You can certainly climb without flaps, but you need thrust from the engines. No engines, no climb. The ram air generator deployed, indicating loss of engines. Flaps improve lift but also increase drag. Flaps shorten the takeoff roll. In the event of a dual engine out, reducing flaps reduces drag in order to extend the glide range.... But then why wasn't the gear retracted... Still many questions without answers yet. |

In a couple of the clips you can hear when the plane passes that it sounds like a old war airplane with a propeller flying by. That would be the ram air turbine (also called the "RAT"). Deployment of the RAT ONLY happens when an there is a total loss of engines or loss of hydraulics. It deploys automatically to provide just enough juice to power systems deemed "essential". The fact that the sole survivor mentions hearing a loud bang is consistent with the RAT deploying, it makes a distinct loud noise. The RAT will not deploy simply due to a loss of control.

Re: Air India 787 Jet Ahmedabad to Gatwick Crashes, Major Casualties Expected.
A preliminary investigation report has just been released that blames pilot error and reveals one of the pilots turned off the fuel switch(es) mid take-off. Cockpit recording reveals the pilot questioning the co-pilot about turning off fuel to the engines and the co-pilot denies doing it. Then an attempt is made to turn the fuel on but it's obviously too late to recover.

Re: Air India 787 Jet Ahmedabad to Gatwick Crashes, Major Casualties Expected.
Investigators say the lever-lock fuel switches are designed to prevent accidental activation - they must be pulled up to unlock before flipping, a safety feature dating back to the 1950s. Built to exacting standards, they're highly reliable. Protective guard brackets further shield them from accidental bumps. "It would be almost impossible to pull both switches with a single movement of one hand, and this makes accidental deployment unlikely,". That's why there need to be cockpit video recorders so every movement can be monitored. Weird they don't know who said what as usally relatives are asked to identify the heared voices. What if the switches moved on their own? Is that possible? |

Re: Air India 787 Jet Ahmedabad to Gatwick Crashes, Major Casualties Expected.
It's impossible for those switches to move on their own. I don't fly a Boeing but I have switches just like that in the Pilatus they're generally standard across the industry to prevent accidental movement. It's like a light switch but it's got a metal guard in the middle that requires you to pull on the switch and then flip it to the next position. The locking mechanism is so robust that I've seen the switches on the overhead panel of this design get bent by people bumping them with their heads when climbing it out of the seat but the switch did not change position. The report also states that they were Switched Off one after another with one second between it which does not sound like an accidental bump of the hand but a deliberate action. The big question now will be who turn the switches off and did they do it intentionally meaning did they mean to shut the engines off or were they thinking we were doing something else and flipped these switchs in error |
