Madras Municipal Airport serves Madras, Oregon at 2,437 ft elevation with its longest runway, 16/34, at 5,091 by 75 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

02Density altitude and turboprop runway margins

Standard temperature at 2,437 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)	2,437 ft	2,913 ft	2,367 ft	3,551 ft
Warm day (ISA +10)	3,637 ft	3,147 ft	2,494 ft	3,741 ft
Hot day (ISA +20)	4,837 ft	3,381 ft	2,620 ft	3,930 ft
35°C afternoon	5,422 ft	3,496 ft	2,682 ft	4,023 ft

Planning aid only. Even on a 35°C afternoon the longest runway (16/34, 5,091 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,023 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 KS33 is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KS33

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KS33, 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 KS33 or read what a fuel stop actually saves.
