Hmm..let's see here...you are in the Slob? Is that right - um - is it Captain..? So you're saying that you have NEVER said anything below 10,000 ft other than REQUIRED CHECKLIST ITEMS, ATC COMMO, OR REQUIRED CALLOUTS, is that correct...?
Umm...the sterile cockpit concept allows you to vocalize more than just these three items. Issues that are directly related to the safe outcome of the flight can and should be discussed:
"That's a pretty big thunderstorm right in front of us" or
"That airplane looks pretty close to us" or
"Let's review the missed approach procedure one more time" or
"Let's review the windshear recovery procedure" etc.
