End-of-Mission Landing Flight Rules

  • Cloud coverage of 4/8 or less below 8,000 feet and a visibility of 5 miles or greater required.

  • The peak cross wind cannot exceed 15 knots, 12 knots at night. If the mission duration is greater than 18 days the limit is 12 knots, day and night.

  • Headwind cannot exceed 25 knots.

  • Tailwind cannot exceed 10 knots average, 15 knots peak.

  • No thunderstorm, lightning, or precipitation activity is within 30 nautical miles of the Shuttle Landing Facility.

  • Detached opaque thunderstorm anvils less than three hours old must not be within 20 nautical miles of the Shuttle Landing Facility, or within 10 nautical miles of the flight path when the orbiter is within 30 nautical miles of the runway.

  • Turbulence must be less than or equal to moderate intensity.

  • Consideration may be given for landing with a "no go" observation and a "go" forecast if at decision time analysis clearly indicates a continuing trend of improving weather conditions, and the forecast states that all weather will be met at landing time.
