I know a few of you are still flying behind Blue Mountain Avionics EFIS systems. I too have one of the orphaned systems in my aircraft. Up until recently, Greg has been keeping the User Discussion group going on his website. We'll it finally went away and now there's no dedicated site for us to discuss issues and/or solutions with other users of the equipment. I decided to create a Yahoo! Group dedicated to the BMA equipment. If you would like to join, it can be found at...
Again, this has no connection to Greg or the ex- BMA company, just a site for Users to talk to Users.
Flying with an EFIS/Lite Plus and it's working really nicely.
