Narrative:
On takeoff from sna, at 854 ft MSL, VNAV was selected. The airspeed bug slewed to 157 KIAS as it should. However, the autothrottles came back to 1.02% EPR (not enough power for climb, on a noise abatement SID). Immediately I manually pushed power levers forward and engaged flight crewh and reselected VNAV. It then operated normally. A company as soon as possible report was filed in the event a noise violation was an issue. I don't think it was.
Original NASA ASRS Text
Title: A B752 CAPT RPTED THAT HE MAY HAVE VIOLATED THE NOISE ABATEMENT PROC DURING DEP FROM SNA.
Narrative: ON TKOF FROM SNA, AT 854 FT MSL, VNAV WAS SELECTED. THE AIRSPD BUG SLEWED TO 157 KIAS AS IT SHOULD. HOWEVER, THE AUTOTHROTTLES CAME BACK TO 1.02% EPR (NOT ENOUGH PWR FOR CLB, ON A NOISE ABATEMENT SID). IMMEDIATELY I MANUALLY PUSHED PWR LEVERS FORWARD AND ENGAGED FLT CREWH AND RESELECTED VNAV. IT THEN OPERATED NORMALLY. A COMPANY ASAP RPT WAS FILED IN THE EVENT A NOISE VIOLATION WAS AN ISSUE. I DON'T THINK IT WAS.
