href="http://atwonline.com/operations/investigators-recover-missing-memory-module-air-france-flight-447">vinden van de 'zwart doos'</a> van de verongelukte A330 van Air France bijna <strong>2 jaar na het ongeluk</strong> en het<a target="_blank" href="http://www.bea.aero/fr/enquetes/vol.af.447/point.enquete.af447.27mai2011.fr.pdf"> vrijgeven van een (zeer beperkt) deel van de cockpit gesprekken en vluchtgegevens</a> door het <a target="_blank" href="http://www.bea.aero/en/enquetes/flight.af.447/flight.af.447.php">Franse BEA dat het onderzoek voert</a>, laait de discussie opnieuw op over de <strong>oorzaken van deze crash</strong>.</p> <p><img alt="AF447 black box" width="626" height="361" src="//www.ottenbourg.com/blog/uploaded_images/AF447_black-box.jpg" /></p> <p>Een deel van de punten uit <a href="//www.ottenbourg.com/blog/2009/06/mogelijke-oorzaak-crash-air-france.html">mijn eerdere analyse</a> werden intussen opgeklaard:</p> <ul><li>De bemanning was zich bewust van het <strong>slechte weer</strong> en probeerde er omheen te vliegen (geen probleem dus met de weer-radar)</li> <li>De <strong>boordcommandant</strong> was in een gereglementeerde rustperiode en was in het begin niet in de cockpit. Beide co-piloten zaten vooraan, de co-piloot die rechts zat was "Pilot Flying" (PF), de andere "Pilot Non Flying" (PNF).</li> <li><strong>Ijsvorming aan de pitot tubes</strong> ligt aan de <strong>oorzaak van de problemen met de snelheidsmeters</strong>, waardoor o.a. de automatische piloot het opgeeft. Maar dit op zich is geen reden om neer te storten.</li> </ul><p>Wat er daarna gebeurt is al iets duidelijker maar gezien de <strong>zeer beperkte vrijgegeven informatie</strong> door de BEA, is het nog veel te onvolledig om nu al definitieve conclusies te gaan trekken. Voor sommigen gaat het duidelijk over een fout van de piloot (PF), maar zover wil ik nu nog niet gaan...</p> <p><strong>FEITEN</strong></p> <p>Wat weten we intussen meer?</p> <ul><li>Tien minuten nadat de captain is gaan rusten, we zitten intussen al iets meer dan 2u in de lucht, <strong>vallen de automatische piloot en automatische stuwkracht uit</strong>. Hierdoor verhoogt de stuwkracht van de motoren automatisch met enkele percenten tot de maximale "klim"-stuwkracht.<br />De 'stall' (overtrek) waarschuwing gaat af en de gemeten snelheid zakt abrupt tot amper 60 knopen.</li> <li>Het vliegtuig (FL350) <strong>begint (snel) te stijgen</strong> maar de bemanning lijkt dit te kunnen stabileren rond FL375 (na ongeveer 45 seconden). De co-piloten proberen de boordcommandant te bereiken.</li> <li>Enkele seconden later gaat opnieuw de "stall warning" af en ditmaal zet de PF de <strong>stuwkracht van de motoren op maximaal</strong> (TOGA) en <strong>trekt de neus van het vliegtuig omhoog</strong>, en blijft deze pitch-up positie behouden.</li> <li>De neus van het vliegtuig bereikt 40°, de verticale snelheid wordt (negatief) -10.000ft/minuut, m.a.w. het vliegtuig daalt snel in overtrokken toestand. De captain is intussen terug in de cockpit.</li> <li>Twee minuten na het begin van de problemen, brengt men de <strong>stuwkracht van de motoren naar een minimum</strong> (IDLE) en <strong>wordt de neus iets naar beneden gebracht</strong>.</li> <li>1,5 later minuut passeert men FL100 (3300m hoogte) met nog steeds een pitch-up van 35°</li> <li>Nog één minuut later crasht het toestel op de oceaan. De laatst gemeten info was een verticale snelheid van -10.912ft/min, 16° pitch-up en snelheid van amper 107 knopen.<br />De Airbus A330 is, zoals <a target="_blank" href="http://canadagboek.blogspot.com/2011/05/af447.html">Lode</a> het schreef, letterlijk vertikaal uit de lucht gevallen en tegen 200 km/h te pletter gestort.</li> </ul><p><strong>PILOT ERROR?