In the FlightDecide app since 2026-07-16. Not yet reviewed against the handbook. 0 of 6 tables from the handbook. Anything marked “Not yet verified against the handbook” comes from FlightDecide's earlier library and hasn't been checked against the printed page.
Piper PA-34 Seneca preflight numbers at a glance: max gross weight 4570 lb, typical useful load 1670 lb, 93 gal usable fuel, cruise up to about 187.8 KTAS (reference figure at 10,000 ft, standard day). Figures below come from the FlightDecide curated aircraft library. The performance tables for this type have not yet been re-checked against the handbook, so treat them as estimates. Use them for planning and study, and confirm against the POH for your specific serial number before flight.

Estimated figures at 4570 lb, 0 ft pressure altitude, 15 °C. These have not yet been re-checked against the handbook. 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.
| Estimated figure | Distance |
|---|---|
| Takeoff ground roll | 1240 ft |
| Takeoff over a 50 ft obstacle | 1800 ft |
| Landing ground roll | 580 ft |
| Landing over a 50 ft obstacle | 985 ft |
| Rate of climb | 1340 fpm |

Common QuestionsPer the library's cruise table, not yet verified against the handbook, up to about 187.8 KTAS at 10,000 ft on a standard day, burning roughly 22 GPH at that setting. Typical everyday cruise settings run slower and leaner; see the table above.
93 gallons usable. At a high-cruise burn of 22 GPH that is roughly 4.2 hours to dry tanks. Plan with reserves, never to zero.
About 1670 lb for a typically equipped example (4570 lb max gross minus a typical empty weight of 2900 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 195 kt and VNO (max structural cruising) is 163 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.
