AIR LAB · HOI4 1.19.3
Compare plane designs without pretending the air model is solved
Air Lab uses retained 1.19.3 aircraft data and a bounded combat model. It is useful for controlled comparisons, but it does not present modeled losses as exact executable output.
Build the aircraft
Pick an airframe and compatible modules, then compare speed, agility, air attack, air defense, range and mission stats. The designer uses the retained 1.19.3 airframe, module and slot data where certified.
Keep the test controlled
Compare two built aircraft under the same mission assumptions. Keep the opponent and mission fixed, change one feature, and see whether the modeled exchange moves.
Know what the result means
Source-backed aircraft values are stronger evidence than the current dogfight model. Engagement, speed/agility interactions and other executable-only behavior remain bounded rather than treated as exact. Weather, night behavior, accidents, detailed wing scheduling and several operational air systems are outside the certified model.
Accuracy boundary
Airframe and module values are source-certified where retained. Parts of the combat model remain executable inferred until Oracle testing can narrow them further. See methodology for the evidence classes.
