Baltimore/Washington International Thurgood Marshall Airport serves Baltimore, Maryland at 146 ft elevation with its longest runway, 10/28, at 10,503 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.

Runway	Length × width	Surface	Lighting
10/28	10,503 × 150 ft	asphalt	lit

15L/33R	5,000 × 100 ft	asphalt	lit

02Density altitude and turboprop runway margins

Standard temperature at 146 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)	146 ft	2,466 ft	2,125 ft	3,188 ft
Warm day (ISA +10)	1,346 ft	2,701 ft	2,252 ft	3,378 ft
Hot day (ISA +20)	2,546 ft	2,935 ft	2,379 ft	3,568 ft
35°C afternoon	2,581 ft	2,941 ft	2,382 ft	3,573 ft

Planning aid only. Even on a 35°C afternoon the longest runway (10/28, 10,503 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,573 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 KBWI is high, or as the longer runway on a hot afternoon.

Airport	Distance	Longest runway
KMTN Martin State Airport	15 nm NE	6,999 ft
KDCA Ronald Reagan Washington National Airport	26 nm SW	7,169 ft
KDMW Carroll County Regional Jack B Poage Field	30 nm NW	5,100 ft
KESN Easton Airport / Newnam Field	36 nm SE	5,500 ft

04Jet A prices and FBOs at KBWI

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