Tull og tøys settes nå i system etter at AF447 og MH370 forsvant sporløst. Emergency Locator Transmitter kan løse slike problemer. Enheten er festet til flykroppen og spretter av ved en pre-satt G-belastning som ved et havari. Den sender på nødfrekevensene og signalet plukkes opp av COSPAS/SARSAT som etter kort tid kan finne ganske nøyaktig posisjon for utsendelsen. Avanserte typer sender også sin GPS posisjon. Dette er mye mer nøyaktig enn den avstand et fly tilbakelegger på 15 minutter. Og veldig billig.....(Red.)
The UN agrees to create a global flight tracking system after disappearance
of MH370
The disappearance of Malaysian Airlines Flight MH370 with 239 people
onboard last year spurred a worldwide effort to create a better system to track
civilian flights. On Wednesday, some of that effort bore fruit. A UN committee
agreed to allocate a portion of the radio spectrum for global flight tracking to
prevent future disappearances.
The agreement was reached at the World Radiocommunication Conference in
Geneva. The UN International Telecommunication Union, which sets global
standards for communication technology, agreed to dedicate the frequency band
1087.7-1092.3 MHz for satellites and space stations to receive Automatic
Dependent Surveillance-Broadcast emissions from aircraft transmitters. Currently
aircraft only send these transmissions to other aircraft and air traffic control
stations, which limits their effectiveness when aircraft are traveling in remote
areas or over oceans.
ITU Secretary-General Houlin Zhao said in a statement that his organization
has "responded in record time to the expectations of the global community on the
major issue concerning global flight tracking. ITU will continue to make every
effort to improve flight tracking for civil aviation."
But some would disagree. After the disappearance of MH370, regulators and
airlines were criticized for responding too slowly to French tracking
recommendations after the crash of an Air France jet in 2009. Last September,
the European Union said it would pursue plans to impose mandatory flight
tracking in response to the MH370 tragedy.
The UN's aviation arm, the International Civil Aviation Organization, has
set a deadline for November 2016 for airlines to install tracking technology.
Those will include aircraft sending their position at least every 15 minutes, or
more in case of emergency.
French investigators recently confirmed a piece of debris that washed
ashore on Réunion Island is from MH370.
