Frequently asked questions
What runways are available at KSUS?
Spirit of St Louis Airport operates two paved runways. Runway 08R/26L is the longer of the two at 7,486 feet, with a width of 150 feet and a concrete surface. Runway 08L/26R measures 5,000 feet long and 75 feet wide, surfaced in asphalt. The longer runway carries a PCR value of 310/R / C/W / T, while the shorter one is rated 100/F / D/X / T. Note that 08R/26L is closed to touch-and-go landings.
Are there weight restrictions for aircraft operating at Spirit of St Louis Airport?
Yes, Spirit of St Louis Airport is closed to aircraft over 100,000 pounds. Aircraft weighing between 100,000 and 150,000 pounds may operate only with prior permission, requested from the airport manager. There is no accommodation described for aircraft above 150,000 pounds. Operators planning heavier movements should factor this weight ceiling into aircraft selection for this field. The restriction applies airport-wide rather than to a single runway.
Is Runway 08L/26R usable for scheduled passenger operations at KSUS?
Runway 08L/26R at KSUS carries restrictions for certain commercial passenger flights. It is not available to Part 121 or Part 380 scheduled passenger operations carrying more than 9 passenger seats, nor to non-scheduled passenger operations exceeding 30 passenger seats. The parallel taxiway and connecting taxiways serving this runway are also closed to Part 121 air carrier operations. Operators flying under these categories with larger passenger loads should plan to use the other runway, 08R/26L, instead.
What noise abatement procedures apply at Spirit of St Louis Airport?
Spirit of St Louis Airport has noise-sensitive areas to the south of the field and enforces two separate noise abatement procedures tied to aircraft stage classification. Departing Stage III aircraft are directed to use Runway 08L/26R between 2300 and 0600. Departing Stage II aircraft are also directed to Runway 08L/26R, but under a wider window of 2200 to 0700, except with prior permission required Monday through Friday between 0800 and 1700 and at other times. Pilots and dispatchers should account for these runway assignments when planning night departures at KSUS.
How does military aircraft access work at KSUS?
Military aircraft operating at Spirit of St Louis Airport require prior permission requested 24 hours in advance, arranged by contacting airport operations directly. This applies to all military aircraft without exception noted in the airport's remarks. Operators supporting military movements into KSUS should build this advance coordination step into their planning rather than treating the field as open access. The requirement stands separately from the airport's general weight and runway restrictions.
