Air India B787 crash Ahmedabad

[RB001]

I'd be more concerned about who was serving the drinks.

"Are there any bartenders onboard today? Please identify yourself..."

Evidently, it only takes a few minutes to learn how to operate an aircraft...

I recall Bob Hawke saying something similar to that back in '89.

The bean-counters are listening and watching...!

If the airline uses multiple FOs or SOs instead of multiple Captains for long haul ops, then the FO being left in charge will require an ATPL.

Earlier aircraft had contact sensors on these sorts of switches, but technology has come a long way and now they would likely be Reed switches or possibly even Hall effect switches as these can output a digital signal. Given that when these fuel control switches are moved to the run position the FADEC uses this information to commence the ignition/start up sequence of each engine it is quite possible that a Hall effect switch sensor could be what is fitted - or there is no sensor on the actual switches and instead down stream of the switch there is a sensor or takeoff that basically says "I'm getting power now - so therefore the switch has been moved from cutoff to run"

@AviatorInsight - if you happen to be talking to any LAME's who are really clued up on the electricals it would be good to ask them which method is used to detect that the switch has been moved?

I'm not a pilot but trying to make sense of the way the fuel switches work on the 787-8 suggests optic fibres to the EEC + FADEC. There seem to be 2 fuel valves per engine one graduated and the other on/off. I thought I'd read that the graduated one at the v least would respond to a drop in fuel pressure by constricting the flow. In this sense would it be at all possible that something similar happened due to vapour which the computers then responded to by closing both valves until the fuel pressure got restored ? It's not inconceivable the following 10s delay was the time taken to purge vapour from the lines and reestablish or reopen the valves once fuel pressure was restored. I don't think the spring loaded switches in the coughpit would have had to move for any of these changes to have taken place, although the pilot flying would have lost his instrumentation when the RAT deployed as only the left hand arrays remain on

I know this is an old thread and I am a bit reluctant to reopen it until more verified info comes out but youtube throws me new videos on it occasionally. The theories continue......

I wish people would wait until the investigation is completed. I've seen two programs on TV recently stating that one of the pilots committed suicide. There are other possible scenarios but it doesn't stop the media from making a $ in the meantime..

Two sources that are not well regarded.

Yes but.......... I don't think you can blame people being hungry for information, particularly if they are flying soon (particularly on that type of aircraft).
Keeping it 'damped down' can also serve those who are interested in leaving a particular impression in the public's mind. The video I posted actually raises alternatives to the current 'popular' impression.

Theories can be fine when you have no hope or prospect of knowing what happened... But in all probability, we will find out what happened in this case and it will be supported by evidence. Not sure what theories achieve in this circumstance.

I thought that too. However they make the argument that not as much information has been released as usual at this stage in investigations and this hints of suppression of 'uncomfortable information'. I have no idea if that is true but there are certainly very powerful factors/world events in play.

Just a few more conspiracy stories. Some of them can be very hurtful to families of the crew particularly this one by an Australian Expert.

Even if you really were convinced it was true what good does it do to publicly say that before all facts are in. Despicable.

yes - but the video linked is posing the opposite - i.e. not crew related

Still unproven and adds nothing to the eventual result.
