Exclusive: Lion Air pilots scoured handbook in minutes before crash - sources

JAKARTA/SINGAPORE/PARIS (Reuters) - The pilots of a doomed Lion Air Boeing 737 MAX scrambled through a handbook to understand why the jet was lurching downwards in the final minutes before it hit the water killing all 189 people on board, three people with knowledge of the cockpit voice recorder contents said.

The investigation into the crash last October has taken on new relevance as the U.S. Federal Aviation Administration (FAA) and other regulators grounded the model last week after a second deadly accident in Ethiopia.

Investigators examining the Indonesian crash are considering how a computer ordered the plane to dive in response to data from a faulty sensor and whether the pilots had enough training to respond appropriately to the emergency, among other factors.

Following the second fatal accident, U.S. authorities are reviewing whether enough was done to ensure the plane was safe to fly, while attention has also focused on the training of the Lion Air crew and whether aeroplane manuals are clear enough.

It is the first time the voice recorder contents from the Lion Air flight have been made public. The three sources discussed them on condition of anonymity.

Since the situation had not happened before, and the plane was computer controlled, I wonder how one could "train" for it.

The angle-of-attack sensor is a wing-like device in the nose of the aircraft. It is supposed to prevent stall conditions.
