Seat Tracks
If equipped, seat tracks are marked with station identication markings every
10 inches, starting at FS (Fuselage Station) 50.0. These markings will assist
the operator in quickly installing seats. Refer to the following example of how
to properly install a seat.
Example: To install a seat in Row 3 (FS 115.0), locate fuselage station
marking FS 110.0 and count 5 seat track notches AFT. Insert the seat lock
paw into FS 115.0 and move the seat 1/2 inch AFT and engage the seat track
lock. This is the location for the center of the seats track lock pin. For gures
and instructions regarding Passenger and Crew seat installation and removal,
refer to “Section 7” of this manual.
