Someone is trying to sell new global technologies but hard sells and Chinks not sold yet.
危 has settled down, 机会来了.
A New world order is coming. Time to buy new technologies share, but which one?
But radar only covers 10 per cent of the planet. There are huge gaps over the oceans and desert, including in Australia. Moreover, the plane's secondary radar, like its separate ACARS communications system, can be shut down in the cockpit, as apparently happened with MH370, or by mechanical failure. This means only certain types of land-based radar can pick up the plane, mostly military facilities. Even then, the object can't be precisely identified. It will only be a blip on a screen. Satellites are even worse. The “pings” from an unidentified aircraft picked up by a satellite over the Indian Ocean last weekend could only be vectored into two vastly divergent arcs to the north and south.
The solution is a satellite tracking system that is used by about 60 per cent of planes – but was not on MH370. It broadcasts an aircraft's position, velocity and other information, second by second, and allows the aircraft to be located to within 10 metres. The aviation industry needs to embrace the technology as standard and develop a system that can prevent anyone in the cockpit shutting down the tracking system.
When countries co-ordinate a search mission, they're not always sharing information.
Malaysia's government has, justifiably, been lambasted for its missteps and mistakes. MH370 crossed its radar at 2.15 am, but it wasn't picked up by the four-person crew, who had fighter jets on standby, until later that morning.
But Malaysia's allies and neighbours have not shared satellite information in a timely fashion either. China took three days to release its grainy footage of debris in the South China Sea. It took four days for Australia to reveal images taken by a US satellite of large flotsam in the southern Indian Ocean. Thailand didn't share its knowledge that it picked up MH370 on its radar for 10 days, saying it was never asked.
It takes time to identify and analyse an image taken from space. However, China and US, the globe's great geo-political rivals, aren't inclined to share secrets – air defences and space-based surveillance hardware are some of the most sensitive military information around. Malaysia's Acting Transport Minister Hishammuddin Hussein said this week that his nation had “put our search effort above our national security” but bemoaned that they were the only country to do so.
There were passengers from 15 nations on MH370. In a globalised world, air disasters will require more international co-operation. New protocols for handling sensitive material between nations are needed. There are lives to be saved in search and rescue operations, and speed is of the essence.
Why doesn't the black box float?
The key to any aircraft investigation – the black box – can take years to find if a plane ditches in the ocean and its debris is not discovered for some time. Ocean currents can pull the plane wreckage hundreds of kilometres from the initial point of impact. In a handful of instances, the black box hasn't been found at all. Its beacon has a short range and sends out ultrasound. It's not connected to satellites, yet that technology is available and experts say it should be embraced.
