In IFD software 10.2.3.1 there was a new setting on the Main System Config page called 'Appr Roll Steer'. The default is enabled. I believe this is the default to emulate the GNS. The techsupport article description ( https://techsupport.avidyne.com/kb/article/284-approach-roll-steering-setting-on-main-system-config-page/" rel="nofollow - https://techsupport.avidyne.com/kb/article/284-approach-roll-steering-setting-on-main-system-config-page/ )is a bit unclear to me:

Approach Roll Steering
Enabled: Default setting.
Disabled: Invalidates GPSS Roll Steering output during FMS approaches. Should be disabled for autopilots that fly GPSS during approach mode to force the autopilots to switch to Left/Right deviation data.

I have dual IFD440's and a DFC90. It would seem I should disable this. Right?
