Appendix 1<br />
(a) The length of the cabin is 880 inches (FS 970 - FS 90).<br />
(b)<br />
The number of exit units in each zone is as follows: <br />
Zone A: 1.<strong>25</strong>; <br />
Zone B: 2.<strong>25</strong> (1.<strong>25</strong> + 1.0);<br />
Zone C: 2.<strong>25</strong> (1.0 + 1.<strong>25</strong>); <br />
Zone D: 1. <strong>25</strong>; <br />
Airplane total: 7.0. <br />
(c) Fuselage length factor= 1<strong>25</strong>.8 inches (880"/7.0).<br />

Nominal exit location: <br />
Exit 1: FS 277.2 (120 + (1<strong>25</strong>.8 x 1.<strong>25</strong>)); <br />
Exit 2: FS 565.2 {277.2 + (1<strong>25</strong>.8 x 2.<strong>25</strong>));<br />
Exit 3: FS 843.3 (565.2 + {1<strong>25</strong>.8 x 2.<strong>25</strong>)). <br />
Exit offsets, proposed versus nominal: <br />
Exit 1: Offset= 57.2" (277.2 - 220); <br />
Exit 2: Offset - 60.2" (560.2 - 500);<br />
Exit 3: Offset= 6.7" {850 - 843.3). <br />
Percent of exit offset:<br />
Exit 1: 6.5% (57.2/880 X 100%);<br />
Exit 2: 6.8% (60.2/880 x 100%);<br />
Exit 3: 0.8% (6.7/880 x 100%);<br />
All exits are offset less than 15 percent from the nominal<br />
locations and are acceptable.<br />
By inspection, no two exits are closer together than the fuselage<br />
length factor of 121.4 inches.<br />
