Abstract: The invention relates to a cabin air inlet module (16). The cabin air inlet module (16) comprises a streaming channel body (8). The streaming channel body (8) comprises at least one wall which limits a streaming channel wherein incoming air (5) is supplied to a zone (2) of a cabin (3). The cabin air inlet module (16) comprises an electric heating element (9) which is used for heating the incoming air (5). According to the invention it is proposed that the electric heating element (9) is embodied as a two-dimensional heating element (in particular as a heating paper, a heating web, a heating foil or a heating varnish). The two-dimensional heating element extends along a wall of the streaming channel body (8). The inventive cabin air inlet module (16) is arranged upstream with a small distance (25) from an inlet opening (6) into the zone (2) of the cabin (3). The inventive cabin air inlet module (16) is used for a tempering zones (2) of a cabin (3) of an airplane according to the needs.

Abstract: A method for displaying a noise level (Lfar field) of a rotary-wing aircraft (10) and system there for, the method comprising the following steps: (a) detecting a torque (Mengine) in a drive train of the rotary-wing aircraft (10), (b) detecting of a forward speed (Vforward) of the rotary-wing aircraft (10), (c) determining a noise level of the rotary-wing aircraft (10) from the torque (Mengine) or the torque (Mengine) and the forward speed (Vforward), and (d) providing an indication of the noise level in a cockpit (20) of the rotary-wing aircraft (10).
