There are four rows of passenger seats, so this calculation depends on where the individual passengers sit. We have to make some assumptions about how passengers arrange themselves. Each row has two seats. The most popular seats are in row 2 because they are near the entrance and face forward. Once row 2 is filled, passengers usually take seats in row 1, facing their traveling companions. Row 3 is usually the next to fill up, even though it faces backward, because row 4 is a fold-down bench seat that is less comfortable than the armchairs in the forward rows. The following table gives the distance from the nose of the plane to each of the loading stations.</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table><table cellpadding="0" cellspacing="0" border="0" width="100%"><tr><td height="12"></td></tr><tr><td><table cellspacing="0" width="202" cellpadding="7"><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2"><i>Loading Station</i></font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2"><i>Distance from Nose (inches)</i></font></td></tr><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2">Crew seats</font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2">143</font></td></tr><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2">Row 1 seats</font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2">219</font></td></tr><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2">Row 2 seats</font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2">265</font></td></tr><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2">Row 3 seats</font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2">295</font></td></tr><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2">Row 4 seats</font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2">341</font></td></tr><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2">Closet</font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2">182</font></td></tr><tr><td valign="top"><font face="Times New Roman, Times, Serif" size="2">Baggage</font></td><td valign="top"><font face="Times New Roman, Times, Serif" size="2">386</font></td></tr></table></td></tr></table><br /><table border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="5"></td> <td colspan="3" height="12"></td> <td rowspan="5"></td></tr><tr><td colspan="3"></td></tr><tr><td></td> <td><font face="Times New Roman, Times, Serif" size="3"><img src="ae46be5b888444a52729068c4d55df9d.gif" border="0" alt="0435-02.gif" width="534" height="144" /></font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table><table border="0" cellspacing="0" cellpadding="0" width="100%"><tr><td rowspan="5"></td> <td colspan="3" height="12"></td> <td rowspan="5"></td></tr><tr><td colspan="3"></td></tr><tr><td></td> <td align="center"><font face="Times New Roman, Times, Serif" size="2">Figure8-4<br />A聽Passenger聽Moment聽Arm</font></td><td></td></tr><tr><td colspan="3"></td></tr><tr><td colspan="3" height="1"></td></tr></table></td></tr></table><p><font size="0"></font></p>聽 </td> </tr> <tr> <td align="left" width="30%" style="background: #EEF3E2"><a style="color: blue; font-size: 120%; font-weight: bold; text-decoration: none; font-family: verdana;" href="page_434.html">< previous page</a></td> <td align="center" width="40%" style="background: #EEF3E2"><strong style="color: #2F4F4F; font-size: 120%;">page_435</strong></td> <td align="right" width="30%" style="background: #EEF3E2"><a style="color: blue; font-size: 120%; font-weight: bold; text-decoration: none; font-family: verdana;" href="page_436.html">next page ></a></td> </tr> </table> </body> </html>⌨️ 快捷键说明
