ATC has cut you in short .... you have the speedbrake up, retractable landing lights extended and gear down. Short of throwing out an anchor this beast will not go down any faster or slow down any quicker. All the while you are constantly doing your 3 times tables (maybe even adding a bit or subtracting also), doing the landing checklist, most probably have a frequency change and you want to make a PA ?!?!? Do you walk to work with a broom up your @rse so you can sweep the sidewalk at the same time? Didn't think so. Guess when I become more comfortable I'll have more time to do the housekeeping and make a PA!
