"The nose is turning itself down and they are having to fight it".

Modern jetliners have redundant measurements to help pilots spot and disregard a single reading that looks unlikely and possibly erroneous.

Even with modern Global Positioning System tracking, planes need to calculate their precise speed through the air.

These sensors measure the angle of attack of planes when climbing to ensure that they do not attempt to fly too steeply and stall.

Newsinflight reported another aircraft was deployed to transport the 143 passengers of the Lion Air to Jakarta. It's still possible the FAA may order the Chicago-based planemaker to redesign the equipment or software as investigators piece together details of the October 29 accident, which killed 189 people.

However, this new reminder from Boeing raises questions about the pilots' actions, how the flight crews are trained and if the maintenance that was performed was adequate. The agency gleaned the information on the plane's previous trips from the flight data recorder retrieved from the wreckage last week.

While there were no signs of an explosion in the air, the plane appeared to have hit the water with huge force, he said. Scores of body bags have been gathered but so far only 14 individuals have been identified. Once that happens, it may try to right itself by pushing the nose down, reports the Straight Times. "People panicked. It dropped about 400 feet", said Gaharu, adding that he had confirmed the height of the drop on a flight-tracking website.

The pilots' actions will also be studied.

Safety investigators said the plane may have hit speeds of 600 miles per hour before hitting the water.

At the meeting with family members, Mr. Tjahjono had said that information downloaded from the jet's flight data recorder was consistent with reports that the plane's speed and altitude were erratic after takeoff on its final flight.

The newspaper said the findings suggest investigators could be looking at a software problem or a mistaken interpretation by flight crew as having played key roles in the Lion Air crash.

"We are formulating, with NTSB and Boeing, detailed inspections regarding the airspeed indicator", he said, according to Reuters.

The FAA directive applies to about 250 Boeing 737 Max 8 aircraft operating worldwide. After all, even if pilot reactions are proven to be contributing factors in this tragedy-responding inappropriately to the situation, for instance-that doesn't absolve aircraft manufacturers and the airlines of their responsibility to design systems that can minimize as much as possible precisely that risk of human error. Some experts believe the hazard has increased with today's highly automated cockpits.

Malfunctioning airspeed indicators have factored in several high-profile crashes, including two more than 20 years ago involving Boeing 757s.

The investigation is now focused on flight data from one of the black boxes, found last week. They have not yet found the other one, which captures conversations in the cockpit and ambient sounds such as a change in engine noise.

"They should have been completely engaged in what was going on inside that cockpit, and any kind of warning that came up, they would have been wise to pay attention to it", Curtis said.
