Robbins Field serves Oneonta, Alabama at 1,140 ft elevation with its longest runway, 05/23, at 4,210 by 80 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 1,140 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)	1,140 ft	2,660 ft	2,230 ft	3,345 ft
Warm day (ISA +10)	2,340 ft	2,894 ft	2,357 ft	3,535 ft
Hot day (ISA +20)	3,540 ft	3,128 ft	2,483 ft	3,725 ft
35°C afternoon	3,814 ft	3,182 ft	2,512 ft	3,769 ft

Planning aid only. Even on a 35°C afternoon the longest runway (05/23, 4,210 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,769 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 K20A is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at K20A

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K20A, 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 K20A or read what a fuel stop actually saves.
