Tri Cities Airport serves Pasco, Washington at 410 ft elevation with its longest runway, 03L/21R, at 7,707 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
03L/21R	7,707 × 150 ft	asphalt	lit

03R/21L	4,423 × 75 ft	asphalt	unlit

02Density altitude and turboprop runway margins

Standard temperature at 410 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)	410 ft	2,518 ft	2,153 ft	3,230 ft
Warm day (ISA +10)	1,610 ft	2,752 ft	2,280 ft	3,420 ft
Hot day (ISA +20)	2,810 ft	2,986 ft	2,406 ft	3,610 ft
35°C afternoon	2,908 ft	3,005 ft	2,417 ft	3,625 ft

Planning aid only. Even on a 35°C afternoon the longest runway (03L/21R, 7,707 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,625 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 KPSC is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KPSC

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