Cessna 172S Skyhawk preflight numbers at a glance: max gross weight 2550 lb, typical useful load 878 lb, 53 gal usable fuel, cruise up to about 124 KTAS (POH figure at 8000 ft, standard day). All figures below come from the FlightDecide curated aircraft library, digitized from the published POH/AFM. Use them for planning and study, and confirm against the POH for your specific serial number before flight.

Standard-day (ISA) rows shown, sampled across the POH table for readability; the FlightDecide app carries the full digitized table, including non-standard temperatures.
Book figures at 2550 lb, 0 ft pressure altitude, 15 °C. Real-world technique, wind, surface, and density altitude move these substantially, so apply your own margin (many pilots use 1.5× the book number) and run the numbers for the actual conditions.
| POH figure | Distance |
|---|---|
| Takeoff ground roll | 960 ft |
| Takeoff over a 50 ft obstacle | 1630 ft |
| Landing ground roll | 550 ft |
| Landing over a 50 ft obstacle | 1335 ft |
| Rate of climb | 730 fpm |

Common QuestionsPer the POH cruise table, up to about 124 KTAS at 8000 ft on a standard day, burning roughly 10.4 GPH at that setting. Typical everyday cruise settings run slower and leaner; see the table above.
53 gallons usable. At a high-cruise burn of 10.4 GPH that is roughly 5.1 hours to dry tanks. Plan with reserves, never to zero.
About 878 lb for a typically equipped example (2550 lb max gross minus a typical empty weight of 1672 lb). Your aircraft's actual empty weight and CG come from its own weight-and-balance records. Always use those, not type averages.
VNE (never exceed) is 163 kt and VNO (max structural cruising) is 129 kt. Full V-speed table above; verify against the POH for your serial.

FlightDecide ships this aircraft as a built-in profile: it computes your fuel, weight and balance, and takeoff/landing performance for the actual conditions, scores 8 risk categories against your personal minimums, and explains the result in plain language.
