Station
numbers
Station points or station markings are a location system for aircraft.
Some
manufacturers, particularly in the aircraft industry, use station points to
locate parts or assemblies. The centerline at the center of the part or
assembly is designated by a zero. Incrementally numbered ribs to the left
and right of the centerline serve as station markings to locate details. Station
points appear on the actual drawing of the part or assembly.
Figure 1-42 illustrates the use of station points in aircraft drawings.
