KS64 · Stanford Airport/Biggerstaff Field
Stanford Airport/Biggerstaff Field serves Stanford, Montana at 4,327 ft elevation with its longest runway, 11/29, at 4,200 by 75 ft. The figures below are computed from FAA NASR runway data (via OurAirports) and the same rules of thumb JetDesk uses on the airport page in the app; the POH and current NOTAMs are the authority.

01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 11/29 | 4,200 × 75 ft | asphalt | lit |
| 07/25 | 2,260 × 100 ft | asphalt | unlit |
02Density altitude and turboprop runway margins
Standard temperature at 4,327 ft is about 6°C. Every 1,000 ft of density altitude adds roughly 8 percent to a turboprop's takeoff distance and 5 percent to its landing distance. The table uses Piper Meridian book numbers (2,438 ft takeoff and 2,110 ft landing over a 50 ft obstacle at sea level, ISA, max weight) as a reference airplane; heavier turboprops and light jets scale the same way from their own POH figures.
| Conditions | Density altitude | Takeoff est. | Landing est. | Landing × 1.5 |
|---|---|---|---|---|
| Standard day (ISA, 6°C) | 4,327 ft | 3,282 ft | 2,566 ft | 3,850 ft |
| Warm day (ISA +10) | 5,527 ft | 3,516 ft | 2,693 ft | 4,040 ft |
| Hot day (ISA +20) | 6,727 ft | 3,750 ft | 2,820 ft | 4,230 ft |
| 35°C afternoon | 7,765 ft | 3,952 ft | 2,929 ft | 4,394 ft |
