Narrative:

Prior to takeoff with an EFIS aircraft we always get the command bars to takeoff and go around, heading, and altitude select. Somewhere during taxi out the go around mode became deselected. During the takeoff and initial climb I discovered that the go around mode was not selected and selected it. This however caused the heading select mode to become disconnected. The command bars disappeared just about the time I was starting a right turn to a heading of 110 degrees magnetic. The flaps were being retracted to 10 degrees and pitch was changing. I reduced the bank of aircraft to between 10 degrees and 15 degrees got heading mode back and selected 110 degree heading. With a strong southwest wind we exceeded our 4 mi limit to make our turn. We got to 4.9 mi from midway airport. We departed on runway 31C. We did not break any altitudes. In retrospect -- I should have verified the go around mode on line up and with the low ceiling, had the copilot make the initial heading selection. Supplemental information from acn 361443: after takeoff at 1300 ft I told the captain to turn to 90 degree heading. The captain was slow to respond I thought he was waiting to gain more speed before he made the turn but when we had sufficient speed he still was not turning at a fast enough rate. The controller told us we were 2 NM north of the 4 mi restr, our DME read 4.9 NM. The controller told us if we can't meet the restr of the SID we must notify them. The captain could not explain why he was so slow in making the turn. I did not take control of the aircraft because the aircraft was under control and other than reminding the captain to turn I did not think there was much more I could have done. I guess I could have reminded him of the DME restr on the turn. I will if this should happen again. Also mdw is our home base which could have caused complacency.

Title: SLOW RATE OF TURN BY DEP TFC, A CORPORATE JET OUT OF MDW, EXCEEDS THE DME LIMIT ON THE SID DEP PROC.

Narrative: PRIOR TO TKOF WITH AN EFIS ACFT WE ALWAYS GET THE COMMAND BARS TO TKOF AND GAR, HEADING, AND ALT SELECT. SOMEWHERE DURING TAXI OUT THE GAR MODE BECAME DESELECTED. DURING THE TKOF AND INITIAL CLB I DISCOVERED THAT THE GAR MODE WAS NOT SELECTED AND SELECTED IT. THIS HOWEVER CAUSED THE HEADING SELECT MODE TO BECOME DISCONNECTED. THE COMMAND BARS DISAPPEARED JUST ABOUT THE TIME I WAS STARTING A R TURN TO A HDG OF 110 DEGS MAGNETIC. THE FLAPS WERE BEING RETRACTED TO 10 DEGS AND PITCH WAS CHANGING. I REDUCED THE BANK OF ACFT TO BTWN 10 DEGS AND 15 DEGS GOT HEADING MODE BACK AND SELECTED 110 DEG HDG. WITH A STRONG SW WIND WE EXCEEDED OUR 4 MI LIMIT TO MAKE OUR TURN. WE GOT TO 4.9 MI FROM MIDWAY ARPT. WE DEPARTED ON RWY 31C. WE DID NOT BREAK ANY ALTS. IN RETROSPECT -- I SHOULD HAVE VERIFIED THE GAR MODE ON LINE UP AND WITH THE LOW CEILING, HAD THE COPLT MAKE THE INITIAL HEADING SELECTION. SUPPLEMENTAL INFO FROM ACN 361443: AFTER TKOF AT 1300 FT I TOLD THE CAPT TO TURN TO 90 DEG HDG. THE CAPT WAS SLOW TO RESPOND I THOUGHT HE WAS WAITING TO GAIN MORE SPD BEFORE HE MADE THE TURN BUT WHEN WE HAD SUFFICIENT SPD HE STILL WAS NOT TURNING AT A FAST ENOUGH RATE. THE CTLR TOLD US WE WERE 2 NM N OF THE 4 MI RESTR, OUR DME READ 4.9 NM. THE CTLR TOLD US IF WE CAN'T MEET THE RESTR OF THE SID WE MUST NOTIFY THEM. THE CAPT COULD NOT EXPLAIN WHY HE WAS SO SLOW IN MAKING THE TURN. I DID NOT TAKE CTL OF THE ACFT BECAUSE THE ACFT WAS UNDER CTL AND OTHER THAN REMINDING THE CAPT TO TURN I DID NOT THINK THERE WAS MUCH MORE I COULD HAVE DONE. I GUESS I COULD HAVE REMINDED HIM OF THE DME RESTR ON THE TURN. I WILL IF THIS SHOULD HAPPEN AGAIN. ALSO MDW IS OUR HOME BASE WHICH COULD HAVE CAUSED COMPLACENCY.
