Flight recorder


Recommended Posts

All credit to the American-built Remora 6000, by Phoenix International, after the plane was found at about 12,800 feet  down,
Team includes a representatives from British and Brazilian air accident offices, Airbus, Air France, a U.S. sonar specialist and a psychologist. Plus wait for it Four French police officers and three from the gendarmerie to safeguard any wreckage retrieved.

Really great news I for one am happy these recorders have been found. Given that they are designed to withstand immersion up to 20,000ft I am hopeful the data will be intact and can provide some answers.

Surely praise must also go to Air France and Airbus who have both gone way beyond their duty to keep searching after the ULB's went dead. Well done to both.

I watched France 2 news last night and the medicine ligiste said that the bodies, medically were in a good state due to lack of oxygen in the water and the temperature of the water too. He added that what meant 'in a good state' to his profession and what it would mean to the families was quite a different thing.

One young woman who lost her fiance wanted his body leaving where it was. Others want them bringing up and I suppose burying.

They are very deep in the ocean and I was wondering if they could be brought up 'intact' or the pressure difference would damage them even more. I am for leaving in place.

Heard more tonight on Radio 4 news. The auto pilot had switched itself off. The co pilot was doing their best, which I took to be wrong and was  calling for the captain, but when he arrived it was too late.

Very sad., very very sad.

[quote user="powerdesal"]Given that the stall warning is reported to have been sounding it seems very strange that anyone, with a pilots licence would pull up the nose. Could we be looking at control reversal????[/quote]

The flight data recorder will be showing the position of the controls, as well as the aircraft's attitude, so it will be evident if the pilot was pulling up deliberately.

The pitot tube(s) are reported as being blocked by ice. This seals in the pitot pressure(s) at the time they froze. The airspeed signal then increases or decreases only with altitude, as it is derived from the difference between pitot and static pressures.

Depending on when the icing occurred, the aircraft could have been flying with a false airspeed signal for some time, and stalled after it lost airspeed when climbing or turning.

If the aircraft was losing altitude and the ASI was showing something reasonable, the pilot would very likely have pulled up the nose. If the aircraft had climbed since the pitot tube was blocked, the ASI could have been showing a higher speed than actual (as the static pressure would be lower) in normal flight, causing the autopilot to reduce throttle settings. The stall warning could well have been missed due to other warnings and noise at the time. It has happened quite a few times before when pitot tubes were blocked.

What is amazing is that so much of the computerised control of an aircraft depends on a primary airspeed measurement obtained from a bit of pipe sticking out into the airstream.

Is it possible that people can lose their common sense or forget about simple mechanical items when being force fed a mass of electronic and digital data? Everyone has heard tales of cars in ridiculous situations because the driver believed the Satnav.

I also wonder if the pitot de-icing was working properly, or even turned on.

Finally the announcement that 'Pilot error after technical failure' was to blame,
 Air-France-crash-due-to-pilot-and-technical-failings.

though that doesn't explain why Captain Dubois took so long to return to duty? and reading this  Air-France-Flight-447-Damn-it-were-going-to-crash , incredible that the technical failure could all be in the Airbus design of the sidestick.

After thousands of miles a year for many years, a few near misses and not a few very nervous experiences, I stopped flying when I no longer had to.

I now stick to forms of transport which have brakes or anchors, so they can stay where they are when their engines stop.

Must admit now I have a touch of arthritis in my shoulder I have given up flying as well. [;-)]
