The Airbus Military A400M new generation airlifter has passed a series of key tests in the last week as the aircraft continues to progress towards civil and military type certification. On 17th September the aircraft (Grizzly 1) successfully performed the high-energy rejected take-off test which confirms the capability of the braking system to stop the aircraft safely following a rejected take-off at high speed and high weight. During the week the emergency evacuation tests were also carried out to demonstrate that the aircraft can be safely evacuated in a specified time when loaded with troops or other passengers in various configurations.
The high-energy rejected take-off test is one of the toughest in the programme and, because of the risk of damage to the aircraft, is among the last items performed before preparation of the aircraft flight manual. It was carried out on runway 14R at Toulouse Airport and required the aircraft, loaded to the maximum take-off weight, to make a simulated take-off run which was aborted at the V1 decision speed. V1 is the maximum speed at which the pilot has to decide whether to continue a take-off or abort it.
