The A380 was initially planned without
thrust reversers, incorporating sufficient braking capacity to do without them.
[127] However Airbus elected to equip the two inboard engines with thrust reversers in a late stage of development helping the brakes when the runway is slippery. The two outboard engines do not have reversers, reducing the amount of debris stirred up during landing. The A380 has electrically actuated thrust reversers, giving them better reliability than their pneumatic or hydraulic equivalents, in addition to saving weight.
