ACR FO EXPRESSES CONCERN WITH ATC COM CLRNC DURING ROLLOUT.

Narrative

ONE AREA OF COM THAT HAS NOT RECEIVED A GREAT DEAL OF PUBLICIZED EMPHASIS WITH REGARDS TO RWY INCURSIONS IS THAT OF RECEIVED BY THE FLC'S FROM THE TWR ON LNDG ROLL. ON LNDG ROLL; THE ACFT IS BEING BROUGHT TO A STOP BY THE FLC; CALLOUTS ARE BEING MADE; THRUST REVERSERS; BRAKES AND SPOILERS ARE BEING USED; AND IT IS VERY NOISY AND BUSY. THE LAST THING THAT NEEDS TO BE ADDED TO ALL THAT CONFUSION IS A CALL FROM THE TWR DIRECTING US WHERE TO CLR; WHAT FREQ TO USE FOR GND; AND WHAT; IF ANY; RWY WE ARE TO HOLD SHORT OF OR TAXI ACROSS. AS A PERSONAL RULE; I IGNORE ALL XMISSIONS FROM THE TWR UNTIL WE ARE A SAFE TAXI SPD; THEN I ASK FOR THE COM TO BE REPEATED. GENERALLY; THIS IS NOT A PROB; BUT SOME CTLRS BECOME OBVIOUSLY AGITATED AT HAVING TO REPEAT THEMSELVES. ALL CLRNCS FROM ATC TO WHICH I RESPOND ARE; IN EFFECT; REGULATORY IN NATURE. DURING LNDG ROLL; I AM NOT IN A POS TO ADEQUATELY DETERMINE WHAT WAS SAID; OR WHETHER WE ARE EVEN ABLE TO COMPLY. IT IS SIMPLY TOO BUSY A TIME TO BE COMMUNICATING ON THE RADIO. I BELIEVE THIS PERIOD OF TIME NEEDS TO BE QUIET OVER THE RADIO; UNLESS THERE IS AN 'URGENT' NEED FOR THE TWR TO TALK TO US. I HAVE SPOKEN TO TWR CTLRS REGARDING THIS ISSUE; AND; SURPRISINGLY; MOST ARE COMPLETELY UNAWARE OF THIS PROB. ON THAT SAME NOTE; MOST ARE QUITE UNDERSTANDING WHEN IT IS BROUGHT TO THEIR ATTN.
