Abstract: This relates to a metallic primary-structure element for an aircraft with a recess, a ground connection that is attached in the recess, and connected in an electrically conductive manner to the metallic primary-structure element, and is designed to receive a connector. This further relates to a method for potential equalization in an aircraft, wherein potential equalization between electrical or electronic devices on board the aircraft and the aircraft itself is produced.

Abstract: A holding device for a mounting part installed inside an aircraft fuselage includes an anchor plate configured to attach the holding device to a support rail of the aircraft fuselage and including at least one engagement section. The holding device further includes a holder module separably connected to the anchor plate and configured to fix the mounting part to the aircraft fuselage and having a hook section configured to positively engage the at least one engagement section so as to fasten the holder module to the anchor plate, and at least two clamping blocks disposed on the holder module.

Abstract: A device for bridging a cable harness between two aircraft structure elements of an aircraft includes an elongated connecting rod having a plurality of radial snap-in holes and configured to bridge a space between the two aircraft structure elements and affix to at least one of the two aircraft structure elements. The device also includes a cable guiding element having at least one receiving section for receiving the cable harness and at least one attachment section circumferentially surrounding the connecting rod, the attachment section having a resiliently held radially directed locking pin, wherein the locking pin corresponds to one of the plurality of the radial snap-in holes so as to form a clip connection and a positive locking engagement between the at least one attachment section and the connecting rod.

Abstract: An air intake for an aircraft forms a first airflow channel (8) for feeding fresh air into the aircraft, and a second airflow channel (2) for feeding cooling air to an auxiliary power unit (AP). These first and second airflow channels are so positioned relative to each other that respective channel inlets or flow cross-sectional areas can be opened and closed by a single seesaw rocker (4) which is journaled or hinged between its ends to the aircraft body in such a position that one end (4A) of the seesaw rocker (4) can close the first channel (2) while the other rocker end (4B) simultaneously closes the second channel (8). The seesaw rocker (4) is driven by a motor responsive to the operation of the auxiliary power unit. When the auxiliary power unit operates, both channels (2, 8) are open. When the auxiliary power unit does not operate both channels (2, 8) are closed.
