EIU-EEC,
Thanks. Yes, 2 LAF accumulators (Green and Yellow) per side makes sense. Spoilers 4 use Yellow, Spoilers 5 use Green, and Ailerons use Green (as well as Blue).
Quote from mono:
"However it would be a software function only. No additional hardware (accumulators) would be required."
How could it work without hardware, incuding accumulators? It has to be lightning-fast: much faster than the normal control inputs. Perhaps it means "additional to the existing"?
Since LAF software was discontinued, have A320s continued to be made with some or all of the hardware, including the accumulators? If not, that information you quote doesn't make sense.
