FAA pilots are on board during these flights.
On November 22, Boeing received permission from the US Federal Aviation Administration (FAA) to conduct certification flight tests of the 737 MAX 10 aircraft, and less than 24 hours later the first flight took place. True, for some reason Boeing did not inform about the start of certification flights in a timely manner: the company waited four days.
On November 28, Boeing posted a video on Twitter (X) showing the Boeing 737 MAX 10 embarking on its certification flight. During these tests, Federal Aviation Administration pilots are on board the aircraft to record critical flight data.
It is not known how long the Boeing 737 MAX 10 certification flight test program will last, but the manufacturer plans the first deliveries of the aircraft for 2024.
