The first RAF A400M took off from RAF Brize Norton on Tuesday following the investigation into the cause of the crash in Spain.
A Ministry of Defence spokesperson, said:
Having undertaken and completed a series of thorough checks on the UK’s A400M aircraft and how it is operated, we are now satisfied that the additional processes and procedures introduced means it is now safe for the RAF to resume flying. Ground and simulator training has continued during the flying pause, and crews will now be able to resume live training on the aircraft with immediate effect.
