Table 6 Continued [[3 column table]] | Topic | Issue | Response | | Failures | Significant damage occurs at less than rated energy | Consider downrating energy available in Flight Rules - issue in work (proposed) recent testing and/or new stator provide adequate energy | | | Reduced confidence due to large number of failures/damage | Never have failed to stop Orbiter | | Wheel Lockup | Blown tire resulting in directional control problems | Directional control still available (different braking and NWS), no cases identified which result in high speed lockup | | Tires Runway Wear | Not an issue | | | Derotation | Loads exceed single tire limits; hence, if one tire already deflated second will fail resulting in directional control problem | Nosewheel steering will maintain directional control (tire model dependent) | | Trajectory Design Exposure Time | Minimize or eliminate exposure by shaping for aborts | TAL abort capability covers a wide range of failures beyond intact abort requirement | | | | Abort shaping will reduce payload capability by several thousand pounds plus leaves no room for weight growth - recommended increasing reserve | | | | Some single payloads require TAL exposure | -B37-
