In the FlightDecide app since 2026-07-16. Reviewed 2026-09-28. 1 of 7 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.

Diamond DA20-C1 Eclipse preflight numbers at a glance: max gross weight 1764 lb, typical useful load 614 lb, 24 gal usable fuel, cruise up to about 129 KTAS (reference figure at 2000 ft, standard day). 1 of the 7 performance tables below is read from the published POH/AFM and cites its figure and page; treat the ones marked “Not yet verified against the handbook” as estimates. Use them for planning and study, and confirm against the POH for your specific serial number before flight.

How much runway does a Diamond DA20-C1 Eclipse need?

Not yet verified against the handbook

Estimated figures at 1764 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 figureDistance
Takeoff ground roll1100 ft
Takeoff over a 50 ft obstacle1650 ft
Landing ground roll415 ft
Landing over a 50 ft obstacle705 ft
Rate of climb730 fpm

Stall speeds

Idle, most forward center of gravity, max. weight of 800 kg (1764 lb) - the handbook calls this the most adverse configuration. Speeds in knots; the flap settings are the DA 20-C1's three flap-selector positions, printed on this sheet as Cruise / Take-off / Landing and elsewhere in the manual as CRUISE / T/O / LDG.

Common Questions

Per the library's cruise table, not yet verified against the handbook, up to about 129 KTAS at 2000 ft on a standard day, burning roughly 8.7 GPH at that setting. Typical everyday cruise settings run slower and leaner; see the table above.

24 gallons usable. At a high-cruise burn of 8.7 GPH that is roughly 2.8 hours to dry tanks. Plan with reserves, never to zero.

About 614 lb for a typically equipped example (1764 lb max gross minus a typical empty weight of 1150 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 164 kt and VNO (max structural cruising) is 118 kt. Full V-speed table above; verify against the POH for your serial.