</strong></p> <p>Als je dit leest lijkt het erop dat de <strong>bemanning</strong> (toch zeker in het begin) <strong>verkeerd reageert bij het overtrekken</strong> (stall) van het vliegtuig. Door het omhoog brengen van de neus (en het pitch-up effect van de motoren), wordt de stall enkel maar versterkt. De correcte reactie is eerst de neus naar beneden brengen, en ev. nadien de stuwkracht van de motoren verhogen om snel terug (aerodynamische) snelheid te maken.</p> <p>M.a.w. vanuit het standpunt van elke piloot is <strong>hun reactie moeilijk begrijpbaar</strong>... <br />Er is <strong>meer aan de hand</strong>, want de vliegtuigen van tegenwoordig zijn heel complexe staaltjes van technologie.</p> <p><strong>BIJKOMENDE AANWIJZINGEN</strong><br /><br />In het <a href="http://www.bea.aero/fr/enquetes/vol.af.447/point.enquete.af447.27mai2011.fr.pdf">voorlopige BEA rapport</a> licht men (denk ik) een (bijkomend) tipje van het ontbrekende puzzelstuk op...</p> <ol><li><strong>Er <u>ontbreken</u> heel wat <u>belangrijkste periodes</u> tijdens deze laatste 3 minuten. Alsook heel wat <u>gesprekken</u> tussen de piloten.</strong><br />Ik kan me moeilijk inbeelden dat er onderling niet meer gesproken werd, of dat de boordcommandant geen insctructies geeft als hij de cockpit binnenkomt.<br />Heel wat technische details ontbreken, niet alles is helemaal waarheidsgetrouw of chronologisch weergegeven en bepaalde passages leiden tot 'veronderstellingen' of verwarring.<br />'k Ben ook benieuwd naar hoe de <a target="_blank" href="https://lvb.net/item/7530">automatisch verzonden ACARS berichten</a> passen in het geheel.</li> <li>BEA rapport : <strong>A 2 h 12 min 02, le PF dit "<u><em>je n’ai plus aucune indication</em></u>", et le PNF "<u><em>on n’a aucune indication qui soit valable</em></u>". </strong> en wat later <strong>A 2 h 13 min 32, le PF dit "on va arriver au niveau cent". Environ quinze secondes plus tard, <u><em>des actions simultanées des deux pilotes sur les mini-manches</em></u> sont enregistrées et le PF dit "<u><em>vas-y tu as les commandes</em></u>"</strong>. <br />Werkten er meer instrumenten niet meer naar behoren, buiten de snelheidsmeter(s)! Kreeg men ook verkeerde informatie op de 'primary flight displays' (PFD) zoals de horizon, verticale snelheid, edm?<br />De PF zat rechts en bestuurt het vliegtuig, maar blijkbaar bewaart de zwarte doos enkel de getoonde gegevens van de instrumenten van de linker stoel en die van de standby-instrumenten. Zag iedereen hetzelfde? Werkten de joysticks en flightcontrols van de linker co-piloot naar behoren?<br />Een nadeel van de Airbus-joysticks is dat er geen "feedback" is zodat de piloten van elkaar moeilijk kunnen 'zien' hoe ze juist sturen. Heeft dit tot (bijkomende) verwarring geleid?<br />Of waren er bijkomende technische problemen? Bv. (auto)trim, zwaartepunt vliegtuig,...? </li> <li>BEA schrijft ook nog : "<strong>L’incidence, <u><em>lorsqu’elle est valide</em></u>, reste toujours supérieure à 35 degrés</strong>".<br />Heeft de BEA twijfels over de betrouwbaarheid en juistheid van de geregistreerde gegevens van de zwarte doos?!<br />Welke data wordt aan de piloten getoond en welke data wordt opgenomen in de data recorder? Zijn dit steeds dezelfde? De extreme omstandigheden zorgden misschien niet voor een correcte weergave van de data.</li> </ol><p>Het <strong>laatste woord</strong> is duidelijk <a target="_blank" href="http://www.securiteaerienne.com/air-france-447-faut-il-tirer-sur-le-copilote/">nog niet gezegd</a> over <a target="_blank" href="https://fr.wikipedia.org/wiki/Vol_447_Air_France">deze crash</a>.</p> <p>Een <strong>menselijke fout</strong> zal het ook altijd zijn... En waarschijnlijk zal de <strong>verantwoordelijkheid verdeeld</strong> zijn tussen de constructeur (Airbus en onderaannemers), de operator (Air France) en de bemanning.</p> <p>De <strong>volledige schuld bij de piloten</strong> leggen is al te gemakkelijk. Maar vermits niemand de crash overleefd heeft, is dat wel de gemakkelijkste oplossing...</p> <p>De toekomst en het eindrapport van de BEA zal het uitmaken.

