The A400M (formerly known as the future large aircraft) is a military transporter designed to meet the requirements of the air forces of Belgium, France, Germany, Spain, Turkey, Luxembourg and the UK.
A European staff target was drawn up in 1993, together with a memorandum of understanding signed by the governments of the seven nations. Italy subsequently withdrew from the programme.
Airbus Military SL of Madrid, a subsidiary of Airbus Industrie, is responsible for management of the A400M programme.
Other companies with a share in the programme include BAE Systems (UK), EADS (Germany, France and Spain), Flabel (Belgium) and Tusas Aerospace Industries (Turkey). Final assembly took place in Seville, Spain.
A400M future large aircraft programme
In May 2003, a development and production contact was signed between Airbus and OCCAR, the European procurements agency, for 212 aircraft. France, Germany, Italy, Spain, the UK, Turkey, Belgium, and Luxembourg initially signed but Italy subsequently withdrew. The order was consequently reduced to 180 aircraft with deliveries starting in 2009. These will continue until 2020.
First metal cut for the airframe of A400M was in January 2005 and assembly began in 2007. The first flight was scheduled for early 2008; however, development problems with the engines caused this to be postponed. The first aircraft was officially rolled out in June 2008 and the long-awaited A400M took its maiden flight on 11 December 2009.
The aircraft took off with 127t in weight, carrying 15t of test equipment, including 2t of water ballast. Its official maximum take-off weight is 141t.

In January 2009, EADS postponed the first deliveries of the A400M until 2012, and proposed to develop a new approach for the A400M to discover new ways to advance the programme.
2009 continued to be a troubled year for the A400M as estimates on the cost overrun of the project were released with predictions of up to €11.2bn over budget. The South African Air Force started to look at alternatives to the A400M and the European partners placed it under consideration. Airbus suggested that the programme may be scrapped unless €5.3bn could be provided.
In November 2010, Belgium, the UK, France, Germany, Luxembourg, Spain and Turkey agreed to lend Airbus €1.5bn and proceed with the programme; however, Germany and the UK reduced the number of aircraft ordered to 53 and 22 respectively, decreasing the total to 170.
First deliveries were made to French Air Force in August 2013. Deliveries are expected to conclude in 2025.
A400M test flights
This first A400M is known as MSN1. The second A400M, MSN2, completed its maiden flight on 8 April 2010, while MSN3 completed its maiden flight on 9 July 2010. The fourth A400M MSN4 completed its maiden flight in December 2010. The first production aircraft of A400M (MSN7) completed its maiden flight on 6 March 2013.
The development of the A400M fleet was designated as Grizzly in July 2010. Trials with MSN1, MSN3 and MSN5 are performed in Toulouse, while those with MSN2 and MSN4 are done in Seville, providing greater flexibility and taking advantage of the best weather conditions available.
The A400M was displayed at two events in 2010: the Berlin Air Show in Germany, and the Farnborough International Airshow in the UK.
In October 2011, A400M was tested on wet runways and taxiways. The water ingestion test was completed successfully. The latest cold weather tests were concluded in February 2013.
Engine problems ground German A400Ms
Germany has grounded two of the three Airbus Defence and Space (DS) A400M transport aircraft that it has so far received following the discovery of excessive engine wear, national media disclosed on 30 June.
Flight operations of aircraft 54-01 and 54-02 – the first two received in December 2014 and December 2015 – have been temporarily suspended after inspections found heavy engine wear after only 365 and 189 hours of operations respectively, Der Spiegel reported, adding that engine wear on the third aircraft, 54-03, had also been identified.
This issue is likely to be connected to problems that were identified with the EuroProp International (EPI) TP400-D6 engine earlier this year. In April it was reported that engines were being affected by excessive abrasive wear and heat resistance. It was noted that parts of the engine were struggling to stand up to the extreme temperatures, with individual components found to be flawed. A UK Royal Air Force aircraft suffered an in-flight engine shutdown as an apparent result of these issues.
At that time Airbus DS said that it was working hard to solve the issue of excessive abrasive wear, noting that it “has no impact on the security of the plane”.
It is understood that the issue has been isolated to the propeller gear-box (PGB); the part that converts the rotating high-speed motion of the engine into a slower speed motion for the propeller. A significant number of engines that are both on the final assembly line (FAL) and in service have had to be replaced because of quality issues, though the issue affects only gearboxes with a clockwise rotation.
EPI has performed an analysis of the issue, identified the root cause, and developed a procedure whereby each gearbox is inspected every 200 hours. If a crack is found the gearbox is then inspected every 20 hours after that to keep the aircraft that have been delivered flying.

