It’s really good to see that CRM (Courtesy Respect Manners) is alive and well.
From reading all of the above, I wouldn’t hestitate to do the safest thing as there is no time to discuss with the other pilot any other options when that close to the ground (Aural Alerts while the Rad Alt is active).
Too much crossing the (t’s) and dotting the (i’s) above for me. Here I see a typical case of aviation today sadly, discussing systems and procedures when being a pilot and looking out the window would have been the best procedure to follow to prevent this incident.
New Years Resolution for this site should be that only positive discussion and feedback and admitting when you are wrong. If you are correct then put the point across in a way that ensures others understand you and leaves them no doubt. Having heated discussions tends to leave people like me to abandon reading a specific thread.
Have a good Crimbo and a SAFE and Happy New Year All.
