Da se ne tučete, čep nema nikakav mehanizam za otvaranje: moraju se otšarafiti, iznutra, četiri šarafa, onda se čep gurne po vodilicama nagore dok ne prođe one kopče koje ga drže na mjestu. Tad postoji opcija da ostane otvoren na kip ili da ga se skroz ukloni

I jos - iznutra se ni ne vidi da su tu vrata (za razliku od normalnih vrata koja su u upotrebi za ukrcavanje / iskrcavanje, i onih za nedajboze situacije za evakuacije), skroz su zamaskirana i izgleda kao obican prozor. Da bi se uopste stiglo do otsrafljivanja prvo mora da se skine plasticna oplata tj. unutrasnji zid putnicke kabine.

cela rasprava je bila oko toga da li se vrata uvlace u avion ili izbacuju tj otvaraju napolje.

bilo bi totalno ludilo da se uvlace u avion tokom nesreca jerbo bi onda zaprecila izlaz putnicima.

Neki od dizajna vrata za evakuaciju se zapravo otvaraju prema unutra.

Ideja je da ih nakon sto se otvore izbacis komplet napolje.

Mislim da se nikad ništa ne IZBACUJE napolje, jer se ne zna na što bi moglo pasti

Uvijek se izbacuje, da ne zakrcuju izlaz:

Tek nameravaju da utvrde da li su ta četiri šrafa koji su bila predviđena da drže vrata uopšte ikada bila stavljena.

 

 

Vrata su pronađena:

A plug door is a door designed to seal itself by taking advantage of pressure difference on its two sides and is typically used on aircraft with cabin pressurization. The higher pressure on one side forces the usually wedge-shaped door into its socket, making a good seal and preventing it from being opened until the pressure is equalised on both sides. A non-plug door relies on the strength of the locking mechanism to keep the door shut.

On some aircraft, a complex hinge design allows half the door to open inward like a plug door, and the other half to open outward. Initially the door can be rotated to fit through the opening for the non-plug half so the whole door then opens outward; this is called a semi-plug door. Alternatively, the door may have locking hinged panels at the top and bottom edges that can make it smaller than the opening, so it may be swung outward.

Plug doors are used on most pressurized airliners, particularly for emergency exits and small passenger doors. However, since plug doors must open inward, the plug design is disadvantageous for large doors. Semi-plug doors are often used for the main passenger doors.

Mediji to zovu "čep" jer suštinski na tom modelu nisu u pitanju vrata predviđena da se koriste, ali inače ne predstavlja vrata čep (klinastog) tipa definisana gore jer se mogu otvoriti ako mehanizam za zaključavanje (šrafovi) ne odradi svoj posao.

 

Dakle, da jesu bila izvedena kao plug door iz gornje definicije, ne bi nikako mogla da se otvore pre sletanja.

Ispada da je ovo vec neko vrijeme sudska stvar,  evo juce isplivalo ovo:

 

Less than a month before a catastrophic aircraft failure prompted the grounding of more than 150 of Boeing’s commercial aircraft, documents were filed in federal court alleging that former employees at the company’s subcontractor repeatedly warned corporate officials about safety problems and were told to falsify records.

One of the employees at Spirit AeroSystems, which reportedly manufactured the door plug that blew out of an Alaska Airlines flight over Portland, Oregon, allegedly told company officials about an “excessive amount of defects,” according to the federal complaint and corresponding internal corporate documents reviewed by The Lever.  

According to the court documents, the employee told a colleague that “he believed it was just a matter of time until a major defect escaped to a customer.”

Emirates President Tim Clark, a powerful voice in the aviation community as the biggest buyer of widebody aircraft, said the accident on a Boeing Co. 737 Max aircraft on Jan. 5 marks a setback for the manufacturer just as it seeks to improve operations.

“They’ve had quality control problems for a long time now, and this is just another manifestation of that,” Clark said in an exclusive interview at his office in Dubai. “I think they’re getting their act together now, but this doesn’t help.

FAA je, žele to pokazat, nakostriješena na Boeing

 

"Proudly All Boeing" prijevoznik otkazao je sve letove do vikenda, a po svemu sudeć neće baš letjeti puno ni kad vikend prođe

mozda ce boeing morati da daje padobrane putnicima na ulasku u avion uz odgovarajuce instrukcije sta da rade ako ispadnu usput

I ta FAA je jednako kriva, ostavljajuci Boeingu da sam sebe proverava u velikom broju slucajeva. Ceo sistem je truo i previse je tu ljudi koji samo tako znaju da rade. Ovo je isti mindset koji je izazvao krizu 2008.
