The first aircraft was delivered to the French Air Force in August 2013. In March 2013, the A400M received European Aviation Safety Agency (EASA) certification. A total of 174 A400M aircraft had been ordered by eight nations by July 2011. Between 20, the A400M faced cancellation as a result of development programme delays and cost overruns however, the customer nations chose to maintain their support for the project. The A400M's maiden flight, originally planned for 2008, took place on 11 December 2009 from Seville Airport, Spain. In addition to its transport capabilities, the A400M can perform aerial refueling and medical evacuation when fitted with appropriate equipment.

The A400M is sized between the C-130 and the Boeing C-17 Globemaster III it can carry heavier loads than the C-130 and can use rough landing strips. It was designed by Airbus Military (now Airbus Defence and Space) as a tactical airlifter with strategic capabilities to replace older transport aircraft, such as the Transall C-160 and the Lockheed C-130 Hercules. The Airbus A400M Atlas is a European four-engine turboprop military transport aircraft. Further investigations with positive and negative pitching revealed a second hysteresis loop in the deep post stall region resulting in a difference of 0.2 in moment coefficient and 0.5 in lift.Airbus Military / Airbus Defence and Space The pressure was used to gain lift, pressure drag, moment data. The experiments were conducted in terms of surface pressure distribution over the airfoil for a tripped and a baseline configuration. The typical problem of blockage within a wind tunnel was avoided using an open test section. The present paper analyzes and discusses the performance of the symmetrical NACA 0021 airfoil at three Reynolds numbers (Re = 100k, 140k, and 180k) through 180 deg incidence. The post stall data of airfoils is crucial to improve the prediction of the start-up behavior as well as the performance at low tip speed ratios. While literature often covers incidence ranges smaller machines experience a range of up to 90 deg for horizontal axis and up to 360 deg for vertical axis wind turbines (VAWTs). Wind turbine industry has a special need for accurate post stall airfoil data.
