The poster said these were ATC transmissions, not internal company
communications. Since ATC doesn't concern itself with weight, balance,
or any other flight performance factors, your explanation is almost
certainly wrong.

ATC does, however, need to know if the pilot has the current ATIS
(Automated Terminal Information Service) information: ceiling,
visibility, wind, altimeter setting, runway in use, and any special
airport information.


The KGRB ATIS includes a statement advising air carrier aircraft to
make sure they have their numbers before calling ready for taxi. It
was added because Northwest became notorious for taxiing without them
and blocking other departures while they waited for them.
