Hmm, I am not sure if that is the best idea. MC value displayed on the overlay is also strictly connected to the STF value. I may want to know STF for 0 MC even if safety is set to 0,5. When the interface will not allow the pilot to set lower values than the Safety MC than that value again will not be a safety value because it will be on the border of the envelope.
I think we are saying a different thing, Mat. When looking at the MC overlay, if the arrival altitude below is relative to a safetyMC which is lower than the one overprinted, then we should tell . Like we do for safety altitude, basically. Without changing anything else. Only a small box like for +300m , in my case.
