Memphis Municipal Airport serves Memphis, Texas at 2,102 ft elevation with its longest runway, 17/35, at 4,670 by 75 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
17/35	4,670 × 75 ft	asphalt	lit
08/26	2,750 × 70 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 2,102 ft is about 11°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, 11°C)	2,102 ft	2,848 ft	2,332 ft	3,498 ft
Warm day (ISA +10)	3,302 ft	3,082 ft	2,458 ft	3,688 ft
Hot day (ISA +20)	4,502 ft	3,316 ft	2,585 ft	3,877 ft
35°C afternoon	5,006 ft	3,414 ft	2,638 ft	3,957 ft

Planning aid only. Even on a 35°C afternoon the longest runway (17/35, 4,670 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,957 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 KF21 is high, or as the longer runway on a hot afternoon.
