The process of aircraft design is a complex combination of numerous disciplines which have to be blended together to yield the optimum configuration to meet a given requirement.

Seating Arrangement

The following points should be considered:

Should be arranged such that the passengers need to move as little as possible.

As far as possible the passenger seats and provision for freight and baggage should be equally disposed about the nominal centre of gravity position.

If a seat directly faces a bulkhead additional space is required together with protection in the event of a crash.One toilet for each 50 passengersOverhead lockers Headroom and aisles width

Cabin widthThe internal width of the cabin is determined by a combination of:

Width of individual seats and the number of them across the cabin

• Width of individual seats and the number of them across the cabin. Seats are usually used in sets of two to four. No passenger should have to cross more than two others to reach an aisle. Individual economy class seats are just over 0.5 m wide, but there are variations. Business and first class seats are wider.

• Aisle width should be at least 0.4 m with 0.5 m desirable in economy arrangements and 0.6 m or more in first class. Up to six seats across, in two pairs of three, can be used with a single aisle. Theoretically up to twelve seats across can be used with two aisles, although a maximum of eleven is more usual.

Aisle width

• The internal width of the cabin for economy seating is approximately given by the relationship (0.5p + 0.55a), where p is the number of seats across the cabin and a is the umber of aisles. Typical first class seating layout requires between 125 and 140% of the width of economy seating.

Cabin length

The length of the cabin is determined by:

The seat pitch, The number of rows Provision of galleys, toilets

• Seat pitch which varies from as low as an uncomfortable 0.7 m for high density short flights to above 1 m in first class accommodation. The actual pitch used is a decision made by the operator but the designer must make acceptable provision when proposing the capacity of a given design. As a guide the economy seating pitch on long haul flights is typically about 0.83 to 0.85 m with business class at about 1.0 m and first class up to 1.5 m.

where P is the total number of passengers in that unit of accommodationg is the number of galleys along the lengthp is the number of seats across the cabin widths is the seat pitch (m)t is the number of toilets along the lengthw is the number of cross aisles

• A typical galleyfloor area of some 2 m by 0.65 m may be assumed for initial purposes. Location of the 0.65 m dimension along the length of the cabin enables a galley to be accommodated within a typical seat pitch or opposite an entrance door.

• Toilets have a typical floor area of 1 m 2, but it is acceptable to reduce the width to about 0.7 m with a corresponding increase in length. See paragraph.

• The total length of cabin in any given unit of accommodation is approximately:
