US 8,783,613 B2 · Observation port and a helicopter cabin

Abstract

An observation port (4) in a primary structure (13) of a helicopter cabin (0) is disclosed, which is arranged between a pilot's seat (2) and a co-pilot's seat (3). The observation port (4) is delimited from the interior by an inner screen (15), and from the atmosphere by an outer screen (16), wherein the pilot can observe the space underneath the helicopter cabin (0) through the observation port (4). As a result of the configuration of the observation port (4) the pilot can assume an ergonomic and relaxed seating position at any time, even when he is executing flights with suspended loads. By means of the observation port (4) and the windows (15, 16), which extend laterally between the two pilots' seats (2, 3), a novel unrestricted vertical visual frame of reference onto the suspended load is achieved, wherein the length of the load cable has practically no influence.
