E. Wing
MAC Mean Aerodynamic Chord. The chord of a section of an imaginary airfoil on the
wing which would have vectors throughout the flight range identical to those of
the actual wing.
WCP Wing Chord Plane. A plane through the trailing and leading edges of the wing
airfoil.
WRP Wing Reference Plane. The outboard rear spar plane projected inboard.
W Sta Wing Station. A plane perpendicular to wing chord plane and plane of wing
reference plane (Outbd. RS), measured from intersection of extended leading
edge and wing buttock line 0.00.
WBL Wing Buttock Line. A plane perpendicular to wing chord plane and parallel to the
trace of a body centerline. It is measured from intersection of wing chord plane
and body buttock line 0.00.
FS or RS Wing Front Spar or Rear Spar. A principal spanwise transverse member of the
wing structure.
FSS or RSS Front or Rear Spar Station. A plane perpendicular to wing chord plane and plane
of the front or rear spar.
F. Nacelle
Nac BL Nacelle Buttock Line. A plane parallel to a wing buttock line. Nacelle buttock line
0.00 is equivalent to wing buttock line 191.00.
Nac WL Nacelle Waterline. A plane 1° 38' down from the wind chord plane, measured
32.250 inches down from the wing chord plane at nacelle station 63.47 the plane
is Nac WL 100.

Nac Sta Nacelle Station. Distance measured parallel to nacelle CL from a point 63.47 inches forward of the nacelle.
TR Sta Thrust Reverser Station. Distance measured parallel to thrust reverser centerline on a plane perpendicular to thrust reverser centerline from a point 92.92 inches forward of the thrust reverser.
TRWL Thrust Reverser Waterline. A plane 3° up from nacelle waterline. Thrust reverser waterline 100 intersects nacelle waterline 100 at thrust reverser station 96.47.
