plane lost over atlantic

A tv. programme, last night on freeview went into reasons behind air frances atlantic flight 447's fatal crash. I only caught the show half way through, but it left me with food for thought.

They didn't go into the "high tech upgrade" that the airliner was about to be fitted with, or how the new speedometers would work.

So, would it be

1. a wheel that spins with the air current relative to that which the plane is going, the constant spinning would better aid any forming ice to spin off on contact.

2. Vibration technology? If the existing hole inlets were to vibrate, they might shake off the forming ice.

Note: The documentary informed the viewer that pure water does not freeze on it's own, but has to come into contact with something to form ice around it. We were shown unfrozen pure water at -19 celcius! I have no reason to doubt this.

3. With that in mind. Could something be put in front of the air intake, and have it remodulated to accuracy, but in such a way that if ice hits, being heavier it is spun of and due to it's extra weight should spin out further than the air intakes.

4. If the air intake does get iced over. Surely there is a mechanism which would allow it to change shape to break the ice off, and/or open at the back temporarily to let the debris through.

Note: We were told the plane recorded about 24 faults in about 4 minutes, and this would be too much for the pilots to cope with, but it all boiled down to these air intakes getting blocked so that the speed could not be measured.
This led to the plane falling out of the sky at a rapid rate. So my next hunt for solutions turns to this.

a. Could parachutes be emplaced at strategic points on the plane to slow its fall? And keep it's nose and wings up and at the right/best level?

Note: The plane is said to be lost in an underwater mountain range, and the black box which only transmits for a month or so after a crash, is said to have stopped transmitting. The programme failed to answer why no rescue crew reached it, nor why it was allowed to sink.

If parachutes were fitted, surely the plane would land in such a way that would be gentle enough to deploy floats for the plane, and evacuate.

While the time the black box transmits its position has been shown to not be enough, this should be increased.

Finally, I hope training for pilots for such events becomes standard, as with the equipment needed to train them. So far only fighter pilots get the necessary training. Also the computers could be programmed to set to a safe speed, from last known. As it was said that a drop of about 10 knots is enough to send the plane into a spin.

You raise a lot of points about air safety - lets hope the pilots and maintenance are getting better trained for these events. The points on the black box was very interesting also.

Lost: The Mystery of flight 447, repeated BBc2, 12.30 am, 2 June 2010.

Said to have crashed 1 June 2009. A multimillion eurodollar operation has failed to recover the craft.

fragmants found 750 miles off coast of Brazil. Rest said to be two miles under on sea bed.

Why doesn't the rescue party have a rescue sub-marine?

Why does the plane rely on fly by wire. Why not use a rope like ships. To time how many seconds the rope unravells. Then rewind it. Having made the speed calculation from how long it takes. This could then be keyed in or transferred to computer in case of emergency.

The problem was, though three pitot systems were used they were eactly the same thing repeated, and all in a similar place at the front of the craft.

Instruments are said not to move with automation this would mislead pilots upon malfunction of the equipment. In the storm the autopilot disengaged on its own. Critical safety features failed, electronics in an electrical storm???

If PITOT probes failed, and are necessary for other systems. Why didn't this message appear first?

Again a call for alternatives to be included. Vibration technology: If something can be made to flap rapidly between two sensors, and this rate can be measured to rate of speed. This could be put inside, and use springs -like a dj would onboard a ship with vinyl records. So that air currents would not confuser the readings. This would have tthe advantage of being able to be placed inside the craft. Thus, the elements would have no bearing on it.

All in all 'we' are relying too much on computers. A simple example is that a Switch to turn something off is safer than a button to shut it down. With items such as walkmans etc. The mechanical switch saved the batteries for longer as it took the power connection away. Computers seem to just basically ask 'am I working yes/no?' but need the battery connection to maintain even this control. Insidentally, this is why even modern batteries on such as mobiles start to wear out after a time, and don't last so long after recharge as they did to begin with.
