The test was performed on 19 July with aircraft MSN1.
While the twin-engined A350 has already conducted rejected take-
off tests, the maximum-energy event is intended to examine the
extreme case of a rejection athigh speed and high weight
with braking capability at its limits.

Airbus says the brakes reach a temperature of around 1,400C as
a result of the energy absorbed in stopping the aircraft.

Under the certification criteria the aircraft must remain standing for

Airbus says the test was "successfully performed". The maximum-
energy test is left until last because of the risk of damage to the
aircraft.

Certification will follow a series of route-proving flights which will
begin in July. The A350 test fleet has accumulated over 540 flights
and clocked up 2,250h.
