The union for pilots at American Airlines says Congress shouldn't give Boeing an exemption to keep older-style cockpit alerting systems on new variants of 737 Max jets. Chicago-based Boeing has pushed to keep the same cockpit alarm systems in new 737 Max variants, even getting Congress to pass a two-year exemption in late 2020 to a modernization requirement. Boeing says it should be allowed to keep one common cockpit system on all 737 planes, even with the 737 Max 7 and 737 Max 10 variants that are in the Federal Aviation Administration certification process. Without more time, Boeing may be forced to redesign the cockpit alert systems. "Boeing needs to proceed with installing modern crew alerting systems on these aircraft to mitigate pilot startle-effect and confusion during complex, compound system malfunctions," said Allied Pilots Association president Capt. Edward Sicher in a statement.
