IFD 5XX/4XX Software Version introduces improvements to the following in AviOS10.3.0.2:

  • Tuned frequencies are not retained across power cycles

  • Secondary standby frequency selection times out after 20 seconds, reverting back to the #1 standby
  • IFD restart may occur if RF legs are disabled, an approach is selected in the dropdown, and every enroute transition to that approach contains an RF leg
  • Devices driven by GAMA 429 (e.g. EX5000, Aspen) don’t show the visual approach extended runway centerline
  • Exit Hold button does not appear when a hold immediately precedes an arrival or approach starting at the hold fix
  • VSR is not computed when the next altitude constraint is on a leg that is part of a departure
  • IFD outputs the selected altitude label even if enroute VNAV is disabled.  In some installations, this can cause autopilot selected altitude to be overridden (e.g. TruTrak connected directly to the IFD).
  • Enroute VNAV deviations not scaled correctly for display on a G5 (see SIL 606-00192-000).
  • Direct-to entry is cancelled when using Keyboard Convenience Mode
  • Some IFDs with multi-engines enabled continue to show fuel flow / quantity in single engine format

To check the current level of the IFD: 


The “Status” LSK is a multiple state LSK that provides access to software status page, weather datalink status page (if datalink is installed and properly configured), GPS status page, and the IFD databases status page.  Pushing the adjacent bezel key or touching the label soft key will cycle through the various status pages. 

Software Status Page 
The “Software” selection will present the top level software part number information and some system-level parameters which can be useful during service calls and IFD feature descriptions.
