Northeast Florida Regional Airport serves St Augustine, Florida at 10 ft elevation with its longest runway, 17W/35W, at 12,000 by 1,000 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 10 ft is about 15°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, 15°C)	10 ft	2,440 ft	2,111 ft	3,167 ft
Warm day (ISA +10)	1,210 ft	2,674 ft	2,238 ft	3,356 ft
Hot day (ISA +20)	2,410 ft	2,908 ft	2,364 ft	3,546 ft
35°C afternoon	2,412 ft	2,908 ft	2,364 ft	3,547 ft

Planning aid only. Even on a 35°C afternoon the longest runway (17W/35W, 12,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,547 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 KSGJ is high, or as the longer runway on a hot afternoon.

Airport	Distance	Longest runway
FD48 Deep Forest Airport	18 nm N	6,425 ft
K28J Palatka Municipal - Lt. Kay Larkin Field	26 nm SW	6,000 ft
KFIN Flagler Executive Airport	30 nm S	5,500 ft

04Jet A prices and FBOs at KSGJ

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