Hello,

As I can´t find anything in my Jeppesen(neither on the 10-4 pages, nor the USA part) I was wondering about the US Noise Abatement Proc. for ICAO Annex 16, Chapter 3(e.g.737NG) airplanes.

-What is the regular T/O procedure in the USA with regards to thrust
reduction altitude and acceleration altitude?

-Are the regional procedures or specific airport procedures?

-Where can I find some regulatory pages about it?


Many thanks and brgds.

There are no noise abatement profiles per say in the USA. In Canada and I believe Europe too noise abatement profiles are based on the ICAO A and B profiles.

In the US unless specified on a noise abatement plate you are expected to fly a standard departure profile which for a Boeing product is V2+15-25 to 1000 feet, accelerate, retract flaps, set climb thrust, climb to 3000 feet at VM, then acelerate to enroute climb speed. It is basically a VNAP B with the flap retraction and thrust reduction reversed.

Hope that helps.

Here is a link to the Canadian version of the ICAO departure profiles.

This is an advisory circular from the FAA. Hope this answsers your question.

============================================================ ===========

However, some airport authorites incorporate the advisory circular into their specific departure procedures to avoid noise sensitive areas.


Here is a sample publication from Oakland Airport.

And also from Naples Florida

Mr. Sobchak. US airports, except for some in the mountains, for us are either "close-in" noise abatement or "distant".

A few places such as White Plains, NY (HPN) and maybe Palm Beach (PBI)have close-in: at 1,000' we go to "cut-back" EPR, climb to 3,000' then after flap/slat retraction, climb EPR.

At most airports, after slat/flaps retracted at 1,000' we set quiet EPR, climb at Vzf and at 3,000' use climb EPR.


In DTW (must make 5,000 by 10 miles) we go straight to climb EPR after Vzf, and keep Vzf until 5,000'. You must also watch O'Hare (ORD). Two different climb restrictions exist: either be at 4,000' by 8 DME or 3,000' by 5 miles. If in doubt, use climb EPR to make a restriction.

There's no requirement for Noise Abatement Procedures in the US.

No one will hear your aircraft over the sound of their own voice!

The AC talks about ¨Noise Sensitive Airports¨ with regards to the acceleration altitude (min 800ft AGL) for turbojet/turbofan aircraft. Where can one find the official list of Noise Sensitive Airports??? As far as I´m concerned, every airport is potentially noise sensitive, but I need to find the official list. Could anyone help with a link to the actual list?
Thanks,

Thats a negatory good body. Many airports in the US have published procedures. John Wayne Airport in California has a special noise abatement departure procedure. Airlines include this procedure in their FCOM for various airport.

I have never seen such a list, but it does not mean it wouldn't exist.
Usually, when I am at a certain airport and I am not sure whether or not it is noise-sensitive, I have a look at the Jepp Text, ATC section, find the airport in question and voilà ... I find the details about ICAO/FAA differences, noise abatement, holdings, etc.
