PLEASE READ THIS BULLETIN IN ITS ENTIRETY BEFORE CONTACTING DYNON AVIONICS
Original Bulletin: March 29, 2016 (superscedes previous bulletin)
Some Dynon Avionics pilots have experienced unresponsive SkyView displays in flight after their system has been upgraded to version 188.8.131.5286.This software issue only affects earlier SkyView displays. Even though only certain hardware is affected, this is fundamentally a software issue. This issue has been driven to root cause, and a fix is available via a software update to version 14.1 or later. In other words, displays identified in the “Applicability and Affected Equipment” section below are not inherently defective from a hardware perspective. They do, however, need a software update.
Only the following SkyView displays are affected:
The following equipment is NOT affected by this service bulletin, regardless of software version installed:
If you have an unaffected display, Dynon still recommends updating from 14.0.x to 14.1 due to the other improvements in the software.
Until you are able to upgrade to software version 14.1 or later, it is up to the pilot to determine how this vulnerability affects the way the way they fly.
Dynon recommends that affected systems not be flown in IMC if the unavailability of SkyView would jeopardize safety of flight. This would be particularly true for customers who have redundant SkyView systems that do not have independent backup - such as an EFIS-D10A or EFIS-D6 - in the aircraft.
If a SkyView display becomes unresponsive in flight, it can be restarted by pressing buttons 1,2, and 5 simultaneously. Note that you may have to restart all displays in the aircraft for the system to become operable again.
This issue is resolved in SkyView software version 14.1 or later.
Customers affected by this issue should upgrade to SkyView software version 14.1 or later.
Dynon recommends that all customers that are currently running any 14.0 version of software - not just those affected by this bulletin - should upgrade to 14.1.
This technical service bulletin is in effect indefinitely or until superseded by a future bulletin..
