Narrative:

On takeoff from oak, while on the coast 5 departure, we had an altitude deviation of 400 ft. There is a crossing restr of at or below 2000 ft at 4 DME. This is for departing traffic out of sfo. On takeoff, we had a bird strike which was being reported to ATC. Company policy requires us to use maximum thrust on sunday mornings. The B757 FMS limits g-loads to .5, this is for passenger comfort. Due to the light weight and rapid climb rate, the .5 g-load seems to have played a part in the altitude deviation. Modern aircraft cockpits have come a long way in reducing pilot workload and allowing them to focus attention outside more. This is especially important with the high density of traffic that we are seeing more and more of. We must be extra vigilant not to allow ourselves to forget what we were taught as student pilots, always fly the airplane first. As it turns out, no conflict existed. When we switched to norcal departure, they cleared us immediately to 10000 ft, but reminded us of the 2000 ft constraint.

Title: B757 DEP FROM OAK OVERSHOOTS ALT XING RESTR.

Narrative: ON TKOF FROM OAK, WHILE ON THE COAST 5 DEP, WE HAD AN ALTDEV OF 400 FT. THERE IS A XING RESTR OF AT OR BELOW 2000 FT AT 4 DME. THIS IS FOR DEPARTING TFC OUT OF SFO. ON TKOF, WE HAD A BIRD STRIKE WHICH WAS BEING RPTED TO ATC. COMPANY POLICY REQUIRES US TO USE MAX THRUST ON SUNDAY MORNINGS. THE B757 FMS LIMITS G-LOADS TO .5, THIS IS FOR PAX COMFORT. DUE TO THE LIGHT WT AND RAPID CLB RATE, THE .5 G-LOAD SEEMS TO HAVE PLAYED A PART IN THE ALTDEV. MODERN ACFT COCKPITS HAVE COME A LONG WAY IN REDUCING PLT WORKLOAD AND ALLOWING THEM TO FOCUS ATTN OUTSIDE MORE. THIS IS ESPECIALLY IMPORTANT WITH THE HIGH DENSITY OF TFC THAT WE ARE SEEING MORE AND MORE OF. WE MUST BE EXTRA VIGILANT NOT TO ALLOW OURSELVES TO FORGET WHAT WE WERE TAUGHT AS STUDENT PLTS, ALWAYS FLY THE AIRPLANE FIRST. AS IT TURNS OUT, NO CONFLICT EXISTED. WHEN WE SWITCHED TO NORCAL DEP, THEY CLRED US IMMEDIATELY TO 10000 FT, BUT REMINDED US OF THE 2000 FT CONSTRAINT.
