Muir Army Air Field (Fort Indiantown Gap) Airport serves Fort Indiantown Gap(Annville), Pennsylvania at 488 ft elevation with its longest runway, 07/25, at 3,981 by 98 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 488 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)	488 ft	2,533 ft	2,161 ft	3,242 ft
Warm day (ISA +10)	1,688 ft	2,767 ft	2,288 ft	3,432 ft
Hot day (ISA +20)	2,888 ft	3,001 ft	2,415 ft	3,622 ft
35°C afternoon	3,005 ft	3,024 ft	2,427 ft	3,641 ft

Planning aid only. Even on a 35°C afternoon the longest runway (07/25, 3,981 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,641 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.
