An Embraer EMB-545 operated by Air Sprint Inc., was conducting flight ASP816 from Lexington (KLEX), KY USA to Calgary (CYYC), AB. Enroute, approximately 75 minutes from the destination, the Crew Alerting System (CAS) indicated an AVNX LH DU FAULT, and an AP FAULT.
All navigation sources were lost on the captain's side along with multiple flags on the PFD and multiple failures associated with the multifunction keyboard pad. The #1 FMS failed, and the auto throttles disengaged. Control was transferred to the first officer and the QRH was actioned for the CAS items. Control of the pressurization was lost and the crew expedited descent while declaring a PAN PAN. ARFF was declined and the crew planned a shallow descent. A normal landing was carried out using the co-pilot instruments for reference.
Maintenance rebooted the avionics system and all system resumed normal operation.
