Ovi lavici vole da izlecu s piste. Avion je nov - isporucen u martu

Cudno izgleda iz ovog ugla, a vec se govori da nije izleteo s piste vec da su sleteli na vodu pre piste:



Lion Air B738 at Denpasar on Apr 13th 2013, overran runway and came to stop in sea
Lion Air B734 and Air Asia B733 at Surabaya on Oct 30th 2009, runway incursion
Lion Air B734 at Pekanbaru on Dec 13th 2009, overran runway
Lion Air B739 at Balikpapan on Oct 23rd 2011, runway excursion
Lion Air B739 at Padang on Jan 19th 2010, runway excursion on landing
Lion B734 at Pontianak on Nov 1st 2012, overran runway on landing
Lionair B734 at Pontianak on Dec 30th 2012, runway excursion on landing
Lionair B734 at Pontianak on Nov 2nd 2010, overran runway on landing
Lionair B734 at Pontianak on Nov 2nd 2010, overran runway on landing

Nema sta da se govori, nije svako krljanje izletanje sa piste.

Nije ni dohvatio pistu. Srusio se pre nje u veoma stabilnom letu ali 30m ispod glide slope.

The aircraft was directly received from Boeing on Mar 28th 2013 and was in operation for just about two weeks, it is a different one to the former PK-LKS/9M-LNB. The captain on the accident flight was highly experienced with more than 10,000 hours of flying experience, he was and is in good health condition.

Radar data confirm the aircraft was approaching runway 09 and suggest the aircraft was about 100 feet below a 3 degrees glidepath descending at 700 feet per minute at a speed between 126 and 135 knots over ground, descending through 200 feet MSL about 1nm short of the touch down zone and 0.6nm short of the sea wall.

Sta god se desilo, bitno je da su svi preziveli

Kako je moguće da se desi da sleti ranije, a let je bio kako kažeš stabilan? To kapiram da je sve bilo ok, nije bilo extremnih dešavanja koja bi uticala na koncentraciju....
Zar nema neko pravilo tipa sleće se u 1/3 piste bla, bla, bla kako bi se izbegli ovakvi scenariji.

Možda je u pitanju onaj atmosferski fenomen (ne mogu da se setim naziva, pisao je Zuzazu o njemu detaljno), kada u trenutku gubiš uzgon i padaš kao cigla. U svakom slučaju, važno je da su braća Indonežani živi i zdravi.

Ako je ovo tacno:

.....the aircraft carried 101 passengers and 7 crew....... at a speed between 126 and 135 knots over ground....

Ono sto ce svakom iskusnom soferu zapasti za oko (a @ftj to najbolje ume da prepozna) je mala brzina u prilazu

Sa 110 putnika, racunato bez tereta i minimalnom dozvoljenom kolicinom goriva, avion je tezak 54 tone na sletanjum sto bez korekcije vetra daje brzinu u prilazu Vref 133 + 5 = 138 kts

Sa 126 kts nece stolirati ali je blizu.

Od prilike tako kaze i moj kompjuter....

Pajo, let je kontrolisan jer je imao nepromenjenu vertikalnu brzinu (V/S) od 700ft. Znaci, nije menjao pitch (ugao aviona) jer bi to dalo promenu V/S. Da je leteo u nekom drugom modu (LVL CHG)snizavanja ne bi imao konstantnu V/S pa je to nekontrolisan let prema zemlji. Ovo su inace i najcesci udesi i zovu se CFIT (controlled flight into terrain) - cini se da je sve u redu, ali vreba neki vrag kojeg si prevideo Ipak je i kapetan imao oko 10.000 sati, nije malo.

Inace. postoji pravilo i to je obaveza, da se gadja touchdown zona. Na fotki mozes videti na pocetku piste levo i desno od centralne linije, nekoliko belih isprekidanih linija. U tom polju moras da sletis i to je prvih 1000ft (300m) piste.

@snork - microburst. Po poslednjem meteo izvestaju jesu imali uslove za microburst a to je blizina oblaka tipa Cumulonimbus

A sta je stvarno bilo, cuce se narednih dana (mada sve manje verujem u istinu)

Blagodarim.

I zbog cega je pao na kraju? Zbog male brzine prilaza?

To ce se tek saznati. Ako je do vremenskih uslova, kao sto kaze zuzazu bilo je uslova za ovaj fenomen:

Ali je jos rano govoriti o bilo cemu. Pojasnicu i CFIT udes:

Jedan od primera CFIT udesa:

A evo i "slikovito" sta moze da uradi windshear/microburst:

The crash happened just after 5.15pm AEST when the Boeing 737, which had come from the popular shopping town of Bandung, West Java, apparently ditched short of the Ngurah Rai runway after the pilot reported engine troubles.
