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
