A320 Thr reduction/Acc alt

Hi Guys,

Ive recently started working for an A320 operator. The company requires us in the departure profile to have a thr reduction alt of 1000aal and acc alt of 3000aal.

With my previous company both were 1000aal and so im still getting used to the differences within the climb profile.

A few days ago, I was on the SID which had a published stop alt of 6000. Passing about 2000agl, we were cleared direct to FL80.
Consequently I set 8000, but due to alt constraint I then pulled open climb.
This consequently took us from SRS direct to open climb at 1000 lower than as per the profile.

What do you suggest I do as an alternative? I could remove the constraint in the SID or select V/S?
Perhaps in a busy TMA VS would be appropriate but what about in a more isolated airfield??

How significant is accelerating at 3000 agl as opposed to accelerating earlier? Am I perhaps putting too much thought into this or is it not that significant?
My understanding is this is just a noise abatement procedure?

Thanks

SI.
