Can Airbus A400M take-off from the beach fully loaded?
The surface of the beach will need a certain California Bearing Ratio to be allowed to have the aircraft land there. This will be measured by the ground support prior to the arrival of the aircraft.
This will allows the aircraft to operate largely normally when on the ground roll and taxiing, however the crew would need to be mindful about brownout when using reverse thrust and to be gentle when turning so as not to bury the nose wheel.
The aircraft will have a maximum mass for operations at the given CBR. There will also be a max mass based on the aircraft performance versus the field conditions and parameters with margins for safety (though not the same as standard Engine-Out performance or Balanced Field) which is unlikely to be its normal maximum takeoff mass.
EDITED for scope.
