M29 · Hassell Field
Hassell Field serves Clifton, Tennessee at 401 ft elevation with its longest runway, 02/20, at 4,600 by 75 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.

01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 02/20 | 4,600 × 75 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 401 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) | 401 ft | 2,516 ft | 2,152 ft | 3,228 ft |
| Warm day (ISA +10) | 1,601 ft | 2,750 ft | 2,279 ft | 3,418 ft |
| Hot day (ISA +20) | 2,801 ft | 2,984 ft | 2,406 ft | 3,608 ft |
| 35°C afternoon | 2,897 ft | 3,003 ft | 2,416 ft | 3,623 ft |

04Jet A prices and FBOs at M29
No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at M29, 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.
