Table 1 ROutine KSC Landing Concerns - Issue Overview [[3 column table]] Topic | Issue | Response Weather Availability | KSC lighted opportunities not as frequent as EAFB. Time spent waving off KSC is wasted turnaround time | Certain periods (mornings after sunrise) good at KSC, night weather also good | | EAFB opportunities occur after KSC so waveoff available; however, EFB has wet lakebed runway availability problems in winter and wind forecast problems in spring/summer afternoons Forecast Ability | KSC weather more difficult to forecast 90 minutes ahead | Tropical weather and night/day transition is difficult; other conditions can be forecast (midmorning, fall through spring days). | | Conservative rules and forecasts result in no go for marginal weather | Insufficient tools available to make forecast | Tool upgrade to current state of art - MIDDS - forecasts are more conservative than necessary Nosewheel Steering | Does not provide redundant control. Numerous single point failures. Nosewheel steering is mandatory to stay on the runway for the case of double tire failures. | Program in work (not funded) to upgrade to fail OPS/fail safe (proposed). The system is designed to be used to protect for high speed tire failures | | Current system is fail passive KSC Runway Roughness | Causes high tire wear - increased risk of blowout | Placard crosswinds (proposed for RTLS) -B7-
