ALTDEV -- SID.

Narrative

THE ALTDEV TOOK PLACE AS PART OF THE SID FOR RWY 28 AT MILLVILLE; NJ (MIV). THE SID CALLED FOR AN INITIAL ALT OF 2500 FT BUT WE MISTAKENLY UNDERSTOOD 4000 FT AND PUT 4000 FT IN THE ALT ALERTER. THE EVENTS THAT FOLLOWED UP TO THE DEV WERE AS FOLLOWS: AFTER MY FO PICKED UP THE CLRNC HE BRIEFED ME ON IT BUT DID NOT MENTION THE SID. I CONFIRMED WITH HIM THAT WE WOULD BE MAKING A L TURN DIRECT TO LEEAH INTXN; HE AGREED. JUST PRIOR TO TAKING THE RWY I REALIZED HE HADN'T PUT OUR INITIAL ALT IN THE ALERTER. I ASKED HIM WHAT IT WAS AND HE SAID 4000 FT; SO I SET 4000 FT IN THE ALERTER AND HE CONFIRMED THE ALERTER SETTING. I THEN NOTICED ON HIS CLRNC THAT HE HAD WRITTEN 'L2.' I ASKED WHAT THAT WAS AND HE SAID A SID. I SCRAMBLED TO LOOK AT THE SID FOR WE WERE APCHING OUR CLRNC VOID-TIME. I GOT THE 400 FT; THEN RIGHT TURN TO 40 DEGS TO INTERCEPT SIE R-333; SO WE DEPARTED. CLBING OUT OF 3000 FT ATLANTIC CITY APCH INFORMED US WE WERE SUPPOSED TO BE AT 2500 FT; BUT SAID TO GO AHEAD AND CLB TO 4000 FT. IN TALKING WITH THE FO AFTERWARDS HE SAID HE HAD LOOKED AT THE SID BUT FAILED TO NOTICE THE 2500 FT IN THE 'THENCE' SECTION. HE ASSUMES HE GOT THE 4000 FT ALT FROM GLANCING DOWN AT THE SID AND CONFUSING THE 400 FT AND 40 DEG FOR A 4000 FT ALT. THIS SIT COULD HAVE BEEN AVOIDED IF I WOULD HAVE STOPPED THE ERROR CHAIN IN SETTING UP THE DEP. I SHOULD HAVE ASKED FOR ANOTHER VOID TIME AND USED THE ADDITIONAL TIME TO FOLLOW PROPER COCKPIT RESOURCE MGMNT PROCS AND TO HELP MY FO GET 'CAUGHT UP.' SUPPLEMENTAL INFO FROM ACN 294701: ONCE WE HAD STARTED THE ENGS I GOT OUR CLRNC AND VOID TIME; WE WERE USING THE SPEAKERS SO IT WAS HEARD BY BOTH OF US. I COPIED IT DOWN. I CALLED OUT THE CHKLIST AND HANDLED THE RADIO AND THE CAPT TAXIED APPROX 1/3 THE WAY TO THE RWY THE CAPT DECIDED THAT I SHOULD FLY THIS LEG AND I HANDED HIM THE CLRNC AND THE DEP PLATE. HE REQUIRED THAT; I RUN THE CHKLIST WHILE HE CHKED THE DEP. WE WERE DISTRACTED BY A HELI MANEUVERING ON THE TXWY IN FRONT OF US. AT THIS POINT HE CHANGED THE NAV SET UP; BUT I PRESUMED IT WAS DUE TO THE CHANGE IN OUR CLRNC BY ATC (SMYRNA TRANS DROPPED) WE ARRIVED AT THE HOLD WITH 5 MINS LEFT ON OUR VOID TIME; BUT THE CAPT WAS CONCERNED TO DEP BEFORE A GULFSTREAM DOING TOUCH AND GOES RETURNED; ON TAKING THE RWY I RECALL THE CAPT CONFIRMING 400 FT THEN RIGHT TO 040 DEGS WHICH I CONFIRMED. HE RECALLS CONFIRMING 4000 FT.
