Exercise 3: Fuselage Top View

About the input variables:

• Number of Seats: The total number of seats to be included at the specifed effective pitch.
  
  
• Seat Pitch: The average longitudinal distance between seats. This drawing includes only a single seat pitch, while most aircraft will be divided into 2 or 3 classes with rather different seat pitch. Use an efgfective value that produces the correct cabin length.
  
  
• Nose Fineness: The ratio of nose length to maximum diameter. The nose section is defined as the section that extends from the forwardmost point on the aircraft to the maximum diameter section.
  
  
• Tailcone Fineness: The ratio of tailcone length to maximum diameter. The tailcone section is defined as the section the end of the constant section to the aft end of the fuselage.
  
  
• Forward Extra Space: The distance (in feet for now) from the start of the constant section to the first row of seats. This parameter is used to add extra space for galleys or closests, or may be made negative if seats extend into the "nose" section of the fuselage.
  
  
• Aft Extra Space: The distance (in feet for now) from the end of the constant section to the last row of seats. This parameter is used to add extra space for galleys or closests, or may be made negative if seats extend into the tailcone section of the fuselage.

The layout is based on the cross-section geometry specified in exercise 2.
