SOFTWARE UPDATES
With very few exceptions, all software inside the IFDs is capable
of being updated via the USB connections as well. This means
the IFD does not need to be returned to the factory for any future
software updates. The Avidyne position is that any shop that
holds a repair station certificate, an A&P, or an Experimental
Aircraft owner with log book signoff authority can perform the
update. The person performing the update must follow the
provided Service Bulletin explicitly and mail/fax/email back in the
completed update sheet that is part of the Service Bulletin but
Avidyne does not restrict this to just Avidyne Service Centers.
