The Boeing is an aircraft with a computer-controlled FCS, so it is reasonable to ask whether it is vulnerable. Avionics companies Aircraft instruments Computer file formats Cartography OpenTravel Alliance 6659 equity portfolio companies Carlyle Group companies Technology companies established in establishments in Maryland.

Please help improve this article by adding citations to reliable sources. When the pilots noted that the aircraft was not doing what they wanted, they would turn off the Flight Management System. An MitM spoofs one or more components transferring data on the bus.

Product Focus: Data Bus Test

On thefailures are isolated to the LRU level. Leivesley thinks one can can hijack the Flight Management System on a Boeing with a mobile phone. It follows the normal protocol but 6559 messages require a Cyclical Redundancy Check CRC be used as the last word in the message. They have to be — it is part of their certification requirements. Provides a 32 bit wide data bus, with a 50MBytes per second transfer rate. Archived from the original PDF on The bus is clocked and slotted, which means that data is transferred between components according to a global schedule in specific time slots; the bus time is given by a clock, of which values all bus users have to be aware.


Faults are reported through the central afinc computer function. These installations are mostly used for military aircraft, against which atinc might use such powerful radiators, but they are used by civilian aircraft too.

If you could take over the Flight Control System you would be able to make the airplane land or crash.

There has been a trend away from Level-3 component-level repair, Tremain notes. Bus Standards Organizations Info: It is not the certified SW running on an actual airplane, or on the actual aircraft HW, and has not been developed, analysed and tested to anywhere near the same exacting standards used for flight control software Design Assurance Level A, according to the RTCA DOB standard to which I believe the Boeing flight control system was certified.

MIL uses a Balanced Differential interface. Allison Transmission Diversified Machine, Inc. That must all be installed on a portable device, probably not a mobile phone, which you then use in flight.

The first widespread application of digital data bus technology in commercial aviation, ARINC has proved resilient over nearly 30 years of use. The Changing Landscape of Cybersecurity in Aviation. Then you need to figure out, not only the timing constraints, but what data you want to put on the bus. Leave a Reply Cancel reply You must be logged in to post a comment. Most avionics buses are serial in nature. By using this site, you agree to the Terms of Use and Privacy Policy.


ARINC has installed computer data networks in police cars and railroad cars and also maintains the standards for line-replaceable units. The Series comprises a set of aviation standards for aircraft, including fiber optics used in high-speed data buses.

Works in conjunction with the PI-Bus. From Wikipedia, the free encyclopedia. The message length is a 32 bit data word. Either there is one there already such as in one of the components sharing the bus or someone has to insert one a physical tap. CSDB uses a low-speed version of 12, bps or a high-speed version of 50k bps. It also requires a header, to be used as the first word in messages to certain sub-addresses. If you want an electronic system S to pick up and process signals from a radiating device such as a mobile phone, there has to be a receptive device attached to S.

The AIMS bus carries pure data between components who know what the data means. Naval Tactical Data System. Who knows what kinds of vulnerabilities it has and who cares?
