A feature-complete autoflight suite, including full lateral and vertical guidance modes, RNAV/RNP-AR capabilities, and complex route construction supporting multiple ARINC424 leg types such as Radius to Fix (RF) legs are part of the A320’s arsenal of features. A “physical” fluid dynamic and air-mass simulation is modelled, with thousands of working components from control computers to individual mix valves for the pneumatic system, represented – and all wired to their respective power source/networks on the aircraft, for an truly in-depth simulation.