Total firm orders for the A400M stand at 174 aircraft. Malaysia ordered four and 170 aircraft were ordered by seven countries, including the UK (22), Belgium (7), Turkey (10), France (50), Germany (53), Luxembourg (1) and Spain (27).
Looming capability gap in Germany’s military transport fleet may result in the MoD to urge A400M partner nations to procure & jointly operate C-130 Hercules: Here
A looming capability gap in Germany’s military transport fleet may result in the Ministry of Defense looking to urge A400M partner nations to procure and jointly operate a limited fleet of C-130 Hercules airplanes. Ongoing participation of German forces in Mali has highlighted the need for aircraft capable of landing on small and poorly fortified airfields and participation in special operations, limitations found in the A400M. At present, Germany operates the C-160 Transall which is due for retirement in 2021.

In April 2005, South Africa signed a contract with Airbus Military to be a full participant in the A400M programme. South Africa ordered eight aircraft, for delivery between 2010 and 2014. South Africa then cancelled the order in November 2009. In December 2005, Malaysia signed a contract for the purchase of four A400M.

America is key to export sales of the A400M Atlas, as Airbus Defence and Space prepares to pitch the airlifter to the biggest Western military market amid recent technical troubles.
“The US will be our target, but clearly not today,” Fernando Alonso, head of the company’s military aircraft division, told journalists June 20. The European company is still focusing on fixing cracks on its propeller gearbox and cracks on the central part of the fuselage on some aircraft.

At the moment engines, or more specifically the GE Avio-produced power gearbox, are the major cause for concern – limiting flying hours between inspections and disrupting delivery flow.
Airbus could ask for bail-out due to A400M military plane: Here
Airbus could ask for a bail-out from Britain and other countries buying its A400M military transport aircraft after take a massive hit on the project.
The pan-European aerospace company’s annual results showed Airbus took a €2.2bn charge because of problems with the A400M, with chief executive Tom Enders calling renegotiations of the contract.
And here’s a cool video filmed by Ben Ramsey who got a great close-up footage!
The A400M has a much larger payload than the C-160 Transall and C-130 and the design makes extensive use of composite materials. The capability for short, soft field landing and take-off is part of the requirement and the aircraft has six-wheel high-flotation main landing gear.
The need for airdrops and tactical flight requires good low-airspeed flight and the aircraft also has long-range and high-cruise speed for rapid and flexible deployment.

