Our Boeings are set to call displayed minima as selected on the MCP (Mode Control Panel in the middle just under the glareshield) only if the minima is displayed on the PFD (Primary Flight Display). This applies to Baro and Rad Alt.
The call is '50 Above' followed by 'Decide'. In low visibility it allows the landing pilot to be 'heads out' looking for the required visual references for the approach whilst also making the call to 'continue' or 'Go-Around' at decision height which the pilot flying the approach would then initiate.
