Yes, that is SOP on the A380. The A380 is only equipped with TR on the inboard powerplants. The most significant reason is that on standard width runways, the outboard powerplants are over or near the edges, and deploying TR over grass would throw dirt, grass and what not into the air, causing a FOD nightmare. Secondly, the A380 is certified to stop without using any TR, as she has very large brakes. TR aids slowing on short runways, poor braking action situations (wet/snow/ice), or when an early turnoff is needed. Hope this helped!
