The Boeing 737 twin-engine airliner is the bestselling jetliner of all time.


The 737 MAX aircraft family includes the 737 MAX 7, 737 MAX 8, 737 MAX 9, and 737 MAX 200 variations. The new range of aircraft is intended to deliver unsurpassed fuel efficiency for the customers in the single-aisle segment.

The 737 MAX development programme was approved by the company's board of directors in August 2011. Boeing rolled out the first 737 MAX 8 in December 2015.

The aircraft made its first flight in January 2016. The first 737 MAX 8 was delivered to Malindo Air in May 2017.

Boeing 737 MAX design

The super-efficient design of 737 MAX incorporates new winglet technology, delivering fuel-burn advantage. The fuselage is strengthened to accommodate new engines.

The expanded tail cone, along with the thickened segment over the flight control surfaces, improve steadiness of air flow, and avoid the vortex generators on the tail.

These modifications further reduce the drag and improve the fuel-efficiency of the airliners. The aircraft delivers an 8% a seat advantage compared to other aircraft in the single-aisle segment.

Flight deck and cabin of the twin-engine airliners

The flight deck can house the pilot and a co-pilot. It is equipped with a common display system (CDS) supplied by Honeywell Air Transport Systems. The CDS consists of six flat-panel liquid crystal displays.

The flight controls include fly-by-wire spoilers in place of a mechanical system to achieve weight reductions. The aircraft is equipped with anti-icing systems and electronic bleed air system to improve cabin pressurisation.

The cabin of the 737 MAX features the passenger-preferred Boeing Sky Interior. The interior boasts modern-sculpted side-walls, a spacious cabin with more headroom, swivelling overhead stowage bins and an LED lighting system. The larger bins provide more space to passengers for storing carry-on roll-aboard luggage near their own seat.

Reading-light switches are redesigned to avoid the accidental pressing of the flight-attendant call button. Other eminent features include new speakers and tamperproof air grill.

CFM LEAP-1B engines on the 737 MAX

The 737 MAX is powered by CFM International LEAP-1B engines. The integration of engines with the wing is similar to that of 787 Dreamliner engine with its wing. The engine reduces CO2 emissions by an additional ten to 12% in comparison with existing fuel-efficient single-aisle aircraft.

CFM International received type certificates from the European Aviation Safety Agency (EASA) and the US Federal Aviation Administration (FAA) for its LEAP-1B engine in May 2016.

Boeing 737 MAX landing gear

The 737 MAX is equipped with retractable tricycle-type landing gear. The main landing gear is strengthened to accommodate the increase in loads due to the larger engines.

The nose gear door design is modified to complement a larger engine fan. The nose landing gear is lengthened to 20cm to achieve the required ground clearance, while housing the larger engine fan.
