Hi all,

My OP Technologies EFIS has software Version 3.10
It seems that to upgrade the software beyond 3.10 I need to send my EFIS back
to Aerosonic for a hardware upgrade first.

Could someone please tell me when software version 3.11 became available.
I would be interested to know if it was out before my EFIS was shipped.
I believe they are now up to V 3.18

Happy flying to all
