In the ever evolving steps towards safety, Runway Overrun Prevention Systems (ROPS), the Step 3 introduces RCDF (an aircraft level Runway Condition Downgrading Function).

The computation of stopping distance (ROP distance) is modified to include a low anti-skid activity Boolean per wheel in order to feed the RCDF.

ROPS will now also have software based inhibitions. Standard on the XLR, this will be available to the entire A320 Family.
