MAX 7 Development
In July 2016 during the Farnborough Air Show, Boeing made an announcement on the redesign of the MAX 7, developed from the Max 8. Initially based on the 737-700, the MAX 7 can accommodate two more seat rows than the former.

On March 16 2018, the MAX 7 took its maiden flight in Renton, Washington. The aircraft flew around three hours over Washington. It landed at Boeing’s center in Moses Lake, Washington after reaching 250 knots and 25,000 feet. It completed a low final approach, systems check, and engine restart in flight.

MAX 7 Design
The MAX 7 features a high altitude package that enables the passenger to reach destinations with hot temperatures and high elevations without affecting range. It is equipped with higher thrust with additional bump thrust, advanced avionics for Required Navigation Performance (RNP) Authorization Required (AR), gaseous oxygen system up to twelve cylinders, alternate forward center of gravity for enhanced take-off weight, auxiliary battery for 60-minute standby power, and manuals and certification.

The aircraft has a 35.56-meter fuselage length, 3.8-meter diameter and 12.3-meter tail height. In order to carry the longer length of the fuselage, the structures were strengthened, and systems and interiors were modified. The remodeled MAX 7 has the wing and landing gear of the 737-8. The wing has a span of 35.9 meters. Instead of a single-door configuration, there is a pair of over-wing exits as a means of evacuation onto the wings.
