-test aircraft have logged a combined 684 flights totalling just over 2100 hours by 4 September.
Flight test activities being conducted from Toulouse and Seville, are "progressing steadily", and involve sorties flown with crews from the European Aviation Safety Agency (EASA). Three aircraft are routinely available and are each flown up to twice per day, while a fourth is typically undergoing work to upgrade it to the latest equipment standard.
Currently the focus is on the completion of the handling qualities, performance and systems certification tests. It's hoped to secure civil type certification from EASA before the end of this year.
The programme's fifth and final development aircraft, MSN6, is expected to join the flight-test campaign in late 2011.
Seems to be going fine....
