Influence of Passenger Comfort Requirements on the Interior Layout of Long-Haul Aircraft

Abstract

The plane has become a convenient method of transportation. The main idea of aviation in the 21st century is the safety of passengers and crew, but the human is always inclined towards comfort. The structural and parametric analysis of the long-haul aircraft development made it possible to form the concept of the fuselage layout with capsule accommodation of passengers. By adding the third axis to the dimension of the aircraft expressed in take-off mass, it clearly showed the ultimate dimension of the aircraft, expressed by modern infrastructural constraints. The histogram of the distribution of flights between the largest airports in the world that can operate with long-haul aircraft was showed. The distribution of large airports was characterised by the demographic factor. The proposed variant of the capsule accommodation, designed for the Boeing 777-200LR, can be installed in other passenger airliners with a ceiling height of at least 2.1 m. Analysis of alternative options for the layout of the passenger compartment allows us to state: with a flight range of more than 8 hours, the flight is comfortable only in business or first classes. The proposed two-story capsule placement allows providing the layout with first-class seats in a given cabin.
