While dogfighting with the AI Anton in single-player, I became suspicious the Anton was catching up to the Spit when, according the max level performance for the two a/c, the Spit should not be caught during level flight at altitudes greater than 4000 feet. Gathered data on both the Spit and 190 in the Mission Editor to compare max level performance and came up with familiar looking results. At roughly 22,000ft, max TAS for the Spit is 379mph (330kts) vs. 365mph (317kts) for the Anton. Ran both aircraft in the Mission Editor and flew the Spit directly in front of the AI Anton at 22,000ft. The Anton speed was set to 317kts TAS and configured as a Task = Fighter Sweep to encourage it to chase. According to the DCS model for the non-AI Anton, the a/c should not go faster. However, the Anton speeds up to 341kts TAS to overtake the Spit and starts shooting. I couldn’t find any other post covering the topic and wonder if anyone else has had similar observation.
