Now You can weigh a 747 Aircraft as easy as 123
The 747 could be simply weighed by pushing it about 1 metre and then returning it to its original position.
Mass accuracies approaching 0.5% have been proven in the laboratory.
Sir Isaac Newton found that the acceleration of a rigid body is related to the net force applied to it by the expression
f = ma … (1)
where: f is the net applied force,
m is the mass of the body, and
a is the acceleration of the object.
This relationship is known as Newton’s Second Law.
It may also be stated as:
“The acceleration of a particle is directly proportional to the resultant external force acting on the particle, is inversely proportional to the mass of the particle, and has the same direction as the resultant force.”
As expression (1) states, the mass of an object can be determined if the applied force and the resulting acceleration are measured. The complication arises from the fact that not all of the applied forces are readily measurable. The net force applied to the aircraft includes not only the intentionally applied force, but also extraneous forces due to:
i) Kinetic friction in the wheels and bearings,
ii) Viscous friction in the wheels and bearings,
iii) Ramp inclination,
iv) Wind, and perhaps others.
It is the resultant force that must be known and, therefore, all extraneous forces must be adequately accounted for. Most of the R&D effort to date has been directed toward developing and verifying a method that will account for all of the applicable forces.
The features of this technology are:
- Provides accurate weight within seconds
- Connects to normal tug attachment during weighing process
- Can be repeated at any time prior to departure
- Requires moving the aircraft about 1 metre and returning to original position
The benefits are:
- Improved safety
- Optimum fuel loading
- Optimized aircraft loading to improve profits
