Martin Varsavsky posted this interesting article on his blog:
It is unacceptable to go on sending planes over the ocean without position trackers, real time weather information, ground based support and no satellite phones. It is wrong that in emergency situations pilots can only communicate with, say, Cape Verde control and not with their own airline, or even plane makers such as Boeing or Airbus. It is absurd that we don’t know where planes are when they fly over the ocean and even when they are on the ground we only know it within a few miles range but not exactly where they are because radars are so inaccurate.
Aircraft in transoceanic flights should send location, heading, speed and other relevant data by satellite; automatically and every few seconds. They should be capable of downloading real time weather data to increase the efficiency and safety of flights and pilot autonomy. Weather radar is a very primitive way to fly, especially without ground support. Weather radars from the plane should be contrasted with satellite info received in the aircraft. There should also be a secondary means for voice communication, also by satellite to be able to quickly contact an airliner crossing the ocean. Furthermore, making these flights safer should impact insurance costs, and increases in operational efficiency would lower fuel consumption.
In this post I present a few possible solutions to these problems. Of course, this is only one of many series of measures that can be taken to make these flights safer.
