Ed Carlson Memorial Field South Lewis County Airport serves Toledo, Washington at 374 ft elevation with its longest runway, 06/24, at 4,479 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 374 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)	374 ft	2,511 ft	2,149 ft	3,224 ft
Warm day (ISA +10)	1,574 ft	2,745 ft	2,276 ft	3,414 ft
Hot day (ISA +20)	2,774 ft	2,979 ft	2,403 ft	3,604 ft
35°C afternoon	2,864 ft	2,997 ft	2,412 ft	3,618 ft

Planning aid only. Even on a 35°C afternoon the longest runway (06/24, 4,479 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,618 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 KTDO is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KTDO

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