2. System description

Kaila is an end-to-end training system for UHF television transmitter facilities. The operator enters a facility representation, occupies the control position, and exercises plant procedures under a live physics model.

Presentation and authority are separated. Unreal renders world, console, and HUD. Python owns RF chains, amplifier models, instruments math, scenarios, and optional GPU kernels. RF math is not reimplemented in Blueprints.
