John Murtha Johnstown Cambria County Airport serves Johnstown, Pennsylvania at 2,284 ft elevation with its longest runway, 15/33, at 7,004 by 150 ft.

02Density altitude and turboprop runway margins

Standard temperature at 2,284 ft is about 10°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, 10°C)	2,284 ft	2,883 ft	2,351 ft	3,526 ft
Warm day (ISA +10)	3,484 ft	3,118 ft	2,478 ft	3,716 ft
Hot day (ISA +20)	4,684 ft	3,352 ft	2,604 ft	3,906 ft
35°C afternoon	5,232 ft	3,458 ft	2,662 ft	3,993 ft

Planning aid only. Even on a 35°C afternoon the longest runway (15/33, 7,004 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,993 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 KJST is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KJST

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