Aircraft that have fuselages including a series of frames spaced apart according to a frame pitch. The series of frames are covered by an aircraft skin to define an interior volume of the aircraft. The interior volume contains a series of rows of seats separated according to a seat pitch. The seat pitch may be indexed to the frame pitch such that seats are located between adjacent ones of the series of frames to permit a reduced-perimeter aircraft fuselage with substantially equal passenger comfort metrics. In some embodiments, in addition, a series of windows are located adjacent outboard seats of the series of rows of seats to permit ergonomically appropriate viewing through the series of windows by passengers seated in the outboard seats.

The aircraft of claim 1, wherein the interior volume of the aircraft comprises a passenger cabin, the passenger cabin comprising interior panels, the interior panels attached to the series of frames and sculpted to encroach outboard into said inter-frame space. 3. The aircraft of claim 1, wherein the outboard seats comprise outboard armrests, the outboard armrests encroaching at least partially outboard into the inter-frame space. 4. The aircraft of claim 1, wherein each frame is located between adjacent ones of the series of seats at specific longitudinal locations, each frame at said specific longitudinal location with sufficient longitudinal displacement from the longitudinal location of a widest portion of the head of an occupant seated at a seat reference point when said occupant is in a posture with torso and head bent fully forward from the seat reference point with 10 degrees of outboard yaw, said seat reference point comprising a longitudinal location of a point on the seat where an occupant settles into the seat and takes into account seat cushion deformation, said occupant seated with seat belt properly positioned and secured in an outboard seat immediately behind said frame, wherein when said occupant is in a posture with torso and head bent fully forward from said seat reference point with 10 degrees of outboard yaw, said sufficient longitudinal displacement ensures a nonzero longitudinal clearance between an outboard side of said widest portion of the head and said frame. 5. The aircraft of claim 3, wherein the outboard armrests encroach into at least about 50% of a width of the inter-frame space. 6. The aircraft of claim 1, further comprising windows in the fuselage, the windows located at a window pitch relative to each other. 7. The aircraft of claim 6, wherein the window pitch is substantially equal to the seat pitch. 8. The aircraft of claim 6, wherein the window pitch is selected to ensure ergonomically appropriate viewing through the windows by passengers seated in outboard seats. 9. The aircraft of claim 1, wherein the fuselage comprises a first composite material. 10. The aircraft of claim 1, wherein the series of rows of seats comprise at least three seating modules with an aisle inboard of each of outboard ones of the three seating modules. 11. The aircraft of claim 1, wherein the frame pitch is about 28 to about 38 inches and the seat pitch is about 28 to about 38 inches. 12. A reduced fuselage perimeter aircraft comprising: a composite fuselage comprising a series of composite frames, the series of composite frames spaced apart according to a frame pitch, the series of composite frames covered by a composite aircraft skin to define an interior volume of the reduced fuselage perimeter aircraft; a series of rows of seats located in a passenger cabin disposed within the interior volume of the reduced fuselage perimeter aircraft, the series of rows of seats comprising outboard seats comprising outboard armrests, the series of rows of seats separated according to a seat pitch, the seat pitch indexed to the frame pitch such that seats are located between frames and the outboard armrests on the outboard seats encroach at least partially into an inter-frame space; and a series of windows in at least a portion of the passenger cabin, the series of windows located adjacent outboard seats of the series of rows of seats to permit ergonomically appropriate viewing through the series of windows by passengers seated in the outboard seats; wherein said seat pitch indexed to the frame pitch provides a reduction in an aircraft perimeter by said encroachment into an inter-frame space, said encroachment while maintaining seat width, lateral seat spacing, and aisle width of said rows of seats. 13. The aircraft of claim 12, wherein each frame is located between adjacent ones of the series of seats at specific longitudinal locations, each frame at said specific longitudinal location with sufficient longitudinal displacement from the longitudinal location of a widest portion of the head of an occupant seated at a seat reference point when said occupant is in a posture with torso and head bent fully forward from the seat reference point with 10 degrees of outboard yaw, said seat reference point comprising a longitudinal location of a point on the seat where an occupant settles into the seat and takes into account seat cushion deformation, said occupant seated with seat belt properly positioned and secured in an outboard seat immediately behind said frame, wherein when said occupant is in a posture with torso and head bent fully forward from said seat reference point with 10 degrees of outboard yaw, said sufficient longitudinal displacement ensures a nonzero longitudinal clearance between an outboard side of said widest portion of the head and said frame. 14. The aircraft of claim 12, wherein the outboard armrests encroach into at least about 50% of a width of the inter-frame space. 15. The aircraft of claim 12, wherein sides of the passenger cabin comprise interior panels, the interior panels sculpted to encroach into the inter-frame space. 16. The aircraft of claim 12, wherein, in at least a portion of the passenger cabin, the frame pitch equals the seat pitch. 17. The aircraft of claim 16, wherein the frame pitch is between about 28 to about 38 inches. 18. The aircraft of claim 16, wherein in at least a portion of the passenger cabin the series of windows are spaced apart by a window pitch, and the window pitch substantially equals the seat pitch. 19. The aircraft of claim 12, wherein the frame pitch is about 28 to about 38 inches and the seat pitch is about 28 to about 38 inches. 20. A reduced fuselage perimeter aircraft comprising; a composite fuselage comprising a series of composite frames, the series of composite frames spaced apart according to a frame pitch, the series of composite frames covered a composite aircraft skin to define an interior volume of the aircraft; and a series of rows of seats spaced apart according to a seat pitch and located in a passenger cabin, the passenger cabin disposed within the interior volume of the aircraft, the series of rows of seats comprising outboard seats having outboard armrests, the seat pitch indexed to the frame pitch such that outboard seats are located between adjacent frames with the outboard armrests encroaching into an inter-frame space; and, wherein each frame is located between adjacent ones of the series of seats at specific longitudinal locations, each frame at said specific longitudinal location with sufficient longitudinal displacement from the longitudinal location of a widest portion of the head of an occupant seated at a seat reference point when said occupant is in a posture with torso and head bent fully forward from the seat reference point with 10 degrees of outboard yaw, Said seat reference point comprising a longitudinal location of a point on the seat where an occupant settles into the seat and takes into account seat cushion deformation, said occupant seated with seat belt properly positioned and secured in an outboard seat immediately behind said frame, wherein when said occupant is in a posture with torso and head bent fully forward from said seat reference point with 10 degrees of outboard yaw, said sufficient longitudinal displacement ensures a nonzero longitudinal clearance between an outboard side of said widest portion of the head and said frame; wherein said seat pitch indexed to the frame pitch provides a reduction in an aircraft perimeter by said encroachment into an inter-frame space, said encroachment while maintaining seat width, lateral seat spacing, and aisle width of said rows of seats. 21.
