01Runways

Runway	Length × width	Surface	Lighting

02Density altitude and turboprop runway margins

Standard temperature at 3,413 ft is about 8°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, 8°C)	3,413 ft	3,104 ft	2,470 ft	3,705 ft
Warm day (ISA +10)	4,613 ft	3,338 ft	2,597 ft	3,895 ft
Hot day (ISA +20)	5,813 ft	3,572 ft	2,723 ft	4,085 ft
35°C afternoon	6,632 ft	3,732 ft	2,810 ft	4,215 ft

Planning aid only. Even on a 35°C afternoon the longest runway (14/32, 5,200 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,215 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 KSYF is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KSYF

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