Felts Field serves Spokane, Washington at 1,953 ft elevation with its longest runway, 3W/21W, at 6,000 by 100 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
3W/21W	6,000 × 100 ft	water	unlit
4L/22R	4,500 × 150 ft	concrete	lit
4R/22L	2,650 × 75 ft	asphalt	lit

02Density altitude and turboprop runway margins

Standard temperature at 1,953 ft is about 11°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, 11°C)	1,953 ft	2,819 ft	2,316 ft	3,474 ft
Warm day (ISA +10)	3,153 ft	3,053 ft	2,443 ft	3,664 ft
Hot day (ISA +20)	4,353 ft	3,287 ft	2,569 ft	3,854 ft
35°C afternoon	4,822 ft	3,378 ft	2,619 ft	3,928 ft

Planning aid only. Even on a 35°C afternoon the longest runway (3W/21W, 6,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,928 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 KSFF is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KSFF

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KSFF, 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 KSFF or read what a fuel stop actually saves.
