01Runways

Runway	Length × width	Surface	Lighting
13/31	4,210 × 75 ft	asphalt	lit
01/19	2,034 × 120 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 1,318 ft is about 12°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, 12°C)	1,318 ft	2,695 ft	2,249 ft	3,374 ft
Warm day (ISA +10)	2,518 ft	2,929 ft	2,376 ft	3,563 ft
Hot day (ISA +20)	3,718 ft	3,163 ft	2,502 ft	3,753 ft
35°C afternoon	4,034 ft	3,225 ft	2,536 ft	3,803 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 4,210 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,803 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 KBTN is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KBTN

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