Certo che i piloti ci si sono messi di buzzo buono, ma gli automatismi ci hanno messo il carico da undici.
In
http://www.pprune.org/rumours-news/5...s-air-phl.html sono anche annoverati alcuni interventi interessanti su 'go-no go' (abort fino a 80 per qualunque avaria, fino a V1-20 per tire failure, in prossimitā della V1 solo per avaria/fuoco motore, a velocitā maggiori solo per involabilitā), su 'evacuazione a/m' (quali uscite impiegare, cosa dire ai passeggeri di portare seco, cosa fare e dove andare una volta a terra, etc.)
Ma
Pilots played role in US Airways 1702 crash: FAA - 12/12/2014 - Flight Global č molto esaustivo e sconcertante.
...prior to take-off, captain John Powell noticed the aircraft’s primary flight display wrongly indicated 27R as the departure runway. ...
Se non ricordo male sull'M11, il primo dei magenta line con cui ho avuto a che fare, era data la possibilitā di preparare un 'piano B' "Secondary flight plan", molto comodo quando c'era la possibilitā d'impiegare diverse piste per il decollo e/o SID, attivabile se e quando necessario.
Sul 320?
...Co-pilot Lynda Fleming then correctly inputted 27L into the multifunction control display unit, but did not enter take-off V-speeds or a “flex temperature”, ...
...“The crew failed to accomplish this step and so the aircraft had no data available to compute and perform a flex take-off or display speeds,” ...
...when the captain advanced the throttles for takeoff, a warning chime sounded and a screen displayed “ENG THR LEVERS NOT SET; SET TOGA”, ...
...The copilot read the first part of this message aloud, but not the instruction to increase power. ...
...The captain responded that “the power is set”, adding that he had advanced the throttles to the flex position. ...
...At 80kt, an audible warning sounded “retard, retard, retard”. ...
...The first officer told the captain she had never heard that warning during take-off. ...
...“We’ll get that straight when we get airborne,” the captain responded. ...
(Nessuno nota che sul PFD non ci sono le velocitā caratteristiche. Chi chiama e quando V1, VR? Lo leggeremo sul final report)
...how high the aircraft climbed; one inspector says 20ft, another 70ft. Regardless, shortly after take-off the captain aborted. ...
...“The captain indicates that, once the wheels were off the ground, he had the perception that the aircraft was unsafe to fly, and moved the throttle to the idle position, which resulted in the accident,”...
...Surveillance video reviewed by inspectors showed that, shortly after take-off, the aircraft’s nose dropped and it began to sink... .
(Velocitā inf a 1,2 Vs?).
E anche se la velocitā fosse stata V>1,1 Vmca, datosi che:
Post #70:
..... THIS IS AN AIRBUS!
Several things happen when the jet is in Landing Mode.
As mentioned above there are both partial spoiler and full spoiler deflection capabilities and also once the ground air switch is made only 50% roll control is available.
A causa del vento al traverso di 15, raffiche 18 nodi non sarebbe stata necessaria una piantata motore per rendere molto problematica la condotta di quel volo.
...The nose then pitched up and, still sinking, the A320's tail struck the runway, followed by the main gear. The nose gear impacted last. ...
Inoltre (e imploro il Dr/Avv Alby di dire la sua in proposito):
...the captain reported for duty that day 45h after taking two prescription medications: midazolam, a sedating drug, and fentanyl, but did not notify US Airways, ...
BRRR!!!
Su un O-B(o)eing un "Firewall throttles!" avrebbe salvato la giornata.

Io controllo che il mio ASSO IV raggiunga 50 Km/h in 5" ogni decollo.
Salvo errori od omissioni
BUONE FESTE
