Cascade Airport serves Cascade, Idaho at 4,742 ft elevation with its longest runway, 12/30, at 4,300 by 60 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 4,742 ft is about 6°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, 6°C)	4,742 ft	3,363 ft	2,610 ft	3,915 ft
Warm day (ISA +10)	5,942 ft	3,597 ft	2,737 ft	4,105 ft
Hot day (ISA +20)	7,142 ft	3,831 ft	2,863 ft	4,295 ft
35°C afternoon	8,280 ft	4,053 ft	2,984 ft	4,475 ft

Planning aid only. On a 35°C afternoon the longest runway (12/30, 4,300 ft) is within 20 percent of the 1.5x landing figure for a Meridian-class turboprop (4,475 ft). Plan hot-day departures for the morning and check the POH. 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 KU70 is high, or as the longer runway on a hot afternoon.
