Collins Aerospace and Rapita present award winning paper at DASC 2024

 

The 43rd Digital Avionics Systems Conference (DASC) took place between the 29th September and 3rd October 2024 and we were delighted to present a paper titled Defining Quantifiable Measures for Data Coupling and Control Coupling with Collins Aerospace on Wednesday Oct 2nd, 2024.

Authored by Phillip Hamm and Chris Hubbs from Collins Aerospace and Andy Galloway and Daniel Wright from Rapita Systems, and presented by Chris, the award winning paper is a case study on a cooperative research project between Rapita Systems and Collins Aerospace. 
 

Using an upcoming tool being developed by Rapita, RapiCoupling, the two companies examined approaches for quantifying measurement of data coupling and control coupling (DC/CC). These verification analyses are mandated by DO-178C, but no guidance for quantification of these analyses has ever been published. The paper outlines the findings when measuring DC/CC on airborne flight display software and proposes quantifiable measures that could be used by the safety-critical software industry to assess the thoroughness of DC/CC analysis. 

The paper is available on IEEE Xplore and personal copies are available on request from Dr. Daniel Wright.
