Narrative:
On departure out of dtw on metropolitan 8 SID we passed through 10000' and began our normal acceleration in the climb from 250-300 KTS. After climbing another 1000-3000' departure cleared us for normal speed. I said we did not know we were being restr. They said it was on the SID. Rechking the SID we found, 'maintain 250 KTS until advised' stuck under special instructions, after such astounding information contained in this paragraph as 'transponder codes will be assigned by ATC' (what a deviation from SOP), and the lines and frequencys on the chart were from departure. These are nice to know, but the 250 KT restriction should be in the takeoff procedures so it will not be missed by 2 conscientious pilots. Also controllers (as they do in bos) should remind pilots of the restriction, especially if the restriction is going to be maintained above 10000' MSL, and thus require a change of normal cockpit procedure (i.e., to accelerate to normal climb schedule airspeed).
Original NASA ASRS Text
Title: FLT CREW OF MLT UNAWARE OF NEW SPEED RESTRICTION DEPARTING DTW ACCELERATED AT 10000'. CTLR INTERVENED.
Narrative: ON DEP OUT OF DTW ON METRO 8 SID WE PASSED THROUGH 10000' AND BEGAN OUR NORMAL ACCELERATION IN THE CLB FROM 250-300 KTS. AFTER CLBING ANOTHER 1000-3000' DEP CLRED US FOR NORMAL SPD. I SAID WE DID NOT KNOW WE WERE BEING RESTR. THEY SAID IT WAS ON THE SID. RECHKING THE SID WE FOUND, 'MAINTAIN 250 KTS UNTIL ADVISED' STUCK UNDER SPECIAL INSTRUCTIONS, AFTER SUCH ASTOUNDING INFO CONTAINED IN THIS PARAGRAPH AS 'XPONDER CODES WILL BE ASSIGNED BY ATC' (WHAT A DEVIATION FROM SOP), AND THE LINES AND FREQS ON THE CHART WERE FROM DEP. THESE ARE NICE TO KNOW, BUT THE 250 KT RESTRICTION SHOULD BE IN THE TKOF PROCS SO IT WILL NOT BE MISSED BY 2 CONSCIENTIOUS PLTS. ALSO CTLRS (AS THEY DO IN BOS) SHOULD REMIND PLTS OF THE RESTRICTION, ESPECIALLY IF THE RESTRICTION IS GOING TO BE MAINTAINED ABOVE 10000' MSL, AND THUS REQUIRE A CHANGE OF NORMAL COCKPIT PROC (I.E., TO ACCELERATE TO NORMAL CLB SCHEDULE AIRSPD).
