AR asked:


Balance Graph is a allowed Center of gravity range envelope plotted by Aircraft Weight in y-axis against the Center of Gravity in x-axis.

This is used to find whether the actual Center of gravity is within the allowed range as defined by the balance graph.
John is absolutely right in whatever he had explained. Thanks John.. but we are done with that part.
The information am looking for is… on what basis the Balance Graph has been defined by the manufacturer? What is the fundamentals behind it… I mean how the lines forming the Balance Graph Polygon is arrived for different Aircraft Models and for Different Weights?

What is the different between car’s tire and aircraft’s tire ?

–> What kind of material is in the cars and aircraft’s tire?
–> (cars and aircraft’s tire), which one can stand higher temp ?
–>Which one can stand more friction?

If the aircraft’s tire can stand more friction and higher temperature, then what kind of material are needed to became lasting higher temperature and more friction in cars tire ??
