I didn't ask about it, but they were displaying an EFIS that had a similar form factor as the GRT (e.g. a landscape layout maybe 6-7 in across). It was only showing attitude information, no GPS, HITS, NAV, Engine info. I didn't ask about it so it may support these things... The display unit did not have a working gyro, it was displaying a canned demo. I'll be back on Saturday and get some more information.
