01Runways

Runway	Length × width	Surface	Lighting

8/26	6,953 × 75 ft	asphalt	unlit

02Density altitude and turboprop runway margins

Standard temperature at 3,939 ft is about 7°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, 7°C)	3,939 ft	3,206 ft	2,526 ft	3,788 ft
Warm day (ISA +10)	5,139 ft	3,440 ft	2,652 ft	3,978 ft
Hot day (ISA +20)	6,339 ft	3,674 ft	2,779 ft	4,168 ft
35°C afternoon	7,284 ft	3,859 ft	2,878 ft	4,318 ft

Planning aid only. Even on a 35°C afternoon the longest runway (16/34, 7,003 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,318 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 KGEY is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KGEY

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