John C Tune Airport serves Nashville, Tennessee at 495 ft elevation with its longest runway, 02/20, at 6,001 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.

02Density altitude and turboprop runway margins

Standard temperature at 495 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)	495 ft	2,535 ft	2,162 ft	3,243 ft
Warm day (ISA +10)	1,695 ft	2,769 ft	2,289 ft	3,433 ft
Hot day (ISA +20)	2,895 ft	3,003 ft	2,415 ft	3,623 ft
35°C afternoon	3,014 ft	3,026 ft	2,428 ft	3,642 ft

Planning aid only. Even on a 35°C afternoon the longest runway (02/20, 6,001 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,642 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 KJWN is high, or as the longer runway on a hot afternoon.
