Noise abatement procedures, curfews, and violations

Over the weekend, I received a “Notice of Violation” for one of our club 11156312_641478039285575_8823997895904999176_naircraft from the City of Santa Monica. It reminded me that we need to continue to (re-)educate pilots on the topics of noise, noise abatement procedures, curfews, and other related topics that are very important when flying in the LA Basin and many other areas.

Almost every airport that is located in an urban area or has housing near the airport is likely to have some sort of noise abatement procedure and/or some sort of flight operation curfew or restriction. The degree to which these restrictions and procedures are enforced seems to be directly related to the cost of the real estate nearby.

It’s not always easy to find out the details of noise abatement procedures before you go to an airport. In some cases, all you get is “Noise abatement procedures in effect, ctc arpt manager for details.” (this is the verbatim text from the AFD/Chart Supplement/AirNav for our home airport, EMT). Even a google for “EMT Noise Abatement Procedure” doesn’t immediately get you a good link. A little digging eventually finds me the LA County web site with some information. At EMT (San Gabriel Valley Airport, formerly El Monte Airport), I wouldn’t say that pilots are conscientious about adhering to the noise abatement procedure and I rarely hear any complaints or admonitions from the tower nor have I heard of any repercussions to pilots who fail to heed the procedure. There is no sign at EMT to alert pilots to the noise abatement procedures (there’s a poster in the pilots lounge), but there is a sign that advises no pattern practice between 8PM and 8AM [I’ll also note that the County web site lists different times for no pattern practice than is noted on the sign at the airport]. So, some pilots may erroneously think noise isn’t a big deal from their experience at EMT.

At other airports, the procedures may be much more stringently enforced. All of the airports that are closer to the coast in LA (SMO, HHR, TOA, LGB, and SNA) have much more stringent noise enforcement. Santa Monica is a good example. If you look at the airport remarks, you’ll see that they document a number of noise restrictions and cautions (I’ve shortened the list to remove some that are not applicable to small piston aircraft):

- no touch/go, stop/go, or low apch permitted on sat, sun, hols; weekdays ss-0700.
- vfr deps ry 21 turn left 10 degrees at end of ry then turn right 225 deg to over-fly golf course w of arpt. no crosswind turn until reaching lincoln blvd (1 mile w) and out 800 ft msl

-noise lmts all acft: pure jet and stage ii (with/without hushkits) prohibited. max moise limit 95.0 dba sngl event noise exposure level (senel) rcrdd 1500 ft extdd cntrln.
- curfew: no eng starts, apu, or tkofs exc ppr lifeguard flts 2300-0700 mon-fri and 2300-0800 wkends.
- noise readings on 122.85 nml ofc hrs.
- hel flt trng opn prohibited; hel opns apch arpt bdry at midfield at or above 900 ft msl.
- ry 03/21 dep end approx 220 ft fm residential homes. extended high power settings on run-up or dep negatively impact the community.

I’ve highlighted the particular one for which we received a violation. This violation was a warning, but a repeat could result in fines and possible actions against a pilot, so they must be taken seriously. Santa Monica does document a lot of these with a variety of signs at the airport too.

In general, violations are sent to the registered owner of an aircraft. This can sometimes take weeks or months.

AACIT asks that all pilots become familiar with the noise abatement procedures at the airports where they operate and comply with all procedures, as long as that can be done in a safe manner; curfews should be strictly adhered to. If you have questions about procedures, ask a tower controller or ask your CFI or a board member.
