Alta Vista Ranch Airport serves Marfa, Texas at 4,702 ft elevation with its longest runway, 12/30, at 5,200 by 100 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
12/30	5,200 × 100 ft	asphalt	lit
15/33	5,100 × 100 ft	turf	unlit
05/23	5,000 × 100 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 4,702 ft is about 6°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, 6°C)	4,702 ft	3,355 ft	2,606 ft	3,909 ft
Warm day (ISA +10)	5,902 ft	3,589 ft	2,733 ft	4,099 ft
Hot day (ISA +20)	7,102 ft	3,823 ft	2,859 ft	4,289 ft
35°C afternoon	8,230 ft	4,043 ft	2,978 ft	4,467 ft

Planning aid only. Even on a 35°C afternoon the longest runway (12/30, 5,200 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,467 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 0TA7 is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at 0TA7

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at 0TA7, 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 0TA7 or read what a fuel stop actually saves.
