Jet Aircraft Noise - Ages of Problem

Noise of jet aircraft is not a new issue. In Europe, we heared a news how certain airport ban Russian aircraft because they breach the allowed limit of sound measurement. Certain western jet engine manufacturers starting to design engine with less or emitting sound that comply with European standard.
In US an already noise-conscious, busy Santa Monica airport (SMO) just north of LAX is set to adopt a city council ordinance prohibiting category C and D aircraft (those aircraft with approach speeds of 121 knots or more, but less than 166 knots) from using its sole 4,973-by-150-foot runway in spite of a letter from the FAA that calls the move "flatly illegal." With a Dec. 5 meeting set for SMO representatives and the FAA, the issue may yet end in court. Category C and D aircraft (Gulfstream IV, Challenger and Citation X aircraft (Piture Above), and the like) account for about 8,500 operations per year at SMO and half of its jet traffic. Violation of the ordinance, which the council says is proposed for safety concerns, would incur a $1,000 fine. The FAA has stated it will use "all available means" to prevent implementation of the ordinance. Proponents say the FAA's own guidelines call for runway safety areas of 1,000 feet at either end of runways accommodating category C and D aircraft. Santa Monica presently has none ... but it does have homes within 300 feet of the runway's ends.
There is no doubt there is noise problem moreover if you stay near a Military airbase.There is a report in newspaper that I read on how public who's home near an airbase complained about the noise when the Air Force conducting an exercise be it at day or night. But one thing that I'm notice is old jet aircraft like MD DC-10 or Boeing 727 or military jets contribute most of the noise pollution. New aircraft like Airbus 320 is most likely emitted less noise pollution.

Tupolev 214 Aircraft Will Do

With sanction cloud hanging over Iran by the western allies against the alleged nuclear enrichment project, Iran will do with Russian aircraft although it might be not up to western standard.

Iran's national airliner Iran Air will buy five Tupolev (Above Photo: Tupolev 214)passenger planes from Russia to meet high demand for domestic flights, Iran's state broadcaster said on Wednesday.

"Iran Air has various plans to complete its fleet and is to buy five Tupolev 214 passenger planes," Managing Director Saeed Hessami was quoted as saying on the web site of state broadcaster IRIB.

"The deposit has been prepared for transfer to the (Ilyushin Finance) company and they (the aircraft) will gradually join the fleet," Hessami said without giving any financial details on the deal.

Hessami did not mention any other plans to buy Tupolev planes from Russia.

In Moscow on Monday, a source with knowledge of the deal said Iran had started talks to buy 30 Russian Tupolev 204 passenger aircraft worth more than USD$1 billion.

The source, who asked not to be identified, said the deal was likely to be reached by the end of the year.

Government-owned Iran Air operates a fleet of Boeing and Airbus planes, while its Iran Air Tours subsidiary flies Tupolev 154 planes. Iran's airline sector has been under US sanctions for almost three decades, preventing it from buying new US planes or spare parts.

So, what else you can do if you're under that circumstances.

Flying and Radiation Risk

High flying and radiation risk is not a new feared topic. Its been circulated in aviation world for a long time.
Physicist Calls for Airline Industry to Educate Workers about Radiation At the high altitudes and latitudes commercial airlines fly, crews are subjected to higher-than-normal radiation levels from the sun and cosmic rays.
Physicist Robert Barish believes airline crew members are exposing themselves to more radiation than almost any other occupation and is calling for the airline industry to better educate workers about radiation.
Most careers have an occupational hazard, but frequent fliers may be exposed to cosmic radiation and not even know it. We all know the risks when we fly, but one risk we don't know about comes from what's in the sky.
Captain Joyce May, a commercial airline pilot, says, "By the time you're at normal jet cruising altitude of, say, 39,000 feet, the total radiation is about 64 times greater than what it is at sea level." May fears fellow crewmembers and frequent business fliers don't know the risk of cosmic radiation from solar flares.
She says, "Aircrew members, by-and-large, are unaware of this issue."Robert Barish, physicist and author of "The Invisible Passenger: Radiation Risks For People Who Fly," says, "The sun is really a big thermo-nuclear device." Barish believes airline crewmembers are exposing themselves to more radiation than almost any other occupation. He says, "People who work in the nuclear power industry on an average basis are getting 1.6. There are people who fly in airplanes who are getting 2 or 3 or 4 milliSieverts per year.
So they are truly radiation workers."Everyone is exposed to some radiation every day. The sun constantly emits charged particles that intensify during solar flares. Normally, the earth's atmosphere absorbs much of this, but at the high altitudes and latitudes airliners fly, crews are subjected to higher radiation levels and possibly are at higher risk for developing cancer.
In Europe, it is mandatory flight crews be educated about cosmic radiation, but that's not the case in the United States. The risk is not the same for everyone. Casual fliers have nothing to worry about. Only people who fly at least once or twice a week.
This is a bad news for a commercial flight, but what about military, a fighter pilot sometimes fly at a high altitude without any cover, only wind shield!.
