Check out an emulation solution for Airbus Flight Management on a personal computer. Work with a set of settings and options for managing various functions and features of the simulation, such as autopilot overriding motion controls, and programmable sequences.
vasFMC is a Open-Source project, which develops an Airbus Flight Managment Computer.
vasFMC is compatible with FSX, brings an Airbus like autopilot overriding the default one of the sim, adds various pages and features compared to the previous version. So you have an Airbus FMGC or Boeing FMS for aircraft add-ons that don’t carry such advanced systems.
