01Runways

Runway	Length × width	Surface	Lighting
09/27	4,300 × 75 ft	asphalt	lit
18/36	4,261 × 340 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 818 ft is about 13°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, 13°C)	818 ft	2,598 ft	2,196 ft	3,294 ft
Warm day (ISA +10)	2,018 ft	2,832 ft	2,323 ft	3,484 ft
Hot day (ISA +20)	3,218 ft	3,066 ft	2,449 ft	3,674 ft
35°C afternoon	3,414 ft	3,104 ft	2,470 ft	3,705 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 4,300 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,705 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 Y70 is high, or as the longer runway on a hot afternoon.
