  Mobile devices are becoming part of modern digital avionics. Mobile devices
can be applied to a range of scenarios, from Electronic Flight Bags to
maintenance platforms, in order to manage and configure flight information,
configure avionics networks or perform maintenance tasks (including offloading
flight logs). It can be argued that recent developments show an increased use
of personal mobile devices playing an integral part in the digital avionics
industry. In this paper, we look into different proposals for integrating
mobile devices with various avionics networks -- either as part of the Bring
Your Own Device (BYOD) or Corporate Owned Personally Enabled (COPE) paradigms.
Furthermore, we will evaluate the security and trust challenges presented by
these devices in their respective domains. This analysis will also include the
issues related to communication between the mobile device and the aircraft
network via either wired or wireless channels. Finally, the paper puts forward
a set of guidelines with regards to the security and trust issues that might be
crucial when enabling mobile devices to be part of aircraft networks.
