The maximum ramp weight (MRW) (also known as the maximum taxi weight (MTW)) is the maximum weight authorised for manoeuvring (taxiing or towing) an aircraft on the ground as limited by aircraft strength and airworthiness requirements. It includes the weight of taxi and run-up fuel for the engines and the auxiliary power unit (APU).
Normally, the aftmost center of gravity for the Maximum Ramp Weight (MRW) lead to the critical ACN. Aircraft manufacturers publish the ACNs of their aircraft in their respective Aircraft Characteristics manuals. The ICAO Aerodrome Design Manual contains the source code of computer programs for the calculation of ACNs.
The maximum design taxi weight (also known as the maximum design ramp weight (MDRW)) is the maximum weight certificated for aircraft manoeuvring on the ground (taxiing or towing) as limited by aircraft strength and airworthiness requirements.
The weight of the aircraft is the common factor that links all aspects of aircraft design such as aerodynamics, structure, and propulsion, all together. An aircraft's weight is derived from various factors such as empty weight, payload, useful load, etc. The various weights are used to then calculate the center of mass of the entire aircraft. [37]

Zero fuel weight is the sum of operating weight empty and payload—that is, the laden weight of an aircraft, excluding any usable fuel. Ramp weight is the weight of an aircraft at the terminal building when ready for departure. This includes the zero fuel weight and all required fuel. Brake release weight is the weight of an aircraft at the ...
When the weight of the aircraft is at or below the allowable limit(s) for its configuration (parked, ground movement, take-off, landing, etc.) and its center of gravity is within the allowable range, and both will remain so for the duration of the flight, the aircraft is said to be within weight and balance. Different maximum weights may be ...
Takeoff weight components. The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, [1] is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits.
