Monthly Noise Report – February 2016 Page 2
I. Introduction This report has been prepared in an effort to inform the Airport Commission and the public regarding the Santa Monica Airport’s Noise Management Program. The report provides details on aircraft operations, noise violations, airplane and helicopter deviations, and curfew departures for the month of February 2016. II. Aircraft Operations Data The total number of aircraft operations (aircraft operation is defined as one takeoff or one landing) recorded during the month of February 2016 was 7,568; which represents a 22% increase from the 6,191 operations recorded during February 2015. Approximately 28% of the operations were instrument flights (IFR transient), 24% were local flights (VFR local operations), and 49% itinerant flights (VFR transient). The total traffic count is recorded by the FAA control tower. See attachment A for the Airport Traffic Record.
Following are breakdowns of the total operations grouped by aircraft type along with a graph for each type indicating each monthly aircraft operations trend during the preceding 12 month period.
Propeller Aircraft Operations There were approximately 5,803 propeller aircraft operations, comprising approximately 77% of the total operations. Propeller aircraft operations for February 2016 increased 27% from the 4,556 propeller aircraft operations recorded during February 2015.

Helicopter Operations Of the monthly aircraft operations for February 2016, there were approximately 232 helicopter operations, comprising approximately 3% of the total operations. Helicopter operations for February 2016 decreased 28% from the 320 helicopter operations recorded in February 2015.
Jet Aircraft Operations Of the monthly aircraft operations for February 2016, there were approximately 1,533 jet aircraft operations, comprising approximately 20% of the total operations. Jet aircraft operations for February 2016 increased 17% from the 1,315 jet aircraft operations recorded during February 2015.
Daily jet operations vary significantly from day to day. Jet operations for the month of February 2016 averaged 51 per day. The line graph below represents the daily operations for jet driven aircraft for the month of February 2016.
III. Voluntary Arrival Curfew During the month of February 2016, Airport Staff logged a total of 21 aircraft arrivals during the Voluntary Arrival Curfew (VAC) (11:00 p.m. to 7:00 a.m. weekdays, 11:00 p.m. to 8:00 a.m. weekends/holidays). The graph below depicts the number of arrivals for each VAC hour during the month of February 2016. For a listing of aircraft arrivals during the night hours, see attachment B.
IV. Deviations from Recommended VFR Noise Management Procedures Santa Monica Airport requests that arriving and departing VFR aircraft follow certain flight paths for Noise Management. Aircraft that are observed to be operating outside of the requested flight paths are contacted and counseled of the proper Noise Management procedures. During the month of February 2016 airport staff spent several hours observing aircraft adherence to the requested noise management procedures. Staff contacted those aircraft operators observed to be deviating from established VFR procedures, requesting compliance with the Airport’s Recommended Noise Management Procedures. For a breakdown of the deviations investigated see attachment C.
V. Noise Management Briefings Most aircraft are capable of meeting the 95.0 dBA maximum SENEL limit with changes in pilot technique or aircraft operating weight. The goal of the Santa Monica Airport’s Noise Management Program is to communicate methods or techniques, which will lower aircraft noise levels, which in turn will minimize the impact of aircraft operations to the surrounding community.
VI. Authorized Departures & Curfew Violations The night departure curfew prohibits takeoffs or engine start-ups between 11 p.m. and 7 a.m. Monday through Friday, or until 8 a.m. on weekends and holidays. Exceptions are allowed for bona fide medical or public safety emergencies. During the month of February 2016, there were no authorized curfew departures or curfew violations. See Attachment D. VII. Noise Violations
Santa Monica Airport enforces a maximum noise limit as approved by City Ordinance adopted in 1985. The Santa Monica Municipal Code section 10.04.04.060 states that “No aircraft shall exceed a Single Event Noise Exposure Level (SENEL) of 95.0 dBA as measured at the Airport Noise Measuring Stations existing on February 1, 1985.” The only Remote Monitoring Stations (RMS) that can be used for the enforcement of the 95.0 dBA SENEL are RMS 1 and RMS 2. These monitors are located 1,500 feet from each end of the runway. (See Attachment F for the location of RMS 1 & RMS 2 and Attachment G for the definition of SENEL).
A violation occurs when an aircraft exceeds 95.0 dBA Single Event Noise Exposure Level. During the month of February 2016, there were 15 noise violations, a decrease of 29% from the 21 noise violations recorded during February 2015. A summary of noise violations for February 2016 are listed on attachment E.

The noise violations listed in the graph below were registered at RMS sites 1 or 2 and do not include exempt medical emergency operations. VIII. AIRCRAFT RELATED COMPLAINTS
During February of 2016, Airport Noise Management staff received a total of 93 inquiries from 30 different residences. These inquiries were investigated and proper actions were taken in accordance with the Airport’s “Fly Neighborly Program” and the City of Santa Monica’s “Noise Code”.

(Single Event Noise Exposure Level)
Definition of Single Event Noise Exposure Level (SENEL)
As a result of an agreement between the City of Santa Monica and the FAA, an Airport Ordinance was established setting a maximum noise level of 95.0 dBA Single Event Noise Exposure Level (SENEL) measured at noise monitor sites 1,500 feet from each end of the runway.
As an aircraft approaches each noise monitor, the sound of the aircraft begins to rise above the threshold level. The closer the aircraft gets, the louder it is until the aircraft is at its closest point directly overhead. As the aircraft passes, the noise level decreases until the sound settles below the threshold level. Such a history of a flyover is plotted in the graph below. The highest noise level reached during the flyover is called the “Maximum Noise Level”, or LMax. Referring to the same graph, the area within 10 dB of the LMax is the area from which the SENEL is computed. This metric takes into account the maximum noise level and the duration of the event. The SENEL value is always higher than the LMax value for aircraft events.
A-WEIGHTED SOUND LEVEL (dBA) – The sound pressure level in decibels as measured on a sound level meter using the A-Weighted filter network. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the response of the human ear. It is a numerical method of rating human judgment of loudness.
