Sky Harbor Airport serves Duluth, Minnesota at 610 ft elevation with its longest runway, 13W/31W, at 10,000 by 2,000 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
13W/31W	10,000 × 2,000 ft	water	unlit
09W/27W	5,000 × 1,500 ft	water	unlit
14/32	2,602 × 75 ft	asphalt	lit

02Density altitude and turboprop runway margins

Standard temperature at 610 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)	610 ft	2,557 ft	2,174 ft	3,262 ft
Warm day (ISA +10)	1,810 ft	2,791 ft	2,301 ft	3,451 ft
Hot day (ISA +20)	3,010 ft	3,025 ft	2,428 ft	3,641 ft
35°C afternoon	3,156 ft	3,054 ft	2,443 ft	3,664 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13W/31W, 10,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,664 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 KDYT is high, or as the longer runway on a hot afternoon.

KDLH Duluth International Airport	10 nm NW	10,591 ft
KASX John F Kennedy Memorial Airport	48 nm E	5,197 ft

04Jet A prices and FBOs at KDYT

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