The Airbus A380, the world's largest passenger plane, might seem to require extensive measures to come to a stop after landing. One might assume that this would include reverse thrusters on all four of its engines. However, this is not the case.
Reverse thrusters are just one component of the A380’s braking system. During the design phase of the A380, it was determined that equipping all four engines with reverse thrusters introduced more problems than benefits.
