Problems solved by technology

However, the accuracy of these passenger weight assumptions is unknown as airlines do not weigh individual passengers and carry-on luggage individually
Additionally, true weight values ​​may vary significantly depending on passengers from different world regions, or baggage restrictions of different airlines, further increasing the uncertainty of these standard weight assumptions

Embodiment Construction

[0027] The disclosed examples will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, disclosed examples are shown. Indeed, many different examples may be described and should not be construed as limited to the examples set forth herein. Rather, these examples were described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] The example systems and methods describe how the total mass of an aircraft can be determined when pushing the aircraft back from a terminal or when moving the aircraft in any scenario (eg, moving the aircraft to or from a de-icing area). The sensors on the pushback vehicle measure a number of variables that can be used in calculations in the equations of motion to arrive at the total mass of the aircraft. Instead of weighing all cargo and passengers / crew individually, which is impractical, the total mass...

Abstract

Systems and methods for aircraft mass determination. An example methods for aircraft mass determination at pushback includes determining an acceleration of a pushback vehicle while moving an aircraft,determining a pushback force applied by the pushback vehicle while moving the aircraft, and determining a total mass of the aircraft based on the pushback force, the acceleration of the pushback vehicle during pushback, and a coefficient of static friction between tires of the aircraft and a surface on which the aircraft moves. An example system includes a pushback vehicle coupled to an acceleration sensor and a force sensor, and a computing device having one or more processors to determine a total mass of the aircraft based on the pushback force, the acceleration of the pushback vehicle during pushback, and a coefficient of static friction between tires of the aircraft and a surface on which the aircraft moves.

Description

technical field [0001] The present disclosure relates generally to systems and methods for determining the gross mass of an aircraft while moving the aircraft, and more particularly, to determining the acceleration of a push-back vehicle and the resulting push-back vehicle acceleration that can be used to determine the gross mass of a fully loaded airplane. Example method of rear thrust applied by a vehicle. Background technique [0002] Developing optimal aircraft routes that minimize flight time, fuel burn, and related environmental emissions can improve air traffic and also help the aviation industry cope with increasing fuel costs. Optimal cruising altitude is based inter alia on atmospheric constants and aerodynamic drag coefficients that are determined and vary by aircraft type, while the resulting total lift and drag (units of force ) depends on the aircraft mass. Aircraft mass determination can be difficult to determine. [0003] The mass of an aircraft includes m...
