Abstract:
A step (10) comprising a portable support assembly (30) having a vertical body (40) carrying a tread (31). The step includes at least two pegs (20) fastened to a fuselage (2). The body (40) includes one fastener orifice (50) per peg (20), said body (40) being carried by said pegs (20). The step includes at least one locking system (60) carried by said body (40) for automatically locking the position of at least one peg (20) in a fastener orifice (50), and manual unlocking means (86) connected to the locking system (60) for enabling the body (40) to be manually separated from the pegs (20).
Abstract:
A rotorcraft fitted with means for mounting at least one front avionics rack (3, 3′) and man-machine interface instruments (2) on board a fuselage structure (4). A mounting structure (1) comprises a slotted body forming compartments for receiving interface instruments (2), the avionics rack (3, 3′), and a unitary cabling assembly (12) suitable for incorporating as a block with the mounting structure (1). The mounting structure (1) is installed as a block on the fuselage structure (4) after its functioning has been verified. The unitary cabling assembly (12) may also include separation connectors (14) segregating communications of the front avionics rack (3, 3′) respectively with remote computers (5) by means of a primary communications bus of the multiplexed, unidirectional, or bidirectional type, and with ancillary equipment (6) and/or with on-board instruments (7) by means of a secondary fieldbus.
