Not true. This is why the ELACs, SECs and FACs are duplicated with functional redundancy across all six units. HAL is a *bad* analogy because it implies a centralised decision-making apparatus, when in fact it is distributed and redundant.
This includes one where the flight deck crew initiated a go around because they were not happy with the aircraft on the ground encroaching to close to the runway.
Was that HAL, or were the pilots flying the aircraft?
Could have been either. If autopilot and autothrust are engaged and the FMC is properly set up, a TOGA command will cause it to fly the escape/go-around procedure automatically. If the approach is manual the pilots can either do it off their own back or follow the FD.
