Which lines are used on aircraft drawings to show alternate positions?

Medium width dashed lines are specifically used on aircraft drawings to indicate alternate positions. This is a standardized practice in technical drawings, including aircraft schematics, where different configurations or offsets of components need to be depicted clearly. The use of dashed lines helps differentiate these alternate positions from other types of lines, such as solid or thicker lines, which are used to show more permanent or fixed elements. This distinction is crucial for mechanics and engineers when interpreting designs, ensuring that they accurately understand how components may be adjusted or repositioned during assembly or maintenance.
