This paper provides an overview of three important emerging standards in modern Avionics - ARINC-664 Part 7 (AFDX), TTP and ARINC-653 - and addresses challenges and opportunities arising from their adoption. Beyond several potential benefits offered by these standards, additional effort should be expected by practitioners when system design requires, for instance, timing analysis for estimating data transmission jitter. This paper presents some of these design challenges and suggests new academic research opportunities for, for instance, extending current timing analysis methods for distributed systems.
