Summary

Introduction

FLOSS & Open Source Communities

Introducing Open-DO

Why an Open Initiative for DO-178?

Keys to Success

Annex: Description of the mentioned projects

Which Arinc 653 OS will be around in 15 years?

Commercial Solutions- WRS, Sysgo, LynuxWorks, GHS, DDCI

Private Solutions maintained internally by Avionics companies- At least 3 in Europe & 1 in the US

Experimental- RTEMS + 653 interface

Introduction

Any lessons from what happened in the Unix world?

FLOSS License

Free to use… for ever

Free to look at sources

Free to change

Free to redistribute

Open Source Communities

Significant technologies are successfully managed by such communities:

- The Linux Kernel

- Eclipse

- GCC

- RTEMS

- Mono

- Python

…

For more than 20 years now

Open Source Communities

The GCC example… and many more

• Contributors: from individuals to corporations

• Sharing technology not products

Roles in Open Source Communities

Active participants

Short term cost increase- Learning curve

- Working in an open environment

- Contributing back

Long term cost decrease by- Sharing Resources

- Solving a common problem

- Avoiding solving already solved problems

Initiators & regulators

Passive Users• Benefit from the work of others

• Can’t customize to their own needs

• Help spread the technology

• What about the DO-178 community?

• Is there a need for openness & cooperation?

• Potential for community growth?

• AVSI (Aerospace Vehicle Systems Institute)

• Certify Together

• This comittee• military

• space, automotive, …

Why an open initiative for the DO-178 world?

Why Open-DO?

Educational materials for clarifying intent

Experimental test-bed for annexes

A support to the DO-178C effort

Provides a shared infrastructure- For long term investment

- For long term cost reduction

Allows some level of cooperation with competitors

Lower training costs (especially for subcontractors)

Avionics industrial community

Why Open-DO?

Lower training costs for DERs

Vehicle for clarifying specific issues

Help sharing or practices between authorities

Certification authorities

Why Open-DO?

Offers an ideal showcase for their open technologies

Tool sharing makes it easier to provide a complete supported solution

Creates and ecosystem where everyone can meet potential

customers and partners

Tool providers

Why Open-DO?

Balance

- Europe vs US

- Boeing vs Airbus

- Authorities vs Industry

Find key participants for critical mass

- Certification authorities

- Major Aeronautics players

- Established tool providers

- Academics

Attract public funds for bootstrap

Find appropriate governance rules
