Abstract: A cabin segment for a vehicle includes two or more parking spaces, arranged side by side and separated from each other by at least one intermediate wall, for accommodating serving trolleys, and furthermore a vehicle attendant seat which on one side is held on one of the at least one intermediate walls so as to be pivotable on an axis. The vehicle attendant seat is pivotable to an in-use position and to an out-of-the-way position.

Abstract: An engine is mounted on a structure by an intermediate structure assembled by flanges, to the structure and to the engine, where a rigid structure connects the flanges. This arrangement enables design of the structure to be simplified while allowing a substantial overhang when it is sought to mount the engine by the plane of its center of gravity, while being obliged to move the mounting structure away from it. The intermediate structure is resistant to forces resulting from the overhang, and also allows assemblies that are favorable to a balanced transmission of forces to the structure and a satisfactory ability to filter vibrations.

The ice separator includes, but is not limited to an inflow aperture with a downstream trapping pocket at the airflow deflection surface, in which trapping pocket ice particles from an airflow flowing onto the ice separator are trapped due to their inertial forces. In this way with simple means an effective device for removing ice particles from airflow may be achieved.
