Flight envelope protection is included in the A400M's FBW software, so it therefore has the benefit of allowing 'carefree' manoeuvring up to the extremes of the envelope without the risk of structural damage.
The A400M is very agile for its class - as anyone attending Farnborough or RIAT will be able to witness. 2.5G has always been the manoeuvre value assumed in the A400M technical review brochure, with a structural ability to cope with sustained 3.0G turns at lower weight.