Deze silicaten hebben een smeltpunt van 1100°C terwijl het in een jet-engine tot 1400°C kan worden. De glasvormige kristallen plakken als het ware de motor dicht/vast, met een "flame out" tot gevolg.<br /> Ander probleem is de erosie van materiaal op de bewegende delen van een motor (schoepen, fan, rotor/stator,...) wat voor verlies van vermogen kan zorgen, tot zelfs oververhitting, brand,... en uiteindelijk uitvallen van de motor(en).<br /> Er zijn 2 precedenten geweest van passagierstoestellen die door een aswolk zijn gevlogen en waarbij alle 4 de motoren zijn uitgevallen: <a href="https://nl.wikipedia.org/wiki/British_Airways-vlucht_9" target="_blank">British Airways 9</a> in 1982 en <a href="https://nl.wikipedia.org/wiki/KLM-vlucht_867" target="_blank">KLM 867</a> eind 1989.</li> <li><strong>Onjuiste indicaties op de boordinstrumenten</strong> in de cockpit (wegens het verstoppen van bv. de pitot-buizen). Gevaar: onjuiste weergave van de snelheid van het vliegtuig, met alle gevolgen van dien (automatische piloot die uitvalt, allerlei valse alarmen,...) Verstopte pitot tubes liggen waarschijnlijk ook mede aan de oorzaak van de recente <a href="//www.ottenbourg.com/blog/2009/06/mogelijke-oorzaak-crash-air-france-af447.html">Air France crash</a>!</li> <li><strong>Structurele schade</strong> aan aanvalsboorden van vleugels, roeren,... waardoor het vliegtuig moeilijk(er) bestuurbaar wordt. Schade aan voorruit, waardoor piloten geen of minder zichtbaarheid hebben.</li> <li>Het <strong>fijne stof</strong> van de aswolk dringt door tot <strong>alle systemen van het vliegtuig</strong>. De luchtcirculatie raakt 'besmet', stof in filters, in de elektronica van het toestel met kortsluitingen tot gevolg,...</li> </ul><p>Gelukkig is de KLM-vlucht er met de schrik vanaf gekomen. Na het uitvallen van de 4 motoren en een daling uit de aswolk heeft de bemanning (een deel van) de motoren terug kunnen heropstarten en is men 'veilig' kunnen landen.<br /> Het had ook anders kunnen lopen...</p> <p><iframe width="640" height="360" src="https://www.youtube.com/embed/Pd3KJVB8AuE" frameborder="0" allowfullscreen=""></iframe></p> <p>Door een vulkanische wolk vliegen is dus <strong>niet aangewezen </strong>en <strong>best te vermijden</strong>!</p> <p>Op dit ogenblik is het overgrote deel van het<strong> Europese luchtruim nog tot zeker maandag gesloten</strong>.

De bemanning was genoodzaakt om <b>op standby instrumenten</b> te vliegen en keerde terug naar Tokyo.<br />Als gevolg hiervan, publiceerde Airbus trouwens in 2007 een nieuwe checklist <b>ADR 1+2+3 FAULT</b> (<a target="_blank" href="//www.ottenbourg.com/blog/uploaded_images/QRH_219.pdf">PDF</a>) in de QRH!<br />In 2007 was er ook nog een onderbroken opstijgmaneuver (<i>aborted takeoff</i>) omdat er een snelheidsverschil werd vastgesteld.

In september 2007 raadde Airbus haar klanten aan om de <b>pitot tubes van de A320 te vervangen</b> door nieuwere modellen. Air France, net zoals de meeste luchtvaartmaatschappijen, deed dit niet op hun A330/A340-vloot, en <a target="_blank" href="http://alphasite.airfrance.com/s01/communiques-de-presse/#communique2640">trekt nu zijn paraplu open en schuift de hete appel door naar Airbus</a>.</li> <li>Air France (en vele anderen, <a target="_blank" href="http://www.tahitipresse.pf/index.cfm?snav=see&amp;presse=27783">ook ATN</a>) <a href="http://www.airfrance447.com/06/09/air-france-to-replace-speed-sensors/">vervangt nu toch snel</a> ('preventief') de "oudere pitot tube" modellen ook op A330 en A340 toestellen. Kwestie van de <b>publieke opinie</b> gerust te stellen.</li> <li>In het ergst geval (3 pitot tubes verstopt) is het nog altijd mogelijk om een<b> indicatie van snelheid en hoogte</b> te krijgen, dankzij de <a target="_blank" href="https://en.wikipedia.org/wiki/Global_Positioning_System">GPS</a>.

