A briefing committed to memory: This will be a Cat IIIa approach using an RA based DH of 50′. We will need to see Cat III single, or better, on the FMA. When you see LAND on the FMA call “land green”. If it does not annunciate by 350′ RA then call “missed approach”. Altitude call outs will be automatic. At the 100′ call I will say “checked” and you will continue to monitor the FMA and your instruments. At the “minimums” call one of two things will happen. If I am able to visually verify the landing environment, I will say “landing” and the autopilot will autoland the airplane. If I am unable to verify the landing environment then I will push the thrust levers to TOGA and announce “TOGA GO-AROUND FLAPS” and the aircraft will execute a go around.
