![]() ![]() Easy.Īll of this took under a minute, and everything appeared to be back to normal.Īt 1,500 feet of altitude, the takeoff portion of the flight was officially complete, and the first officer began the initial climb. So with the turn of a dial, the captain switched the primary displays to only use data from the working sensors on the right side of the airplane. In this case, the captain checked both instrument panels against the backup, and he found that the instruments on his side - the left side - were getting bad data. Each system is fed by an independent set of sensors. In the cockpit, there are three flight computers and digital instrument panels operating in parallel: two primary systems and one backup. Like all commercial aircraft, the Boeing 737 Max has multiple levels of redundancy for its important systems. A Boeing spokesperson said the company believes the system is still “a robust and effective way for the FAA to execute its oversight of safety.” ![]() Despite the two crashes, neither Boeing nor the FAA believes they’ve done anything wrong.Even still, Boeing only recommends a 30-minute self-study course for pilots on MCAS, rather than additional simulator or classroom instruction.Nowhere in its amended type certification of the 737 Max is MCAS mentioned. The FAA has admitted to being incompetent when regulating software, and, as a policy, it allows plane manufacturers to police themselves for safety.But its failure in both crashes was the result of Boeing and the Federal Aviation Administration’s reluctance to properly inform pilots of its existence or to regulate it for safety. MCAS is the new software system blamed for the deadly Lion Air and Ethiopian Airlines crashes.Since the 737 Max was the same plane type as its predecessors, pilots would only need a 2.5-hour iPad training to fly its newest iteration. In developing the Max, Boeing not only cut corners, but it touted them as selling points for airlines.It rushed the competing 737 Max to market as quickly as possible. Mistakes began nearly a decade ago when Boeing was caught flat-footed after its archrival Airbus announced a new fuel-efficient plane that threatened the company’s core business.
