This occurred over the Atlantic during an Air France Flight to Paris from Buenos Aires some years ago. The incidence of airliner crews accidentally stalling their airplanes is almost non-existent except when in the unlikely event the flight control system malfunctions and misleads the flight deck crew into mishandling the emergency. It’s called the “ Maneuvering Characteristics Augmentation System,” and, in this instance, stall means aerodynamic stall or the airplane quits flying not engine failure. The Boeing 737 MAX is equipped with a flight control system designed to prevent the crew from accidentally stalling the airplane. The crash of Lion Air Flight JT610 is beyond a tragedy for the 189 souls aboard.
#737 max flight control system software
In January, Boeing discovered another software issue relating to a power-up monitoring function that verifies some system monitors are operating correctly.No lawyer in the world has as much experience with the Boeing 737 MAX control system malfunctions as Arthur Alan Wolk of The Wolk Law Firm.
#737 max flight control system update
Last month, Boeing decided to separate 737 MAX wiring bundles that the FAA had flagged by regulators as potentially dangerous before the jet returns to service, Reuters reported.īoeing said in February it would need a new software update to address an indicator light issue. Reuters reported in February a key certification test flight was not expected until April at the earliest and officials say it might not happen until late May or later.
It said in the autopilot issue “flight deck alerts and warnings are already in place to alert the crew if it did”.īoeing did not say when it expects the updates to be completed. The company said neither new software issue has been observed in flight. Boeing said the new software issues are not tied to a key anti-software system known as MCAS faulted in both fatal crashes.īoeing is adding new safeguards to MCAS in a software update. Boeing halted production in January.īoeing said it does not expect the issues to affect its current forecast of a mid-year return to service for the plane. The largest US planemaker has been dealing with a number of software issues involving the plane that has been grounded since March 2019. The manufacturer must demonstrate compliance with all certification standards.” The Federal Aviation Administration said on Tuesday it is in contact with Boeing as it “continues its work on the automated flight control system on the 737 MAX. Boeing said the software updates will address both issues. The United States planemaker confirmed to Reuters news agency on Tuesday that one issue involves hypothetical faults in the flight control computer microprocessor, which could potentially lead to a loss of control known as a runaway stabiliser, while the other issue could potentially lead to disengagement of the autopilot feature during final approach. The Boeing Company has said it will make two new software updates to the 737 MAX’s flight control computer as it works to win regulatory approval to resume flights after the jet was grounded following two fatal crashes in five months.
