Avionics HMI developers depend on both in-house and COTS HMI tools in their day-to-day work.  Unfortunately, many of these solutions support only a narrow set of embedded computing platforms or do not meet the performance requirements that a program defines. This means that engineering choices can be limited for HMI software and hardware combinations at the initial design phase and that seemingly straightforward hardware upgrades during an aircraft's lifecycle can become problematic. Yannick Lefebvre explains how VAPS XT makes it easier to deploy avionics displays to multiple embedded platforms more quickly and efficiently.
