The scope in practice
B2 work ranges from troubleshooting an intermittent fault that only appears in flight, to loading a database update, to a full EWIS inspection, to embodying a modification under a Supplemental Type Certificate. It is diagnostic work: the fault message is a starting point, not an answer, and the value of an experienced B2 engineer is knowing which of five possible causes to test first.
As aircraft become more software-defined, the B2 scope keeps widening — connectivity installations, cabin systems, health monitoring and data loading are now routine parts of the job that barely existed two decades ago.
What gets you shortlisted
- Type ratings and the avionics suite you have worked on in anger
- ATA 22, 23, 24, 27, 31, 34 and 46 experience specifically
- Fault-finding depth versus remove-and-replace experience
- EWIS and Fuel Tank Safety training currency
- Experience with modification embodiment and STC work
Finding the right B2 role
JobAvion lets you record avionics experience at the level employers ask about — by system and ATA chapter, not just "avionics". That means an operator looking for someone who has genuinely chased autoflight faults on a specific type can find you, instead of both of you filtering through irrelevant matches.
