What is BS EN 4723 - Methods for comfort and living space criteria for aircraft passenger seats about?
BS EN 4723 is a standard covering methods for comfort and living space criteria for aircraft passenger seats, ensuring comfort and safety in aerospace applications.
BS EN 4723 specifies requirements and measurement methods for assessing passenger living space and comfort. It aims to improve the passenger comfort quality of aircraft cabins and provide measurement methods to compare cabin seat layouts and seats.
The aim of BS EN 4723 is to give advice to designers to include methods of human-centred design into the design of aircraft seats.
BS EN 4723 has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN).
