The maximum landing weight (MLW), also known as the maximum structural landing weight or maximum structural landing mass, [1] is the maximum aircraft gross weight due to design or operational limitations at which an aircraft is permitted to land. The MLW is set in order to ensure safe landings; if an aircraft weighs too heavy during touchdown ...
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.

ACNs depend on the landing gear geometry (number of wheels and wheel spacing), the landing gear load (that is dependent upon the aircraft weight and center of gravity) and the tire pressure. Normally, the aftmost center of gravity for the Maximum Ramp Weight (MRW) lead to the critical ACN.

The oxygen, cabin pressurization, landing gear control, aircraft health and trend monitoring systems are adapted from the G650. [43] The auxiliary power unit is a Honeywell HTG400G. [41] The cabin pressurization reaches 10.69 psi (0.737 bar). [44]
The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during the flight or ground operation. [ 1 ] [ 2 ] [ 3 ] An aircraft's gross weight will decrease during a flight due to fuel and oil consumption.
