AMC to Appendix S, S25.40(c) Seats in Excess

S25.40(c) requires the installation of a placard, adjacent to each possible passenger boarding door, on aeroplanes which have a greater number of seats approved for occupancy during taxiing, take-off, and landing than the approved passenger seating configuration. It may be acceptable that the selection of which seats to occupy is at the operator’s/passenger’s discretion, or constraints may exist for instance due to the zonal limitations set by S25.1(a)(2), or the varying passenger seating configuration and/or direct-view limitations for an aeroplane with different, reconfigurable, cabin designs approved for private versus commercial transport operations. In such cases, the placard should indicate limitations of the allowable seating occupancy for taxiing, take-off, and landing, as appropriate, for each cabin zone, and not just for the aeroplane as a whole; moreover, different indications should be provided with reference to the different type of operations that may be performed (non-commercial/commercial). Additionally, if it is decided to help passengers in selecting acceptable seating locations by means of markings on a seat or seats, a local placard (text or symbolic), easily readable by a passenger approaching/seated on each such seat, should be provided. The placard should be of adequate size for easy readability.
