Hi I understand pilots use this feature for MDH, Incases of ILS CAT II radio minima is used so say in a 737ng landing in Cork on RWY17 the pilot would set the radio minima to 60 (The RDH being 57) if below CAT II he will use baro minima which usually is around 200ft AGL so let's say at Cork that would be 700ft for baro minima. I find this easy to understand however I noticed during a turnaround today a BARO setting which I can't remember was displayed on the PFD, the plane was departing and the setting was in the thousands, my question is what is baro setting on departure used for and what is it set to, also would it vary like approach minima's?
Would appreciate a response, thank you!
