Knox County Regional Airport serves Rockland, Maine at 56 ft elevation with its longest runway, 13/31, at 5,412 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 56 ft is about 15°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, 15°C)	56 ft	2,449 ft	2,116 ft	3,174 ft
Warm day (ISA +10)	1,256 ft	2,683 ft	2,243 ft	3,364 ft
Hot day (ISA +20)	2,456 ft	2,917 ft	2,369 ft	3,554 ft
35°C afternoon	2,469 ft	2,920 ft	2,370 ft	3,556 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 5,412 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,556 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 KRKD is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KRKD

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