Noise Abatement Operating Restrictions
No fixed wing aircraft with a maximum certificated gross takeoff
weight greater than 12,500 lbs shall conduct an operation at the
airport, other than an operation necessitated by an inflight emergency,
unless that aircraft is certificated for compliance with applicable
noise emission standards established in FAR 36. For purposes of
this regulation an aircraft shall be treated as certificated for
compliance with FAR 36 if it is a fixed wing aircraft which had
flight time prior to 12/31/74, and a showing is made to the reasonable
satisfaction of the airport's executive director that its noise
level on takeoff is less than the FAR 36 noise level for aircraft
of its weight first flown subsequent to 12/31/74.
To make the showing of FAR 36 equivalence called for in the foregoing
paragraph an operator of the aircraft shall produce the following
documentation satisfactory to the executive director:
a)certificate including date of manufacture; and
b)(1)Noise emission measurement data taken during test conditions
approved by the FAA or which have been published in an FAA Advisory
Circular as the noise emission measurement or FAA estimated
noise measurement for the aircraft type in question for FAR
36 comparison purposes.
(2)if (1) is unavailable, noise emission data and calculations
which demonstrate to the executive director probable compliance
with the applicable FAR 36 noise level for takeoff at the aircraft's
certified maximum gross takeoff weight are acceptable. If this
alternative method is the basis for obtaining permission to
operate at the airport, such permission may be revoked if subsequent
measurement of its takeoff noise at the airport exceeds the
applicable FAR 36 takeoff noise level. This measurement shall
be taken at the takeoff position with wind, humidity and temperature
conditions meeting the allowable FAR FAR 36 conditions. For
the purpose of this determination, if the A-weighted sound is
measured, the EPNL is deemed to be 4 dB greater than the A-weighted
sound exposure level.
Other Aircraft Use Restrictions
No person, including an air carrier or a foreign air carrier,
shall conduct at Hanscom, an operation in commerical air passenger
service in an aircraft with seating capacity of greater than sixty
seats. |
