PASSENGER SEAT DIMENSIONS

Minimum Seat Pitch


Minimum Seat Pitch

• CAP747 -require the minimum distance between the seat cushion and any other seat back or fixed structure is 26” (66cm) dimension “A”. (next slide)

• - Dimension B must be a minimum of 7” (18cm)

• distance the passengers leg has to move from

• thigh support to seat back.

• - vertical separation between seats must

• not less than 3” (7.5cm) includes the seat

• in the reclined position.

PASSENGER SEAT


Minimum Seat Pitch

# Emergency exits (over-wing small and slightly

larger exits) the clearance has to be increased,

vertical separation between seats at these locations

must not reduce below 10” (25.5cm).

# To prevent head injury of passengers as they

impact their head on the seat in front under heavy

braking the row of seat after emergency exits must

be able to break forward.

PASSENGER SEAT



• - Over-wing emergency exit points, in emergency,

people will climb over the seats to get out and if

seats were to fold a crush would hamper the

evacuation, so these seat backs will not fold

forward.

• - CS25 specifies aisle width which will depend on

seat numbers. Maximum numbers of seats

abreast in a single aisle aircraft is 3.

PASSENGER SEAT


• The minimum number and size is specified in CS25 and are related to the seating capacity of the aircraft:

Passenger seats Number

Colour Change

- by dyed (to match the cabin decor) permission

- must be obtained from the belt manufacturer.



Proof Testing

• - After repair, specified in the maintenance schedule, part of the belt using material in a load bearing capacity should be proof tested to a specific load.

• - but in general test load should be ½ of the certified strength of the member under test.

• - The release should work at 1.5g.



Storage

• - belts and harnesses should be stored in clean, dry conditions at normal room temperature and away from direct sunlight.
