SECTIO~ 5. Sectlon lOlllC of sald chapter is hereby
amended to read as follows:
SECTION 10111. Touch and Go Landlngs. Touch and go
landlngs shall be permitted only after the pilot of the alrcraft
has recelved approval from the air t=afflC controller in the control
tower and in no event shall be made unless the alrcraft has landed
prlor to reachlng the touch and go llmlt line palnted on the runway
In use. No touch and go landings shall be made durlng the hours
of darkness or by hlgh performance a1rcraft6
SECTION lOlllA. Approach. No pilot shall made a short
approach or a straight-in approach to the a1rport unless approval
1S obtalned from the control tower prlor to start1ng ~~e approach.
SECTION lOllIB. Sinulated Forced Land1ngs. There shall
be no simulated forced land1ngs within the confines of the traf~lc
pattern.
SECTION IOllIC. Touch-and-Go, Stop-and-Go and Low
Approach Operation. Except (l) ln the case of an emergency, (il)
where necessitated by safety cons1derat1ons, or (lli) when requlred
by the Federal AV1at1on Adminlstration, no person shall operate

2. the nOlses may not reach peak levels hlgh enough to be
above the threshold of annoyance; and
3. the nOlses may be non-regularly recurring and even be
wanted sounds rather than nOlse. In any eve~t, the presence of
other sounds or noises ln an environment that contalns aircraft
nOlse cannot be expected to reduce the adverse effects, if any,
of the alrcraft nOlse on people.

It is found that a limit of 90 SENEL at the Santa Monlca
NOlse Monitoring Statlons will provlde some modest reductlons
In the aircraft nOlse enVlronment at Santa Monica, and lS con-
sistent with nOlse llrnits prescribed by FAA for the certification
of small aircraft 11censed to operate in the Unlted States.
A llmlt of 87 SENEL at the Noise Moultor Stations will
provlde a signlflcant reauctlon in the alrcraft nOlse environment
at Santa Monica and is conslstent wlth reco~nendations for
environmental nOlse in residental areas and also with technology
of build~ng qUleter a~rcraft. A few of the new small jet aircraft
wlIl be able to meet either an 87 or 90 SENEL limlt.

It is presurr:.ed 1.n the calculation of CilELs ~li th
the SENEL l~~its set at 87 and 90, that the reduction
in operat1.ons that could ensue is only apparent, and
that the level o~ operat1.ons would remain the same
because newer, quieter aircraft, including Jets, would
replace those a1.rcraft operations now ~n excess of 87
or 90 SE:mL.
However, there would be an effective (more or less)
long lasting reduction 1.n 7% of the operat~ons all for
aircraft at SE~mLs higher than 85, and about a 20%
reduction in the oDerations of aircraft at SENELs higher
than 80, were the SEllEL limit set at 85 and BO respectively.
Accordingly, t~e CNELs for the cond~t1.ons of an SE~mL
limit of 85 and for a l1.mit of 80 SE~mL are calculated on
the assumpt1.on that the nur.ber of operat1.ons, l.n the
.
.
highest SE~SL ranges, would be reduced by 30 with a limit
of 85 SENEL and 62 with a limit of 80 SENEL.
