Aircraft are the latest and greatest symbol of the
machine age. On page 37 of the Transportation (October 1997)
issue of Scientific American is a graph of projected per capita traffic
volume as a function of average national income. The graph shows
that as income rises, so does distance travelled. The graph is
part of an article by A.Schafer & D. Victor on "Global Mobility"
and forecasts that high speed transport will account for 25% of
passenger miles in 2020, up from 9% in 1990. High speed transport
is aircraft or very fast train.
In Sydney Australia there is furore about aircraft
noise. Sydney airport is within five kilometers of the city
center, and aircraft movements are over densely populated areas.
The federal government (which controls airports) has just rescheduled
air traffic that previously annoyed the seagulls of Botany Bay and sent
it over the most densely settled part of Sydney. (The Kings Cross -
Woollahra section). The "No Airports" political party fails to
see the necessity of airports in Sydney Basin. (I think I am
beginning to agree with them). The inhabitants of Badgery's Creek
in Western Sydney (where the government proposes to open a second
airport) do not want an airport either.
Below are catalogued the disadvantages of airports
in cities, and reasons for concentrating airports in remote locations.
FACTS ABOUT AEROPLANES.
- Aeroplanes spread disease. The first
defence against the expected pandemics of the third millenium will be
restrictions on rapid international travel. Placing international
airports in remote areas would simplify any quarantine procedures found
- Aircraft are beginning to regularly fly into the
ground near airports. It does not seem like a very good idea to
have densely populated areas near airports.
- Airports are unwelcome additions in any
city. They are noisy and smelly. An Australian federal
government that promised to move all commercial airports out of the
Sydney basin might well earn itself an extra handful of seats in the
Representatives & an extra seat in the Senate. Melbourne
people might well feel the same way.
- International tourism would be only marginally
affected if airports were relocated to remote areas. One
international airport for South-eastern Australia near Condobolin NSW
should suffice. Condobolin is about equidistant from Sydney,
Melbourne and Brisbane and Adelaide, and is sparsely settled.
Very fast (250 MPH) trains could deliver passengers within two or three
hours to the major cities. Sightseeing tourists could start their
holiday in "outback" Australia.
- Aeroplanes produce massive pollution and consume
enormous amounts of energy. I have not calculated exact figures,
but aeroplanes appear to consume about half as much energy as is used
to provide the total electricity budget for Australia.
DEDUCTIONS FROM THE FACTS.
- An aeroplane engine (RB211)
powers up to about 30 megawatts.
- Per capita Australian consumption of electricity
kWh p/a (for 1995) which is (divide by 365.25 & then divide by 24)
about 950 watts per person averaged continuously.
- Maximum electricity generating capacity in
Australia (1994) was 38,830,000
- Sydney has a population of about 3,750,000
and Australia has about 18,500,000.(1997)
- According to the Australian
Bureau of Statistics on domestic airlines aircraft movements in
Australia there are more than 500,000 aircraft movements and more than
450,000 hours are flown per annum.
- A four engined jetliner operating continuously
could produce 120 MW which is as much power as would be used by 130,000
- Twenty-nine four engined aeroplanes operating
continuously could produce sufficient electricity to power Sydney.
- Three-hundred-twenty-four (324) four engined
aeroplanes could supply the maximum power load for Australia.
- One hundred and fifty four (154) four engined
aeroplanes could produce enough energy (averaged) to power Australia.
- Australia has fifty one domestic airlines
aeroplanes in the air continuously (averaged 24 hour basis).
Suggested solution? Use suitable tax breaks, and
initiate a Very Fast Train project linking Melbourne, Adelaide,
Brisbane & Sydney to an International airport in Central NSW.
Turn existing city airports into parks. Australia could probably
manage with two international airports, one about central NSW (near
Condobolin), the other at a suitable distance from Perth.
Intranational flights should be limited to between towns with small
- I have used the maximum power figure (30MW) of
the RB211. However since flights average 54 minutes I believe
that this is not too unreasonable.
- Overseas aircraft movements were not included.
- Regional aircraft movements were not included.
- Aircraft probably produce more pollution per
output joule than coal fired power stations.
- Consequently the "deductions" could have errors,
but are I believe within an order of magnitude of the actuality.
I would appreciate it if anyone who found errors or disagrees with my
assumptions reported them to me.
- Much of the data is from the CIA. The CIA
seems to be moving & changing it's html pages. This
does make the task of keeping up-to-date linksI attempt to
