But that would have required the airline to provide more pilot training in flight simulators and to buy extra spare parts. airline 737 captain, said that Boeing would have installed new flight deck systems if some airline customers had wanted them. And Ewbank pointedly noted that on the Ethiopian Max crash flight, the clacker “was sounding continuously during the last minutes of flight.”Ĭost was certainly a major consideration when airlines told Boeing they wanted the Max to look the same to their pilots as the earlier 737NG. ![]() This capability is now standard on all Boeing models except the 737. But it lacks an upgrade Boeing introduced after the 1996 crash of a 757 in the Dominican Republic killed 189 people.įollowing that crash - Birgenair Flight 301 - Boeing decided pilots needed a way to acknowledge the overspeed warning and then silence the sound “to prevent crew distraction in critical troubleshooting times.” Senate committee this summer, he listed a series of specific shortcomings.įor example, the Max crew-alerting system activates a “clacker” making a very loud clicking sound to warn pilots when the jet is flying too fast. When Ewbank reiterated his concerns in a letter to a U.S. Similarly, he wrote, after the FAA granted exemptions, flight crew alerts were not upgraded to the latest regulatory standards on the Max. When Boeing certified the Max, the FAA granted it exemptions so that these older systems were approved without having to meet regulatory standards designed for later, more automated jets.Īfter the second crash, Boeing flight controls engineer Curtis Ewbank filed an internal ethics complaint alleging that an upgrade to the air data systems - called “synthetic airspeed,” a software system installed on Boeing’s latest jet, the 787 - might have prevented the crashes but was rejected because of the cost. In all, the aircraft already has 2.869 fixed orders from 57 companies, Gol Linhas Aéreas has 60 orders for this model.The systems that feed information to the pilot on a Max - providing, for example, the jet’s airspeed or its angle of attack, or a warning that something is faulty - are the same basic systems as on much earlier versions of the 737. Already in its look we can find new wings, a double winglet and engines with fairing similar to the 787 but keeping the traditional cheeks. Its new avionics are based on state-of-the-art Boeing aircraft such as the 787 and 747-8, incorporating innovations in its controls such as fly-by-wire but maintaining the same familiarity of its cockpit design. The Boeing 737 MAX is a new generation aircraft from Boeing that incorporates CFM Leap 1B engines and promises to be up to 25% more fuel efficient, thus achieving a 20% lower value per seat. The aircraft is being assembled in Renton (State of Washington), a Boeing assembly line that has already produced 707, 727, 747 and 757, today it is dedicated to the production of Boeing 737 and produces up to 42 jets of the type per month, from the start of its automation in 2018 it will be able to produce an incredible 52 Boeing 737 MAX. The entire avionics system was produced by Rockwell Collins.īoeing plans to roll out the first 737 Max 8 powered by CFM Leap-1B engines by the end of the year, with the first flight scheduled for early next year. ![]() The finalization was given from the connection of its cockpit systems, composed of 4 screens of 15 inches in the same multi-function style as its bigger brother of the new generation, the Boeing 787. 737 Max Flight Deck Renton Factory K66450īoeing announced that it has completed assembly of the first 737 MAX, including its electrical and electronic systems.
