OEB137/1, was issued in Sep98, concerns the non availability of alternate brakes due to water freezing in the BDDV valve cover. The airbus recommendation was, "if the autobrake is to be used at landing:
-Before landing gear extension:
-Appropriate autobrake mode.....SELECT
-Press the autobrake pushbutton firmly for at least 1 second to ensure that the autobrake system is properly armed."
The remainder of the procedure concerns the BSCU resets. Also the BDDV valve covers have been fixed so as to preclude water freezing in them.
