Note 1

An aisle is the area that provides unobstructed access throughout the passenger service vehicle from each doorway used for passenger entry and exit to the footroom of each passenger seating position and includes aisle steps and internal ramps.

* The minimum aisle height dimension in Table 7-4-2 (other than for standing passengers) must be applied to the entire aisle throughout the passenger compartment.

In the case where there are aisle step(s) in front of a seat at the rear of the aisle, foot room for that seat may be considered to extend to the edge of the rearmost riser leading to that seat or the front edge of the seat immediately in front of the rear seat, whichever is the lesser distance (see “Distance ‘A’” in Figure 7-4-3).

While the height above the foot room does not have a minimum requirement, it must still allow easy access to the seating positions.

The aisle length is the longest aisle in a compartment measured as follows if only one doorway:

a) the front edge of the doorway to the front edge of the front seat serviced by that aisle, or

b) the rear edge of the doorway to the front edge of the rearmost seat serviced by that aisle (above).

 
Aisle length measurement – more than one doorway opening into aisle

aisle lingth measurement - more than 1 aisle

The aisle length is the longest aisle in a compartment measured as follows if more than one door opens into the aisle, measured from:

a) the front edge of the front doorway to the front edge of the front seat serviced by that aisle, or

b) the rear edge of the rearmost doorway to the front edge of the rearmost seat serviced by that aisle, or

c) the point halfway between the front edge of the rearmost doorway to the rear edge of the front doorway (above).
