This Service Bulletin provides a software upgrade to the MLB700 Satellite Datalink Receiver. This new software reduces MLB700 initialization time and nuisance messaging. Please contact your authorized Avidyne Service Center to have this upgrade performed on your system.
This Service Bulletin provides important safety information concerning aircraft equipped with certain Avidyne EXP5000 Primary Flight Displays (PFDs) that may display incorrect altitude and airspeed information.
As noted in the SB, we expect it to be accepted as a final action with respect to AD XXXX, which is currently under revision by the FAA. While we encourage compliance with the SB at the present time, owners should note that a signoff will be required within the compliance interval specified by the final AD. This signoff can be based on a previously conducted test and, if necessary, service in compliance with the SB, as long as it has been logged at the time it is performed.
This Service Bulletin provides information on how to prevent the loss of function on the Avidyne Multi-
Functional Display (MFD) when an abnormally large number of storm cells are received from the MLB700
receiver.
This Service Bulletin provides information on known incompatibilities between Garmin 400W/500W series navigators and Avidyne Primary Flight Displays. It includes mandatory operational limitations for aircraft with certain combinations of equipment and recommends against new or updated installations in affected configurations.
