  "PageContent": "introduction to open software and open hardware(Open source avionics: Last updated by Benjamin on August 28, 2024)What is avionics?Avionics includes all an aircraft’s electronic and computer systems, from radio communication devices to engine monitoring systems. It also includes navigation systems, autopilot, anti-collision systems, flight parameters monitoring, sensor and actuator management, etc.In certified aircraft, all these systems are TSO’ed, designed, installed, and maintained by authorized professionals. The regulations are more flexible for homebuilt, experimental, and ultralight aircraft. One of the basic rules is the individual responsibility of the owner and the pilot. In no way is the latter exempted from the obligation to respect the rules of art and airworthiness monitoring. The owner/pilot is responsible for maintenance and continuing airworthiness and may thus intervene in most avionics systems. However, systems that possibly affect the safety of controlled airspace may remain monitored by the authorities (VHF and transponder, for example).Who is this open-source avionics website for?This site is intended for all owners, pilots, and amateur builders of non-certified aircraft. Especially those who are passionate about electronics and computer sciences. For those who wish to know more and share about open source avionics systems. For those who dream about designing, building, programming, installing, and operating their own devices: EFIS, EMS, and more. Under their responsibility. The only prerequisite is to have a soldering iron!How is it possible?This challenge was made possible thanks to the advent of high-performance microcontrollers that are easy for enthusiasts to master. Therefore, the only limit is passion! The Arduino project dates back to 2005 and made the world of microcontrollers easily accessible to non-professionals. At an insignificant cost, it allows complex developments and efficient devices combining sensors and actuators. Such as a robot, a home automation station, or… an artificial horizon!We will see (here) that Arduino boards are not the only ones on the market nor the most adapted to avionics needs. Nevertheless, their fame and their anteriority justified the domain name of this site: avionicsduino.Website goalsThe primary purpose of this site is to present the circuits and software for avionics systems that meet these specifications:Anyone can build and program them, starting from elementary basics.They are economical; their price must be much lower than that of equivalent commercial systems.These systems genuinely work; they have been flight-tested.This Website also aims to present more general articles on microcontrollers, tests, techniques, projects in progress, etc., always in the field of avionics and aviation.The concept of open-source avionics makes it possible to build highly personalized, high-performance systems that are much more economical than certified ones while learning a lot and having fun! The aircraft airworthiness manager ensures its achievements do not compromise safety or contravene regulations. French regulations can be consulted here. US and UK regulations are not so different for uncertified ultralight, homebuilt, or experimental aircraft. A manufacturer’s authorization may be required to modify its equipment for Light Sport aircraft.It is necessary to keep in mind that these systems are to be produced yourself; they should not be used during flight as if they were certified; their builder must extensively test them to evaluate their performance; they must always be used in addition to the mandatory instruments; they must not lead to a significant modification of the aircraft which could require approval from the authorities. There is no guarantee of the accuracy and reliability of these systems other than that evaluated by the builder under his responsibility. Of course, IMC, IFR, and night VFR are excluded! Only daytime VFR, where the failure of these systems does not compromise safety, thanks to appropriate backup instruments.This site’s information, software, and hardware are subject to a disclaimer and a copyright notice.AuthorsThe authors are neither aeronautical professionals nor electronics or software engineers. They are amateur builders of their planes (three MCR Sportster) and are driven by the same passion for electronics and computers.MCR Sportster",