Het lijkt er eerder op dat het vliegtuig in vlucht <b>in stukken is gebroken</b>, waarschijnlijk door de extreme (aerodynamische) krachten op de roeren (<i>Flight controls</i>).<br />Misschien <a target="_blank" href="http://www.popularmechanics.com/technology/industry/1303226/">overcorrigeerde</a> (ALTERNATE LAW zonder protectie!) de bemanning ook zoals oa. in de crash van vlucht <a target="_blank" href="http://www.ntsb.gov/publictn/2004/AAR0404.htm">AA597</a> waarbij het richtingsroer helemaal afbrak en dit toestel crashte!</li> </ul><p><b>CONCLUSIE</b><br /><br />Wat er volgens mij is gebeurd: De A330 vliegt 's nachts door een storm.<b> Ijsvorming in de pitot tubes</b> (geheel of gedeeltelijk) zorgt voor <b>compleet verschillende gemeten snelheden</b>. De boordcomputers geraken hierdoor 'verward', stoten foutieve systemen/computers af (PRIM1, SEC1, ALTERNATE LAW tot gevolg) en geven de controle daarna uit handen (automatische piloot slaat af, flags op instrumenten) aan de piloten. Gelijktijdig gaan er natuurlijk ook heel wat <b>alarmen</b> af (o.a. '<i>stall</i>', 'speed disagree',...) die gelinkt zijn aan deze "gemeten" snelheden.<br /><br />Wat er daarna volgt is (nog) onbekend en (voorlopig) gegis... Heeft de bemanning deze <b>verkeerde snelheid</b> <i>toch</i> <b>voor waarheid genomen en intuïtief gevolgd</b> (tegenstrijdige alarmen, turbulentie, nachtvlucht, vermoeidheid, gebrek aan ervaring, stress, desoriëntatie), met waarschijnlijk een "stall" tot gevolg:</p> <ul><li>ofwel een "<i>low speed stall</i>" van het toestel door een te lage (aerodynamische) snelheid</li> <li>ofwel een "<i>high speed stall</i>" waarbij de maximale structurele snelheid van het vliegtuig werd bereikt</li> </ul><p>In het eerste geval valt het toestel al spinnend naar beneden, in het 2de geval breekt het in stukken.<br /><br />Hopelijk worden de <span style="font-weight:bold;">zwarte dozen</span> teruggevonden waardoor het onderzoek vooruit kan.<br />Voor piloten is het altijd <b>interessant</b> om <b>incidenten te analyseren</b> (wat kan er allemaal misgaan) en <b>conclusies</b> te trekken (wat is de <b>beste manier om te reageren</b> als mij hetzelfde zou overkomen).</p> </div> <!-- END OUTPUT

Een prachtige website trouwens. Ikzelf ben van opleiding ingenieur (UGent1975) met specialisatie meet- en regeltechniek en was mijn hele loopbaan werkzaam bij een groot Amerikaans petrochemisch bedrijf verantwoordelijk voor de technologie selectie, het ontwerp en implementatie van de meet-, regel-, controle- en beveiligingsapparatuur voor petrochemische installaties, je zou het de cockpit met randapparatuur van deze industrie kunnen noemen. Deze industrie heeft te maken met ongevallen met grote consequenties maar ook met bijzonder duur kostenplaatje bij het stilvallen van een fabriek. Het stilvallen van een middelgrote chemische fabriek kost al gauw 1 M$ per dag. Met andere woorden de keuze en het ontwerp van bijvoorbeeld de snelheidregeling van een turbine wordt zowel door veiligheids- als bedrijfszekerheidscriteria bepaald. Ik heb de evolutie meegemaakt van de technologie van volledige controle van de boordoperator (de piloot van onze industrie) tot wat jullie de fly by wire technologie noemen. Uiteraard zijn daar enorm veel variaties.Ik zie veel gelijkenissen maar ook verschillen hoe wij tegen directe oorzaken van het gelijktijdig falen van redundante systemen zoals verschildruksensoren aankijken. Als ik je verhaal lees, zonder alle afkortingen daarom te kunnen plaatsen, zou ik mijn focus bij een onderzoek van zulk een ongeval niet alleen of hoofdzakelijk richten op het gelijktijdig uitvallen van de sensoren, maar evenzo, misschien meer op de regellogica, de beveiligingslogica, de alarmeringslogica en hoe de boordoperator kan en moet omgaan met abnormale proces- en falingssituaties (bij een combinatie van hoge stress en hoge complexiteit zien wij vaak een heel hoge kans op falen).
