  • BSI Flex 1903 v2:2024-06 community preview

    This is an interactive version 2 of BSI Flex 1903. The aim of the standard is to create a lexicon of standard terms and acronyms used in this sector. Please note, content is still undergoing internal review and there may be minor changes at full publication.

    We welcome your engagement and comments on this version to help inform the development of the standard. We would also welcome general feedback including what terms could be considered for future versions and these can be made through our dedicated feedback page .

  • Definition

    flight control system with signalling by optical fibres

     

    NOTE 1 In a fly-by-light system, the electrical wiring used in fly-by-wire (3.1.75) systems is replaced with optical fibres, offering advantages such as increased data transmission speed, electromagnetic interference (EMI) (3.1.65) immunity, and potentially reduced weight.

    NOTE 2 On fly-by-light aircraft, flight controls are typically implemented according to complex control laws and logics.