The EADS Defence Electronics defensive aids suite includes an ALR-400 radar warner from Indra and EADS, MIRAS (multicolour infraRed alerting sensor) missile launch and approach warner developed by EADS and Thales, and chaff and flare decoy dispensers. A laser DIRCM (directed infrared countermeasure) system may be added later.
ALR-400 radar warner
The ALR-400 is an advanced radar warning system developed specifically for the Airbus A400M tactical military transport aircraft. ALR-400 would be able to effectively detect any incoming radar-based threat. The system is being produced by a team comprising EADS Defense Electronics and Indra of Spain.
ALR-400 radar warner, defensive aids computer, MIRAS multi-color missile warner and a chaff/flare dispenser are the basis for the A400M aircraft self-protection system which is expected to achieve initial operational capability by 2010 with 85 systems on order to equip the same number of A400Ms. Source deagel.com
The aircraft can also accommodate armour plating crew protection, bulletproof windscreens, engine exhaust treatment for infrared emission reduction and inert gas explosion retardation and fire retardation in the fuel systems. The wings have hardpoints for the installation of electronic warfare pods and refuelling pods.
A400M transporter cargo systems
Rheinmetall Defence Electronics is supplying the loadmaster control system for electronic cargo control. Loadmaster consists of a workstation and control panel, eight sidewall lock panels and a crew door panel. It provides efficient ground loading and airborne cargo drops.
Loadmaster Workstation (LMWS)
The loadmaster uses the Loadmaster Workstation (LMWS) to finalize the load and trim sheet required for takeoff, which was prepared with the MPRS and transmits it electronically via an aircraft server to the cockpit, where it is printed and signed. This is one of the few remaining paper formats still existing in the A400M system.
New ground is broken when it comes to the responsibilities of the loadmaster: The A400M loadmasters are to accomplish not only logistical, but also technical tasks on the aircraft in future.
Particularly the technical part presents new challenges in the fields of personnel selection and training. In simple terms, the technical qualification of the loadmasters will conform with the EASA CAT A level; thus, jobs up to maintenance level 1 (onboard) can be carried out.
This approach requires a completely new training cycle: Depending on the previously acquired technical skills, e.g. the Air Forces Engineering schools will provide an “EASA CAT A equivalent delta training course.” Subsequently, the A400M loadmaster type rating course will take place – the traditional loadmaster training course on the A400M aircraft as well as the “Maintenance Course for Loadmasters.”
Building upon the CAT A knowledge, the latter will convey A400M-specific contents. Thus, the loadmaster will become capable of conducting “ground handling and servicing”, simple troubleshooting and maintenance activities.

The cargo bay can transport up to nine standard military pallets (2.23m × 2.74m), including two on the ramp, as well as 58 troops seated along the sides or up to 120 fully equipped troops seated in four rows. For Medevac, it can carry up to 66 stretchers and 25 medical personnel.
Right dropping door and wind deflectors used during the jump
The A400M can carry 116 paratroops and air-drop them and their equipment either by parachute or gravity extraction. It can air-drop single loads up to 16t; multiple loads up to 25t total; 120 paratroops plus a wedge load of 6t, or up to 20 1t containers or pallets.
It can also perform simultaneous drops of paratroops and cargo (RAS / wedge or door loads) and very-low-level extraction (VLLE) of a single load up to 6.35t, or multiple loads up to 19t total weight. Gravity extraction can be performed for a single load up to 4t, or multiple loads up to 20t total weight.
The cargo compartment can be configured for cargo, vehicle or troop transport or air drop, a combination of these and for aero-medical evacuation. A single loadmaster is able to reconfigure the cargo compartment for different roles either in flight or on the ground. A powered crane installed in the ceiling area of the rear section of the fuselage has a 5t capacity for loading from the ground and for cross-loading.
The rear-opening door has full compartment cross-section to allow axial load movement, roll-on and roll-off loading and for the air drop of large loads.
A400M tactical tanker and refuelling
The A400M is convertible to a tactical tanker, with the ability to refuel a range of aircraft and helicopters within two hours. Flight Refuelling Ltd is supplying the 908E wing pod drogue system, which provides a fuel flow of up to 1,200kg/min for each pod, plus the centreline pallet-mounted hose drum unit fitted in the rear cargo bay, which provides a fuel flow of 1,800kg/min.

