Airspace Structure; Procedure
Departing LAX on the LADYJ RNAV departure; we encountered wake turbulence; causing my First Officer to hand fly the airplane. Approaching the crossing restriction at the LADYJ fix of a hard 8;000 feet; we were informed of crossing traffic at our 12 o'clock. As I looked outside for the traffic; I heard the altitude alerter sound; called altitude and my First Officer effectively recaptured the altitude without floating the passengers. We corrected at 8;300 feet at LADYJ. ATC advised us our altitude was high and I let them know we were correcting. The lesson learned was [to] have the First Officer use the automation for level off in those types of situations and be more vigilant in watching as hard altitudes approach.
Climbing out of LAX on the LADYJ4; we complied with all altitude restrictions until LADYJ. We exceeded the 8;000 feet altitude restriction by 300 feet. We were a little distracted by some wake turbulence from a 777; complying with the SID; and verifying our top altitude for the departure. I glanced to check my chart; came back to the PFD as we reached 8;000 feet. Immediately started to nose over; not too fast or forceful since we have passengers; but we arced to 8;300 feet before we started to descend back to 8;000 feet. It was momentary but still noticed by us and ATC.I have flown this departure before; using the AP; just to make sure to meet all the altitude restrictions. After seeing it was not a problem to meet the restrictions; I decided to hand fly the departure today. Again; no problems initially; but I should have turned the AP on sooner to make sure we complied with the hard altitude since it is a high traffic area. Next time I will turn the AP on around MLIBU to make sure we level perfectly at LADYJ.
