Rosecrans Memorial Airport serves St Joseph, Missouri at 826 ft elevation with its longest runway, 17/35, at 8,061 by 150 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.

02Density altitude and turboprop runway margins

Standard temperature at 826 ft is about 13°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, 13°C)	826 ft	2,599 ft	2,197 ft	3,296 ft
Warm day (ISA +10)	2,026 ft	2,833 ft	2,324 ft	3,486 ft
Hot day (ISA +20)	3,226 ft	3,067 ft	2,450 ft	3,676 ft
35°C afternoon	3,424 ft	3,106 ft	2,471 ft	3,707 ft

Planning aid only. Even on a 35°C afternoon the longest runway (17/35, 8,061 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,707 ft needed). The percentages are a generic rule of thumb applied to one reference airplane, not certified performance data for any specific aircraft, and the runway size categories describe the runway, not your airplane's suitability. Verify with the approved flight manual before every flight.

03Nearby fields with 5,000 ft or more

Useful as alternates, as fuel stops when the price at KSTJ is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KSTJ

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KSTJ, the app flags a price stale after two weeks, and the route finder ranks every field within a corridor of your route by net savings after the cost of the extra cycle. Log a price at KSTJ or read what a fuel stop actually saves.
