Washington Dulles International Airport serves Dulles, Virginia at 312 ft elevation with its longest runway, 01C/19C, at 11,500 by 150 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 312 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)	312 ft	2,499 ft	2,143 ft	3,214 ft
Warm day (ISA +10)	1,512 ft	2,733 ft	2,270 ft	3,404 ft
Hot day (ISA +20)	2,712 ft	2,967 ft	2,396 ft	3,594 ft
35°C afternoon	2,787 ft	2,982 ft	2,404 ft	3,606 ft

Planning aid only. Even on a 35°C afternoon the longest runway (01C/19C, 11,500 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,606 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 KIAD is high, or as the longer runway on a hot afternoon.

Airport	Distance	Longest runway
KJYO Leesburg Executive Airport	9 nm NW	5,500 ft
KHEF Washington Manassas Harry P. Davis Field	14 nm S	6,200 ft
2VG2 Upperville Airport	19 nm W	5,100 ft
KDCA Ronald Reagan Washington National Airport	20 nm E	7,169 ft

04Jet A prices and FBOs at KIAD

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