• Began to really crop up in the 1970’s when
the FAA began classifying certain G.A.
airports as “reliever” airports
– Gave Birth to many community action groups
out of fear
– Reliever airports in Indianapolis are- Metro, Mt.
Comfort, Executive, Eagle Creek, and
Greenwood.
Airports Need Good Community Relations

• The inherent conflict with many airports is
that they need (and the populations wants
them) to be near populated areas to survive
and grow but these same areas don’t want
airport noise
• We cannot afford to simply say “tough, the
airport was here first.” Most always the
community is more powerful than the
airport.
Dealing with the noise problem has typically
involved a 2 fold strategy:

• 1. Noise abatement- Reducing the noise
footprint.
• 2. Community relations- winning the
public.
Noise Abatement

Help
• 1. Source Control- quieter aircraft as
designed by engineers- ie. Mixers for
turbojets, longer props for recips.
• b. Operating Controls– Changing traffic patterns- temp. or permanent
– Preferred departure paths
– Power restrictions- Cruise prop. configuration
– Crossing restrictions
Noise Abatement ctn.

• Land use controls- a proactive approach usually
taken by the airport board to limit the # of noise
sensitive activities near the airport:
Next
• Zoning restrictions
Help
• Building codes- requiring soundproofing
• Purchase development rights to nearby land
– Could involve soundproofing houses/buildings and
reselling them
• Purchasing “Aviation Easements” to titles
Noise Approach #2- Community Relations:

Help
• In addition to noise abatement activities there is
the community relations approach to noise
involving- “Selling the virtues of the Airport”
• 2 approaches
– Statistical- revenue, tax, salary figures
– Qualitative Approach- P.R. campaign
• Profile airport related businesses on TV. Fly a
reporter etc.
• Newspaper articles
• Also helps to get involved with certain community
related organizations Ie. Rotary Club, Lions Club,
etc.
FAR 36- Noise Limitations

•
The Airport Noise and Capacity Act of 1990 limits the options
available to the airport proprietor to govern the types of aircraft
operating from an airport. Most airports have virtually no ability to
limit the types of aircraft operating from the airport as long as these
aircraft comply with federal guidelines regarding noise emissions.
Stage I – early jets- extremely loud
Stage II – around 100 db- older 727’s 737’s
Stage III- New jets- i.e. 777, 757 and retrofitted older jets such as
727 with hush kit. Avg. 90 db- (10 quieter than stage II).
Incorporate the latest noise reduction technology.
* All Stage I and Stage II aircraft over 75,000 lbs. are prohibited from
flight within the continental U. S. This prohibition does not apply to
Stage II aircraft weighing less than 75,000 lbs.

• Discussions are currently beginning which
may lead to a new Stage IV classification.
This new classification would sub-divide the
Stage III classification. The quietest of the
current Stage III fleet would be reclassified
as Stage IV and the loudest of the current
Stage III aircraft would remain as Stage III.
The reclassified Stage III aircraft would
eventually be phased out of operation.

• *You are the manager of an FBO whose major
income is from subcontract freight operations that
are the most active from dusk to dawn (night).
You are present at the local airport board meeting
and are preparing to issue your response to the
opponent group’s demands that you pursue a
business model that can be carried out during the
day. They want to limit operations at the airport
from 10 p.m. until 7 a.m. to emergency use only.
Using whatever fictional facts & figures you
want, you are to convince this group of the
importance of your FBO to the community.
Prepare your response. (1 pg.) (See next pg.
