Council Update on Culver City Issues

The Northerly CLIFY. From all indications, the Noise modeling the FAA performed has a significant error in regards to Culver City. CLIFY is in a different place in the official waypoint publication than it was during the noise assessment. This means the noise assessment is going to have incorrect numbers for Culver City. CLIFY is …

Change in Noise over Residences-map

Following is the second part of the proposed changes noise mapping- How noise will change in each census block in the SoCal Metroplex. I’ve already mapped the total aircraft noise map here. Firstly, the FAA did provide this disclaimer about the use of this data: “This information is provided for informational proposes only and is not intended for …

Total Aircraft noise over Population map

I’m still wading through the data the FAA team has given us. Some of my initial comments to the EA team were that we needed the noise data, waypoint coordinates and.. that it’d be nice to have the Google Earth flight track data. The feedback I got back then was that was asking too much. …

Additional 30 day extension granted

The Federal Aviation Administration (FAA) is extending the public comment period for the Draft Environmental Assessment (EA) of the Southern California Metroplex project by an additional 30 days. The comment period will now run until midnight on October 8. The latest extension allows for a full 120 days of comment on the proposed project. The …

Specific feedback on Aircraft Activity Assumptions

Below are some comments and specific feedback on the assumptions about the mix of airplanes used in modeling the noise data. Comments are specific to LAX aircraft aggregation and is also intended to be applicable as a general comment to other airports. Segmentation of Night time operations are not represented 1.) During daytime the LAX airport operates in …

Specific Comments about RNAV and the Socal Draft EA

Specific Comments about RNAV Implementation and the Socal Metroplex Draft Environmental Assessment. The central community issue with the FAA’s implementation of RNAV flight paths is they take wide dispersed flow of aircraft paths and focus them into a concentration of flights around a centerline. The modeling needs to accurately reflect the anticipated noise impacts from the proposed changes …

The Persistent CLIFY

This weekend I sat down with the newly released KML and way-point data from the FAA. The new authoritative “TARGET” way-point data allowed me to confirm my coordinates and there were no surprises there. Once I loaded up the new flight track KML on top of my authenticated flight tracks I got a bit of a surprise: …

LAX Roundtables review and comment of Metroplex Procedures

At the July meeting of the LAX / Community Noise Roundtable Boardmember Steve Alverson summarized the LAX specific changes in the draft Environmental Assessment.  He listed some of the proposed changes to arrival and departure procedures and the extent to which Roundtable noise abatement recommendations were incorporated into the proposed procedures. It’s worth viewing, particularly starting at page …

Are the Airspace changes good or bad for Culver City?

I was asked recently if the changes to the airspace are Good or Bad to Culver City. My answer, which we discussed at the last Culver City meeting about NextGen impacts, is “Yes, No, and We won’t know until its implemented”. The FAA has a summary of potential benefits for the entire airspace and Culver City’s changes …

Proposed flight path undermines LAX Noise Abatement efforts

The proposed LAX BIGBR STAR replaces the BASSET and REDEYE conventional procedures. I am concerned about the increased noise impact that lowering the altitude 12.5% over residential areas will cause. UPDATE 9/2/2016* The proposed LAX MDNYT STAR will replace REDEYE for Over Ocean Operations. It is unclear from the Final EA whether the new CLIFY …
