Not a US pilot so can't really help you here. The full text reads:
NOISE ABATEMENT PROCEDURE (TURBOJETS):
Excess of 75000lbs, Airport Operator requests
the use of "Close-in" departure procedures in
accordance with FAA Advisory Circular 91-53A,
Noise Abatement Departure Profile.
So you need to get your hands on the Circular... Probably something like straight ahead to 3,000ft AAL
before level acceleration, 1,500ft for Climb thrust... or something...!
I used to love the smell of Jet-A in the morning...
