02Density altitude and turboprop runway margins

Standard temperature at 722 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)	722 ft	2,579 ft	2,186 ft	3,279 ft
Warm day (ISA +10)	1,922 ft	2,813 ft	2,313 ft	3,469 ft
Hot day (ISA +20)	3,122 ft	3,047 ft	2,439 ft	3,659 ft
35°C afternoon	3,295 ft	3,081 ft	2,458 ft	3,686 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 6,501 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,686 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 KMTO is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KMTO

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