Avion Air France dispărut de pe ecranele radarelor în largul coastelor Braziliei

Nu numai ca-s speculatii dar sunt chiar aberatii. sunt 2 aspecte luate in seama aici. Pilotii nu zboara niciodata intentionat intr-o zona de furtuna sau turbulente severe din 2 motive:

1. pentru a nu periclita siguranta zborului. o furtuna f puternica (exista astfel de furtuni si la peste 35.000ft) poate duce la avarii serioase. desi avioanele moderne rezista uimitor nu intri sa le vezi limita. oricum nu-ti da voie SOP la orice companie ai fi.

2. pilotii evita mereu zonele cu turbulente severe (chiar daca nu e furtuna pot si turbulente mari din cauza vanturilor puternice) ptr confortul (psihicul) pasagerilor si integritatea cabin crew-ului care-s mereu in picioare in timpul zborului si sunt expusi vatamarii. cateodata radarul si nici planul meteo nu arata aceste turbulente ("unexpected turbulance") si se mai intampla sa ai avionu dansand. asta se intampla mai ales deasupra Indiei si a Asiei de sud cand e sezonul musonilor, dar nu numai. atunci se procedeaza la schimbarea imediata a nivelului de zbor, se coboara.
in timpul zborului pilotii raporteaza mereu la atc (acolo unde este) cum e vremea la diferite flight levels, iar informatia este transmisa si utilizata si de celelalte avioane de pe ruta.

pilotii primesc meteo inainte de zbor ptr tot traseul ce o sa-l strabata. Ei o sa ocoleasca zona de maxim intotdeauna. pe radarul din cockpit aceste zone apar cu rosu. nu se intra niciodata intr-o zona rosie. o sa fac o poza si o sa va arat cum arata o astfel de zona cu meteo in care nu se intra.

PS: inca o data. daca nu stiti procedurile nu mai lansati sau sustineti tot felul de teorii preluate din media. e jenant. pilotii de la AF au fost cu siguranta profesionisti 100% si astfel de invinuri nu isi au rostul. desi este uman a gresi sa asteptam intai evidente in acest sens si pe urma comentam ce si cum.

Chiar...ce bine ar fi sa ascultam parerea specialistilor(piloti,controlori de trafic,etc).Eu ii rog sa o faca fiindca sunt destui pe aici .Oricum sunt doar pareri date la minimul de informatii care se cunosc.Probleme destule:meteo,navigatie,comunuicatii,constructii av,factori umani.Promit ca dau un premiu celui care va fi cel mai aproape de adevar.

nu prea e frumos sa dai un premiu pt cine ghiceste de ce au murit niste oameni...

Dupa cum am spus sunt speculatii. Trebuia sa scriu cu majuscule si cu bold? Nu cred ca cei de la Le Mode, Le Figaro, Ny Times sau Guardian lanseaza astfel de speculatii sau ipoteze fara o minima documentatie. Si da, e posibil sa fie si mortul de vina, s-a intamplat de atatea ori. Pilotii sunt si ei tot oameni, chiar si ei mai pot sa greseasca, de ce vi-se pare de neconceput teoria asta? Si daca e asa cum se spune, ca un pilot n-ar fi zburat niciodata printr-o furtuna, atunci ce cauta avionul ala acolo?

Deci radarul meteo de la bord arata cam asa:



Aditional mai afiseaza zonele de turbulente in nuante de magenta si windshear cu avertizare optica si acustica. In zonele rosii si magenta inchis nu se intra - de obicei - niciodata!

Imi amintesc acu cum imi povestea instructorul la formare planor cu ani in urma despre planoare intrate in CB si rupte in bucati de curentii de forfecare (ascendenti-descendenti)... desigur nu se poate compara.... doar la scara...

Pam pam pam pam!

de asemena niste informatii utile. sunt f tehnice ptr cei care stiu sa le citeasca si sa le interpreteze.

More details of the ACARS messages have become available on June 5th and suggest following events while the airplane was in cruise (note, there is no message regarding electrics, hydraulics or engine problems):

02:10Z: Autothrust off
Autopilot off
FBW alternate law
Rudder Travel Limiter Fault
TCAS fault due to antenna fault
Flight Envelope Computation warning
All pitot static ports lost
02:11Z: Failure of all three ADIRUs
Failure of gyros of ISIS (attitude information lost)
02:12Z: ADIRUs Air Data disagree
02:13Z: Flight Management, Guidance and Envelope Computer fault
PRIM 1 fault
SEC 1 fault
02:14Z: Cabin Pressure Controller fault (cabin vertical speed)

exista o controversa legata de tuburile pitot.

Starting in May 2008 Air France experienced incidents involving a loss of airspeed data in flight, in cruise phase on A340s and A330s. These incidents were analysed with Airbus as resulting from pitot probe icing for a few minutes, after which the phenomenon disappeared. Discussions subsequently took place with the manufacturer. Air France asked for a solution which would reduce or eliminate the occurrence of these incidents. In response to these requests, the manufacturer indicated that the probe model recommended for the A320 was not designed to prevent such incidents which took place at cruise levels, and reiterated the operational procedures well-known to the crews.

In the first quarter of 2009 laboratory tests suggested, however, that the new probe could represent a valuable improvement to reduce the incidence of high altitude airspeed discrepancy resulting from pitot probe icing, and an in service evaluation in real flight conditions was proposed by Airbus. Without waiting for the in service evaluation, Air France decided to replace all its probes and the programme was launched on 27 April 2009.

Submarine To Begin Air France Black Box Search

A French submarine with advanced sonar equipment is due to begin searching on Wednesday for the flight data recorders of the Air France airliner which crashed into the Atlantic Ocean last week, the French military said.

The nuclear-powered submarine Emeraude was dispatched to the area last week to help recover the "black box" flight recorders, which may contain clues to explain the disaster and which are believed to lie deep on the Atlantic ocean floor.

"The Emeraude will begin its patrol during the morning in an initial search zone of 36 km by 36," Christophe Prazuck, a spokesman for the French military said. He said the search zone would be changed daily.

If the recorders are found, unmanned robot submarines on board the Pourquoi Pas, a French exploration and survey ship which has also been deployed to the area, could be used to bring them in.

All 228 people aboard Air France flight AF 447 from Rio de Janeiro to Paris are believed to have died when the Airbus A330 aircraft crashed into the ocean after flying into stormy weather more than a week ago.

Brazilian military search teams have recovered 41 bodies from the sea and moved some of them to the archipelago of Fernando de Noronha off Brazil's northeastern coast, which is being used as a base for the search operations.

Several pieces of wreckage have also been found but a full understanding of the accident will depend on the black box recorders being recovered.

The doomed jet sent 24 automated messages in its final minutes on June 1, detailing a rapid series of systems failures.

Speed sensors that gauge how fast an aircraft is flying have become the focus of the investigation after some of the messages showed they provided inconsistent data to the pilots.

Pe de alta parte, au fost identificare corpurile capitanului Marc Dubois si ale unui steward (Le Figaro).

incredibil!
iar a aparut pe mail hoaxul din urma cu cativa ani... o captura din episodul pilot al Lost si cateva vorbe scris aiurea, despre pasagerul care a pozat momentul desprinderii cozii... oare cati or pica in plasa aceasta. detalii aici

Conform BEA, pe 2 iulie va aparea un raport preliminal "factual" privitor la accident.
