North Texas Regional Airport Perrin Field serves Denison, Texas at 749 ft elevation with its longest runway, 18L/36R, at 9,000 by 150 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.

01Runways

Runway	Length × width	Surface	Lighting
18L/36R	9,000 × 150 ft	asphalt (PEM)	lit
18R/36L	4,008 × 100 ft	asphalt	unlit

02Density altitude and turboprop runway margins

Standard temperature at 749 ft is about 14°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, 14°C)	749 ft	2,584 ft	2,189 ft	3,284 ft
Warm day (ISA +10)	1,949 ft	2,818 ft	2,316 ft	3,473 ft
Hot day (ISA +20)	3,149 ft	3,052 ft	2,442 ft	3,663 ft
35°C afternoon	3,329 ft	3,087 ft	2,461 ft	3,692 ft

Planning aid only. Even on a 35°C afternoon the longest runway (18L/36R, 9,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,692 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 KGYI is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KGYI

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