 DIMENSIONS AND AREAS - DESCRIPTION AND OPERATION
________________________________________________
 1.  General_______
 A.  This chapter contains the principle dimensions for the wing, ailerons, flaps, horizontal stabilizer, vertical stabilizer, and body. It shows some of the stations of the body, wing, vertical tail surfaces, engine nacelle. It also shows the location of the access doors and panels.
 2.  Reference Planes and Lines (Fig. 1)__________________________
 A.  General
 (1)  The airplane is divided into reference planes (stations), waterlines and buttock lines. These are measured in inches from fixed points of reference. This provides a means of quickly identifying the location of components, the center of gravity and the distribution of the weight.
 B.  Standard Abbreviations and Definitions
 (1)  Fuselage
 B STA,BS, or STA  Body (Fuselage) Station. This is a plane perpendicular to the fuselage centerline, It is located 159.00 inches forward of the nose.
 BBL or BL  Body (Fuselage) Buttock Line. This is a vertical plane parallel to the fuselage vertical centerline plane, BBL 0.00. located by its distance outboard from the fuselage centerline plane.
 BRP  Body (Fuselage) Reference Plane. This is a plane perpendicular to the BBL plane and passes through the top of the main deck floor beams (BWL 208.10).
 BWL or WL  Body (Fuselage) Waterline. This is a plane perpendicular to the BBL plane. It is located by its distance from a parallel imaginary plane (BWL 0.00). BWL 0.00 is 133.00 inches below the lowest fuselage surface.
