02Density altitude and turboprop runway margins

Standard temperature at 1,146 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)	1,146 ft	2,662 ft	2,231 ft	3,346 ft
Warm day (ISA +10)	2,346 ft	2,896 ft	2,358 ft	3,536 ft
Hot day (ISA +20)	3,546 ft	3,130 ft	2,484 ft	3,726 ft
35°C afternoon	3,821 ft	3,183 ft	2,513 ft	3,770 ft

Planning aid only. Even on a 35°C afternoon the longest runway (12/30, 4,105 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,770 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 KVMR is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KVMR

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KVMR, 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.
