Narrative:

It is always a coin toss as to which departure we get out of the clt. Sometimes it is the clt 5 and others it is the hornet 1. The primary difference is that the hornet 1 specifies not to exceed 250 KTS until advised by ATC and it specified a radial to fly. On this day, we got the hornet 1 stann radial. Climbing out of 10000', the captain put the nose down and started accelerating. By the time I noticed, we were doing 290 KTS. I said something and the captain slowed back to 250 KTS. There were a couple of reasons this happened. The captain was more concerned with using the WX radar to deviate around some showers and I was doing my own 'out of 10000' checklist; i.e., checking out and off times, pressurization and cabin temperature. But I think a major contributing factor is the inconsistency in departures at clt and around the ATC system. Sometimes at clt you hit 10000' and get to accelerate and other times you don't. After a long trip with 4 or 5 takeoffs from clt, it is easy to forget the 250 KT restriction since the only mention is on the SID.

Title: ACR MLG FLT CREW EXCEEDS SPEED RESTRICTION OF HORNET 1 SID AT CLT.

Narrative: IT IS ALWAYS A COIN TOSS AS TO WHICH DEP WE GET OUT OF THE CLT. SOMETIMES IT IS THE CLT 5 AND OTHERS IT IS THE HORNET 1. THE PRIMARY DIFFERENCE IS THAT THE HORNET 1 SPECIFIES NOT TO EXCEED 250 KTS UNTIL ADVISED BY ATC AND IT SPECIFIED A RADIAL TO FLY. ON THIS DAY, WE GOT THE HORNET 1 STANN RADIAL. CLBING OUT OF 10000', THE CAPT PUT THE NOSE DOWN AND STARTED ACCELERATING. BY THE TIME I NOTICED, WE WERE DOING 290 KTS. I SAID SOMETHING AND THE CAPT SLOWED BACK TO 250 KTS. THERE WERE A COUPLE OF REASONS THIS HAPPENED. THE CAPT WAS MORE CONCERNED WITH USING THE WX RADAR TO DEVIATE AROUND SOME SHOWERS AND I WAS DOING MY OWN 'OUT OF 10000' CHKLIST; I.E., CHKING OUT AND OFF TIMES, PRESSURIZATION AND CABIN TEMP. BUT I THINK A MAJOR CONTRIBUTING FACTOR IS THE INCONSISTENCY IN DEPS AT CLT AND AROUND THE ATC SYS. SOMETIMES AT CLT YOU HIT 10000' AND GET TO ACCELERATE AND OTHER TIMES YOU DON'T. AFTER A LONG TRIP WITH 4 OR 5 TKOFS FROM CLT, IT IS EASY TO FORGET THE 250 KT RESTRICTION SINCE THE ONLY MENTION IS ON THE SID.
