The seats meet all the requirements of AN64 and FAR 25.562 and are installed in the aircraft in the usual way, with conventional seat studs that mate with unmodified seat tracks.

Interface loads for this seat are slightly lower than conventional seats, due to the altered position of the centre of gravity when compared to conventional seats.

Studies have determined that oxygen drop-out and overhead lighting/crew-call/gasper reach are all acceptable for the maximum range of body sizes without any modification to the aircraft.

Toilets and Galleys
Introducing tri-angular toilets optimises the use of space at the front and rear of each column of seats, but this is not a requirement and is usually only considered for new aircraft deliveries.
