POH-based planning aid only — not for operational use. Values are computed from the selected aircraft's POH performance tables and aircraft-specific weight & balance data. The pilot in command is solely responsible for verifying all calculations against the current POH, AFM, and applicable regulations before flight.

About the Diamond DA20-A1 Katana

First production year (approx.): 1994.

The Diamond DA20-A1 Katana was an early composite two-seater in Diamond's trainer line, preceding the IO-240 powered C1 Eclipse.

Clubs still operate A1 airframes. Confirm engine variant and AFM edition before relying on these performance numbers.