The A400M can now refuel fighters and transports from underwing pods, but helicopter stability in trail has proved problematic. A longer hose may be the solution. – ainonline.com
In addition, up to two cargo bay fuel tanks (CBT), which connect directly to the A400M’s fuel management system, can be fitted. Total fuel capacity is 46.7t or 58t with the CBTs.
Airbus A400M Atlas Airborne Refuelling Chart
In October 2011, GKN Aerospace won the £6m ($9.54) contract from Cobham Mission Equipment. It includes supplying air refuelling pylon for A400M. It also supplies a wing spar for the A400M.
The aircraft’s independent navigation system comprises an inertial reference system (IRS) integrated with a global positioning system (GPS). The weather and navigation radar is the Northrop Grumman AN/APN-241E, which incorporates wind shear measurement and ground mapping capability.
Northrop Grumman AN/APN-241E
The only radar in the transport class with a high resolution SAR mapping mode
The AN/APN-241’s capability remains unmatched by the competition as the only radar in the transport class with a high resolution SAR mapping mode. In addition to meeting needs for precision navigation, this unparalleled mapping capability enables operators to execute landing missions with confidence on unimproved runways without aid from ground-based landing systems.
No other radar in the industry can compete with the range and accuracy of the AN/APN-241. It is the only radar with a 10nm range Windshear mode and its unique two-bar can technology eliminates false alarms. And, unlike other systems, the AN/APN-241 windshear mode is not restricted by altitude. At 20 nautical miles, the AN/APN-241 provides the longest range air-to-air situational awareness mode of any transport radar. The Skin Paint mode also features computer generated target-sizing, a clutter-free display, and hands-free operation to the crew.
The AN/APN-241 is designed to allow pilots to focus on the mission rather than “working” the radar. Automatic tilt and gain adjustments reduce operator tasking, and with simultaneous mode interleaving, crews can select independent radar modes according to mission requirements. The AN/APN-241 provides overlays of flight plan or TCAS information on weather or ground maps for greater situational awareness. Operators may also ‘freeze’ the AN/APN-241 into a non-emitting mode to gain a tactical advantage.
The AN/APN-241 was built with growth in mind. Modifications to current modes and technologies will provide a maritime patrol capability suitable for fisheries protection, smuggling interdiction, and Search and Rescue missions. With the development of ‘Ballistic Wind’ mode, a modification which will measure drop zone winds, the AN/APN-241 provides a unique air drop capability to support both military and humanitarian missions.
The highly adaptable AN/APN-241 is currently fielded on four aircraft: C-130H, C-130J, C-27J and C-295. Northrop Grumman has integrated the AN/APN-241 with five different avionics architectures and two antenna systems. As the baseline radar for the LMCO C-130J and Alenia C-27J, it has a solid, long-term production base with logistics and maintenance support through 2030 and beyond.

Engines onboard the A400M
In May 2003, Airbus Military selected the three-shaft TP400-D6 turboprop engine, to be manufactured by EuroProp International (EPI). EPI is a consortium formed by Rolls-Royce (UK, Germany), ITP (Spain), MTU (Germany) and Snecma (France). Rolls-Royce is responsible for overall integration.
EuroProp International (EPI) TP400-D6 engine
The development of this advanced military turboprop engine is shared by ITP, MTU Aero Engines, Rolls-Royce and Snecma. The partners have launched a joint company, Europrop International (EPI), to develop, manufacture and support the TP400-D6.
The TP400-D6 powers the A400M military transport which has successfully completed its maiden flight in Spain’s Seville in late 2009. The TP400-D6 successfully entered into service with the French Air Force in late 2013.
MTU is responsible for the TP400-D6’s intermediate-pressure compressor, intermediate-pressure turbine and intermediate-pressure shaft and has a stake in the engine control unit. Furthermore, final assembly of all TP400-D6 production engines takes place at MTU Aero Engines in Munich and acceptance testing at MTU Maintenance Berlin-Brandenburg. Source mtu.de

Messier-Dowty was chosen as the supplier of both main and nose landing gear. Each main landing gear consists of three independent twin-wheel assemblies, providing six wheels on each side. This allows the plane to land on unprepared runways. The landing gear system also enables the A400M to ‘kneel’ which lowers the rear ramp to facilitate the loading of large vehicles.
The main landing gear shock absorbers maintain a minimum distance from the ground whatever the load. Messier-Bugatti supplies wheels and brakes. The aircraft has two nose wheels and 12 braked wheels.
EuroProp International (EPI) has developed TP400 power plant for the A400M. The power plant has been installed on the inner engine mount of the C-130K flight test-bed.
The A400M’s normal operating speed is 555km/h, but it can reach a maximum speed of 780km/h. The normal and ferry ranges of the aircraft are 3,298km and 8,710km respectively. The service ceiling is 11,300m.
The take-off and landing distances of the aircraft are 980m and 770m respectively. The aircraft weighs around 76,500kg and the maximum take-off weight is 141,000kg.
