About the Malaysia Airlines news report, 200 300 words, concise and clear

The plane is missing, the information is chaotic, and there are many search and rescue, but there is no result for the time being.

The set price is adjusted in units of 10 yuan. (Otherwise, (-200) 10 will be rounded).

y=50-(x-200)/10*5

If y>30, the equation can be solved, x<240

Today's elementary school students can't afford to be hurt. It's all over.

The Malaysia Airlines incident tells us that the accident and tomorrow do not know which will come first. Human life is accidental, but death is inevitable, we never know, every day will be our last day, so ask yourself every minute is alive and relieved? Carefree?

Or is it tangled? Regret? In fact, for life, except for life and death, which are major events, the rest are small things!

In the future, the international aviation community will be compulsory, hard and hard rules, bills, proposals, decrees, passengers must have the right to use special emergency broadcast communication equipment, so that at the last moment, passengers can call their loved ones, and the crew has no right to intervene.

Through the line running through the outer wall of the fuselage, the satellites that send signals to the outside world, the ground receiving equipment, the civil aviation aircraft flying in the nearby air, and the merchant ships sailing on the surface near the water are used to send emergency situations on the plane, the space position and attitude of the passenger aircraft, broadcast the will of the passengers, and transmit the process of the plane falling and forced landing.

For some passengers, there are voice, movement, breathing, ECG and other telemetry functions.

It is necessary to force satellites, ground receiving equipment, civil aviation aircraft flying in the air, and merchant ships sailing on the surface to install receiving and recording equipment for corresponding channels, so as to ensure that there are no blind spots in the world.

In the cabin of the aircraft, in the passenger area, several sending devices should be scattered and fixed, several sending devices, and at the same time put forward a request for manual starting, before the sending device is opened, and for the passengers who start the device, automatically start video recording and recording, so as to facilitate the retrospective and dispose of malicious operations.

The sending device has its own backup power supply, and there is a device outside the sending device that can be easily opened to prevent malicious start harassment.

Through relevant international laws and regulations, this kind of communication equipment is listed as the legal standard configuration of passenger aircraft.

This is the airworthiness regulatory standard for passenger aircraft.

That is, to realize, immediately guide the rescue and search and rescue work, do not wait for the long time to salvage and analyze the black box.

As for the difficulties of real-time transmission of passenger aircraft flight data such as large capacity, occupied bandwidth, and customer congestion, it is only sent throughout the take-off and landing process, and in the cruising process, mainly when the air attitude and speed vector, altitude, environment, engine working conditions, etc. are abnormal, it is automatically sent, so as to reduce the repetitive cycle and amount of information sent.
