Engines - Reverse Thrust

``` Use for ground operation only. # Intentional selection of reverse thrust in flight is prohibited. # Backing the airplane with the use of reverse thrust is prohibited. ``` RR-Trent 892 (AFM Limit) After a rejected take-off (RTO) is performed, where thrust reversers were deployed, take-off is prohibited until maintenance action is complete.
