In the run-up for its planned first flight early next month, the A400M prototype has been handed by Airbus Military to the flight-test organization to initiate the required ground trials.

The milestone sets off a series of test events to ensure flight instruments are working correctly, the TP400 turboprops are ready, and the engine/aircraft interface poses no concerns. The next few weeks will see engine run-ups, then taxi tests, beginning with low-speed tests reaching a maximum 60 knots, and rejected takeoff brake tests at 120 knots.

Airbus Military notes each of the tests will be followed by close analysis from flight-test engineers before the ground test program advances.

During this phase, telemetry equipment to be used during flight-tests also will undergo final checks.

The A400M program is running about three years behind schedule. The full authority digital engine control software, which was among the pacing items in recent months for flight, is now delivered.

Meanwhile, industry officials remain in talks with government customers about changes to the fixed-price development contract.

Those talks also are supposed to come to a conclusion by around year's end, although the pace of discussions has slowed and a new contract is now not expected until at least next year.
