Non-metallic seat structure such as shown in Figure 5 is not a panel. FIGURE

11、V. Flight attendant seats may be a single entity or several assemblies that are separately installed to perform their function (e.g., a wall mounted head rest).

19、IHS-,-,-SAE ARP6199 Page 14 of 30 5.5.4 Center Console A calculation of the orthogonally projected area of the center console is used to determine if it is traditional or non-traditional. Alternatively, other more detailed computational methods may be used to calculate the actual surface area of the
20、 exposed surfaces. The purpose of this calculation is to determine the overall size of the feature by surface area without respect to the materials used or the position of the seat cushions. The surface area is calculated using the sum of the projected areas on all sides of the item.Traditional cent
21、er consoles have a surface area of 1008 in2(6503 cm2) or less. Non-traditional consoles have a surface area greater than 1008 in2(6503 cm2) excluding traditional features mounted on the console described in this document.FIGURE 10 - CENTER CONSOLE AREA CALCULATIONIf the bottom of the center console

38、ten provided to or from seat features such as electrical components, mechanical actuator cables, moving parts (e.g., if the seat or seat features move by any type of actuation with respect to the base assembly), seat belt alignment shrouds, drip shields, and shrouds to protect from injuries such as
39、finger pinch.Shrouds may be located anywhere on the seat, provided they are sized as necessary to serve their intended protective function throughout all phases of flight.Material selection does not impact determination.Shrouds for electrical equipment are traditional provided they are sized as nece
40、ssary to allow for wire routing, connectors, bend radii and cooling. A traditional shroud shall not exceed 6 in (15 cm) greater than the electrical component on sides where connections are made or wires are routed and not exceed 2 in (5 cm) greater than the electrical component on sides that do not
41、have connectors or wire routing. Non-traditional: Primary purpose is to screen or hide items which are not specifically listed in the traditional category. Decorative shrouds are non-traditional. NOTE: Consoles are not shrouds although they may have shrouds incorporated into their design. FIGURE 15
