A320 RA 1+2 Fault
In the A320 in the case of RA 1+2 Fault the Approach cannot be armed. So in case we need to do an ILS approach, the option is to either switch off the FDs and fly the ILS raw data or use the FDs by selecting V/S.
My doubt is this: In case we are following the FDs using the V/S selector knob should we use the minima (visibility) applicable for FDs available or FDs not available as it is not as precise as arming the approach.
