Circuit Breakers

Home / Blog / Circuit Breakers

Like any aircraft, the A320 has a big number of Circuit Breakers (C/B) that play a vital role in the safety of the electrical systems. Most of them are located in the back of the cockpit behind the pilots and the most important ones in the upper overhead above the pilots.

In our A320 Sim Software we have modelled the Circuit Breaker functionality as part of the aircraft electrical system. In total 173 C/B's have been implemented already, covering all of the main electrical devices and circuits. Dynamically as we evolve additional C/B's can be added very efficiently.

All these C/B's can be monitored and changed in state (cf. popped/reset) via the below shown Circuit Breaker page which is part of the Instructor Station web application. It features a handy filter option to select and show only the relevant C/B's you wish to see. It also allows to filter in specific properties, such as for example a specific C/B's identified by its name, location, FIN number, monitored or not, etc... And allows to filter also by state, to show for example only those C/B's that have popped.

Linked to the C/B's are of course also all the failures and warnings generated by the Flight Warning Computer (FWC) whenever the Instructor pops a C/B.

  1. Bonjour
    Merci de laisser à disposition toutes vos photos qui nous aident pour améliorer nos simulateurs d’A320 (car nous n’avons pas la possibilité d’avoir un vrai tronçon du cockpit par manque de place et aussi par manque d’argent)
    Votre projet est très audacieux et je suis très admiratif
    J’ai plus à apprendre de vous et n’ai malheureusement rien à vous apporter sauf…. mon soutien
    Nous sommes un petit groupe de 4 passionnés qui avons chacun des simus d’A320
    Vous avez pu faire votre projet en commun car vous etes proches alors que nous sommes assez loin les uns des autres (2 en ile de France, un à Rennes et un à Aix en Provence)
    Je regarde avec intéret vos travaux
    Merci à vous
    prenez bien soin de vous
    Philippe

    1. Hi Philippe,
      Thanks for your kind words.
      We will be posting updates on our progress.
      Also for you and your friends, take care!
