Abstract: A removable barrier and an aircraft including such a removable barrier. The barrier including a panel configured to block at least partly an opening delimited by a frame, a plurality of straps each connected to the panel and each having first and second ends, for each strap, a first connection configured to connect the first end of the strap and a first edge of the frame at least temporarily, a second connection configured to connect the second end of the strap and a second edge of the frame at least temporarily, at least one folded overlength at the level of at least one of the first and second ends of the strap, at least one breakable connection keeping the overlength folded.

Abstract: A reusable seal including an antenna, an opening sensor to sense the opening of a volume to be monitored and an electronic device coupled to the antenna and configured to communicate with a reader via the antenna. The electronic device is supplied with power only by the antenna when a reader is proximate to the antenna. The seal has a memory that may assume an active state or an inactive state. The seal is configured such that the memory may be activated only by the electronic device when the device is supplied with power to store an intact seal state in the memory, and the memory may be deactivated at any time when the opening sensor is actuated to store a non-intact seal state in the memory. The seal is configured to respond to a request from a reader regarding its state according to the memory state.

Abstract: A method for determining a characteristic associated with a portion of a path of an aircraft includes the following steps, implemented by a processing unit of a computer: acquiring timestamped information relating to points of the path of the aircraft; selecting an interval of successive points of the path, corresponding to the portion of the path; selecting a first predetermined number of subsets of points belonging to the interval of points; determining a value of the characteristic for each subset of points; and determining a value of the characteristic for the interval of points, based on the values of the characteristic that are determined for each subset of points.

Abstract: An aircraft includes comprises toilet that includes a protection device configured to contain effects of a malicious device, in order to protect both a fuselage of the aircraft and passengers of the aircraft against the effects of the malicious device.

Abstract: A method for collecting flight data from aircraft. Each aircraft in a set of collecting aircraft collects information of ADS-B type received from other aircraft and associates contextual information with the received information of ADS-B type. Additionally, each aircraft in the set of collecting aircraft transmits the received information of ADS-B type, as well as the associated contextual information, to a common server. The common server receives and stores the information transmitted by the various aircraft in the set of collecting aircraft. The stored information is filtered so as to exclude information of ADS-B type which is incoherent taking into account contextual information. At least some of the filtered information is transmitted to a user.
