FAA to review Boeing 737 MAX 10 crew alerting system with synthetic angle of attack

The Federal Aviation Administration (FAA) announced on Friday that it will review the new crew alerting system for the Boeing 737 MAX 10, including a synthetic angle of attack feature.

The review follows a congressional decision in 2022 to exempt the MAX 10 from an updated cockpit alerting standard, allowing Boeing more time to develop an alternative solution.

Boeing’s improved alerting system is intended to provide pilots with clearer and more reliable data during critical phases of flight.

Congress has required that aircraft be retrofitted with safety enhancements within three years of MAX 10 certification.

The FAA will also review and certify design changes that incorporate these mandated safety improvements across the broader 737 MAX family.

Boeing is facing continued certification delays for the MAX 7 and MAX 10, partly due to engine de-icing issues. The 737 MAX 10 is the largest version of the 737 line, stretched beyond the MAX 9 to fit up to about 230 passengers in a single-class layout.

It uses the same engines and avionics as the rest of the MAX family but adds a longer fuselage and a revised landing-gear design that gives the airplane enough clearance during takeoff. Its size puts it close to the lower end of the Airbus A321 in capacity, aiming to offer more seats with the fuel efficiency improvements introduced across the MAX series.

In October, the FAA authorized Boeing to increase 737 MAX production rates to 42 aircraft per month.
