Case Study

Safety-Critical Avionics Display

We designed a safety-critical avionics display that provides control and display functionality for use with specific weather radar systems. Due to the requirement to deploy the radar unit in civilian contexts, changes were necessary for DO-178 certification of the device.

The development approach for the software upgrade had to cater for the legacy nature of the original development that lacked the necessary evidence for certification. New methods and processes needed to be employed to meet the requirements of the standard.
