Aircraft; Weather
MEL's 34-2X-XX No 1 radio altimeter; 34-1X-XX Windshear Detection; 46-X-XX OPC Computer. MEL 25-XX-XX. Left late due to weight restrictions. The alternate was changed and cargo removed to allow for standby Passengers. Captain was Pilot Flying. Crew briefed MEL 34-2X-XX; noting that the flight director would not be used. Captain did not brief that autopilot would turn off when approach was selected. On arrival; airport switched arrival and runway due to frontal passage. Briefed new arrival and approach. Multiple messages from Dispatch on arrival for alternate info and landing data due to OPC inoperative (MEL 46-X-XX). We are now computed to be 1;000 pounds overweight for landing due to shortened route. Captain chose to lower landing gear at 9;000 feet on arrival. When slowed to 180 knots; selected flaps 15 at 20 miles out to increase drag. Wind was from the south; 45 knot crosswind in heavy rain. Outside of FAF; Pilot Flying (PF) selected VOR/ILS on nav select switch. ILS data was looking good and PF selected Approach Mode on MCP. Upon selection; flight directors went away and autopilot turned off. PF turned on autopilot B after diagnosing problem. During the time it took to select AP B; aircraft drifted right of course due to 45 knot crosswind. Executed missed approach. Transferred control to First Officer (FO) for ILS. Landed uneventfully.
