The fuselage station distance is measured in which unit?

Explanation:
Fuselage station distance is measured in inches because it defines a precise location along the aircraft’s length from a fixed datum using small, easily readable increments. The station number represents that many inches aft of the reference point, allowing exact placement of frames, bulkheads, and other structures. For example, a fuselage station of 100 means 100 inches aft from the datum (about 8 feet 4 inches), which gives fine granularity needed for accurate alignment. Feet are too coarse for exact component placement, and metric units are not the standard in typical U.S. aviation maintenance drawings, so inches are used for these measurements.
