C90 APCH CTLR RESPONDS UNPROFESSIONALLY TO S80 FLC WHEN HE CHALLENGES ACFT 'SLOWER THAN EXPECTED' DSCNT RATE.

Narrative

WE WERE WORKING WITH ORD APCH CTL ON L DOWNWIND TO RWY 27L. WE WERE IN ICING AND HAD TO MAINTAIN A HIGHER PWR SETTING TO SUPPLY THE ANTI-ICE EQUIP. DESPITE THE FACT THAT WE HAD ALL AVAILABLE DRAG DEVICES IN USE; WE WERE NOT DSNDING RAPIDLY ENOUGH TO SUIT THE CTLR; SO; HE ANGRILY SNAPPED; 'GET DOWN TO FIVE THOUSAND. I'VE GOT TFC.' WE WERE MAINTAINING 800 FPM AT THE TIME; WHICH WAS THE BEST WE COULD DO. AT ABOUT THE SAME TIME; WE FLEW OUT OF THE CLOUD ASSOCIATED WITH THE ICING; SO WE WERE ABLE TO PULL THE PWR OFF AND INCREASE OUR DSCNT RATE. IT CLRLY MUST HAVE SEEMED THAT WE WERE ABLE TO COMPLY JUST BECAUSE HE TOLD US TO. A LONG EXPLANATION WOULD HAVE BEEN AS INAPPROPRIATE AS AN ANGRY RETORT; BECAUSE HE WAS VERY BUSY. IT WOULD HAVE BEEN A DISTR TO HIM; PROBABLY AS DISTRACTING AS HIS TREATMENT OF US WAS TO ME AS I FLEW THE REST OF THE APCH AND LNDG IN CHALLENGING WIND CONDITIONS. ANGER RESULTS IN ANGER OR DEFENSIVENESS; EITHER OF WHICH ARE DISTRACTIONS. A LITTLE PROFESSIONAL COURTESY GOES A LONG WAY. SO DOES THE LACK OF IT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: NO RESPONSE FROM COMPANY ABOUT EVENT.
