Check Airman I disagree
yes, In some cases distractions can interrupt a flow or cause you to miss a minor item...that shouldn't kill anyone
But IMHO if it's critical Item in an extremely critical but optional phase of flight---You make sure you check those critical items, if you have to re-run a check list then you do...but Pitot heat,if not automatic, Anti Ice pressuriztion performance or whatever else may kill you must never be comprimised just to make a takeoff---up aginst slots and duty time limitations? oh well company's problem better late than dead---
Now right before a takeoff we know that there are three well known killers--- airmanship dictates that you STOP THAT AIRPLANE!!! and check them...whether you miss your slot, or not...we've repeated these mistakes long enough to know they can be unforgiving...
WE NEED TO JUST STOP!
