Dear all, I've noticed that "minimum" callout is false. Exemple: If I enter "1500" in the MDA FMS box, and the THR altitude is 1300ft, the callout will trigger at 1500ft AGL (2800ft AMSL) instead of 1500ft AMSL. My opinion is that whatever you put your barometric minima into MDA or RA box, the callout will be based on the radio altimeter probe. Thanks for your answer. Regards.
