How is the brake reference line calculated?

The brake reference line is a critical measurement in aircraft maintenance, specifically relating to the position of components in the aircraft structure. The correct calculation of the brake reference line often involves adding the measurement of the brake target line distance (BTLD) with the radius (R) of the component or structure being considered.

The equation indicates that the brake reference line is derived from the baseline distance to the brake target line, alongside the radius that extends from this point. This is essential for ensuring that various parts of the aircraft, such as control surfaces and landing gear components, are aligned and functioning correctly.

By adding the radius to the brake target line distance, you ensure that the overall distance measured for alignment takes into account the curvature or offset necessary for the components to function optimally. Hence, this calculation is crucial for maintaining operational safety and performance standards in aircraft structural integrity.
