The mission seat is mounted on a carriage floor and attached to the cabin floor by four corner attachments
that engage rails in the cabin floor. A locking pin at each corner attachment locks the seat to the floor rails to
prevent the seat coming out of the floor track during fore and aft movement.
Four retaining spigots provide extra security in the floor track.
For removal and installation of the seat and components, refer to para 2. thru para 5.

- To change the aircraft seating configuration.
